Safety Section
Page 5/8
To ensure that wires are correctly terminated the correct crimp terminal and tool
for the wire size should be used.
The equipment must be connected in accordance with the appropriate connection
diagram.
Protection Class I Equipment
-
Before energizing the equipment it must be earthed using the protective
conductor terminal, if provided, or the appropriate termination of the
supply plug in the case of plug connected equipment.
-
The protective conductor (earth) connection must not be removed since
the protection against electric shock provided by the equipment would be
lost.
-
When the protective (earth) conductor terminal (PCT) is also used to
terminate cable screens, etc., it is essential that the integrity of the
protective (earth) conductor is checked after the addition or removal of
such functional earth connections. For M4 stud PCTs the integrity of the
protective (earth) connections should be ensured by use of a locknut or
similar.
The recommended minimum protective conductor (earth) wire size is 2.5 mm²
(3.3 mm² for North America) unless otherwise stated in the technical data section
of the equipment documentation, or otherwise required by local or country wiring
regulations.
The protective conductor (earth) connection must be low-inductance and as short
as possible.
All connections to the equipment must have a defined potential. Connections that
are pre-wired, but not used, should preferably be grounded when binary inputs
and output relays are isolated. When binary inputs and output relays are
connected to common potential, the pre-wired but unused connections should be
connected to the common potential of the grouped connections.
Before energizing the equipment, the following should be checked:
-
Voltage rating/polarity (rating label/equipment documentation),
-
CT circuit rating (rating label) and integrity of connections,
-
Protective fuse rating,
-
Integrity of
applicable),
-
Voltage and current rating of external wiring, applicable to the application.

Accidental touching of exposed terminals
If working in an area of restricted space, such as a cubicle, where there is a risk of
electric shock due to accidental touching of terminals which do not comply with
IP20 rating, then a suitable protective barrier should be provided.
Equipment use
If the equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.
Removal of the equipment front panel/cover
Removal of the equipment front panel/cover may expose hazardous live parts,
which must not be touched until the electrical power is removed.
Pxxx/EN SS/G11
Page 6/8
Safety Section
UL and CSA/CUL Listed or Recognized equipment
To maintain UL and CSA/CUL Listing/Recognized status for North America the
equipment should be installed using UL or CSA Listed or Recognized parts for
the following items: connection cables, protective fuses/fuseholders or circuit
breakers, insulation crimp terminals and replacement internal battery, as
specified in the equipment documentation.
For external protective fuses a UL or CSA Listed fuse shall be used. The Listed
type shall be a Class J time delay fuse, with a maximum current rating of 15 A
and a minimum d.c. rating of 250 Vd.c., for example type AJT15.
Where UL or CSA Listing of the equipment is not required, a high rupture
capacity (HRC) fuse type with a maximum current rating of 16 Amps and a
minimum d.c. rating of 250 Vd.c. may be used, for example Red Spot type NIT or
TIA.
Equipment operating conditions
The equipment should be operated within the specified electrical and
environmental limits.
Current transformer circuits
Do not open the secondary circuit of a live CT since the high voltage produced
may be lethal to personnel and could damage insulation. Generally, for safety,
the secondary of the line CT must be shorted before opening any connections to
it.
For most equipment with ring-terminal connections, the threaded terminal block
for current transformer termination has automatic CT shorting on removal of the
module. Therefore external shorting of the CTs may not be required, the
equipment documentation should be checked to see if this applies.
For equipment with pin-terminal connections, the threaded terminal block for
current transformer termination does NOT have automatic CT shorting on removal
of the module.
External resistors, including voltage dependent resistors (VDRs)
Where external resistors, including voltage dependent resistors (VDRs), are fitted
to the equipment, these may present a risk of electric shock or burns, if touched.
Battery replacement
Where internal batteries are fitted they should be replaced with the recommended
type and be installed with the correct polarity to avoid possible damage to the
equipment, buildings and persons.
Insulation and dielectric strength testing
Insulation testing may leave capacitors charged up to a hazardous voltage. At the
end of each part of the test, the voltage should be gradually reduced to zero, to
discharge capacitors, before the test leads are disconnected.
Insertion of modules and pcb cards
Modules and PCB cards must not be inserted into or withdrawn from the
equipment whilst it is energized, since this may result in damage.
Insertion and withdrawal of extender cards
Extender cards are available for some equipment. If an extender card is used,
this should not be inserted or withdrawn from the equipment whilst it is energized.
This is to avoid possible shock or damage hazards. Hazardous live voltages may
be accessible on the extender card.
Pxxx/EN SS/G11
Safety Section
Page 7/8
External test blocks and test plugs
Great care should be taken when using external test blocks and test plugs such
as the MMLG, MMLB and MiCOM P990 types, hazardous voltages may be
accessible when using these. *CT shorting links must be in place before the
insertion or removal of MMLB test plugs, to avoid potentially lethal voltages.
*Note: When a MiCOM P992 Test Plug is inserted into the MiCOM P991 Test
Block, the secondaries of the line CTs are automatically shorted, making
them safe.
Fiber optic communication
Where fiber optic communication devices are fitted, these should not be viewed
directly. Optical power meters should be used to determine the operation or
signal level of the device.
Cleaning
The equipment may be cleaned using a lint free cloth dampened with clean water,
when no connections are energized. Contact fingers of test plugs are normally
protected by petroleum jelly, which should not be removed.
5.
DECOMMISSIONING AND DISPOSAL
De-commissioning
The supply input (auxiliary) for the equipment may include capacitors across the
supply or to earth. To avoid electric shock or energy hazards, after completely
isolating the supplies to the equipment (both poles of any dc supply), the
capacitors should be safely discharged via the external terminals prior to
de-commissioning.
Disposal
It is recommended that incineration and disposal to water courses is avoided.
The equipment should be disposed of in a safe manner. Any equipment
containing batteries should have them removed before disposal, taking
precautions to avoid short circuits. Particular regulations within the country of
operation, may apply to the disposal of the equipment.

Outputs
Impulse Output for the tripping coil
(ordering option)
Trip energy:
- Hardware version P115746x1xxxxxx:
E ≥ 0.1 J, 24 Vdc -0% to +10%
- Hardware version P115746x2xxxxxx::
E ≥ 0.02 J, 12 Vdc -0% to +10%
Impulse Output for flag indicator or
auxiliary relay
Trip energy: E ≥ 0.01 J
Voltage: 24 Vdc -0% to +10%
Note: The tripping energy for the tripping
coil/flag indicator is stored by a capacitor
built into the protection relay. The
capacitors are loaded by a current or the
auxiliary voltage. The duration of the trip
pulse is 50 ms. The pause between the
individual pulses depends on the
impedance of the tripping coil/flag
indicator coil/flag indicator and on the
current level. The pulse lasts as long as
the activation threshold is exceeded.

Protection Functions
Note: All settings and measurements are given
as a multiple of the In (Ien) current value
(ordering option)
Operation time
The typical operation time, if the P115 is
supplied from Vx or if the current is above
0.2 In (Ien): ≤ 40ms
If the pre-fault current is below 0.2 In (Ien) in all
phases and that there is no Vx on the 11 -12
terminals, additional time correction should be
applied for the operation time (measured on
the outputs contacts):
(i) Hardware ver. P115746x0xxxxxx
(without energy output for low energy
tripping coil) for all types of fault
(1, 2, 3-phases):
≤ 25mA,
except 1-phase fault, where the current
is below 1.6 In (Ien)
≤ 30mA,
(ii) Hardware ver. P115746x1xxxxxx (with
energy output for low energy tripping coil
24VDC 0.1Ws) and P115746x2xxxxxx
(with energy output for low energy
tripping coil 12VDC 0.02Ws):
- for faults where the current is ≤ 0.6 In
(Ien):
1-phase fault: ≤ 60ms
2-phase fault: ≤ 60ms
3-phase fault: ≤ 30ms
- for all types of fault where the current is
> 0.6 In (Ien) (1, 2, 3-phases): ≤ 30ms
The correction time measured on energy
outputs is 6ms shorter than that measured on
output contacts.
Note: The tripping time in case of a fault if the
pre-fault current is below 0.2 In and
there is no auxiliary voltage (Vx) on
terminals 11 -12 is the sum of the set
time delay, the operation time and the
correction time (see above).
Protection Accuracy
Note:
1. All data below are given for inception of
fault from currents above 0.2 In (Ien) at
least in 1 phase or if the P115 is powered
from the Vx auxiliary voltage supply.
If the pre-fault current is below 0.2 In (Ien)
in all phases and that there is no Vx on
terminals 11 -12 additional time correction
should be taken into account (see above)

Auxiliary Supply Voltage (Vx) connection
Before applying the auxiliary supply voltage to the relay, check that the rated nominal ac or
dc voltage is appropriate for the application and that it will be connected to the correct
terminals (11&12). The relay's serial number, current rating, and power rating information
can be viewed on the upper side of the case. The ac or dc supply voltage must be within the
corresponding nominal range of the device, as indicated in the table below, for the
appropriate nominal rating of the equipment:
Nominal ranges of auxiliary
voltage Vx
Operative dc Range
Operative ac Range
24 to 48 Vac/dc
19 to 58 Vdc
19 to 53 Vac
60 to 250 Vdc and
60 to 240 Vac
48 to 300 Vdc
48 to 265 Vac
Once the ratings have been verified for the application, connect the equipment to an external
power source capable of delivering the requirements specified on the label, to perform the
relay familiarization procedures. Please refer to the wiring diagrams in the Installation
section for complete installation details, ensuring that the correct polarities are observed in
the case of dc supply.
Note:
1.3.2
The label specifies Vx for both the P115 supply input and binary
inputs.
Current inputs
The measuring current inputs of the P115 should be connected to the secondary wires of the
power system CTs as shown in the connection diagrams in section 8 of P115 Installation
chapter P115/EN IN.
The parameters of the CTs which can be connected to the P115’s current input terminals are
detailed in section 3 of chapter P115/EN AP - Applications.
1.3.3
Tripping coil output (ordering option)
Terminals 29 and 30 (3rd block terminal) are used for the connection of the CB's low energy
tripping coil (ordering option)
The trip energy is provided by capacitors built into the P115. The trip command is a 50 ms
pulse and its repetition depends on the tripping coil's impedance and on the current value.
Repetition continues until the tripping current criteria are reset.
The trip voltage on terminals 29 and 30 depends on the ordering option:
1.3.4
-
24 Vdc, trip energy ≥ 0.1 Ws
-
12 Vdc, trip energy ≥ 0.02 Ws
Flag indicator output
Terminals 27 and 28 (3rd block terminal) are used for the connection of an external flag
indicator.
The flag indicator can be used for trip signaling. The flag indicator output is supplied from a
built -in capacitor different from the trip coil output (terminals 29 and 30).
The trip command is a 50ms pulse, its repetition depends on the external relay's impedance
(flag indicator coil) and on the current value. Repetition continues until the tripping current
criteria are reset.
The voltage on terminals 27 and 28 is greater than 24 Vdc. The trip energy is greater than
0.01 Ws.

1.3.7
Binary inputs
The P115 has 2 binary inputs: L1 (terminals 13-15) and L2 (terminals 14-15)
The P115 is delivered with the following default factory settings for inputs:
-
input L1 is not configured.
-
input L2 is not configured.
To change input configuration refer to section 1.2.3 of chapter P115/EN ST - Settings.
The input connection diagram is shown in section 8 of chapter P115/EN IN - Installation.
1.4
Introduction to the user interfaces and settings options
The relay has a USB user interface for MiCOM S1 software.
By using this interface it is possible to download the setting values, last 5 fault records and
make a full configuration of P115
NOTE:
After connection to the USB port the “Healthy” LED is lit. If the LED is
not lit refer to chapter P115/EN TS - Troubleshooting.
The USB port integrates electronic boards only to allow communications with the P115 via
the HMI/RS485/USB interfaces.
1.5
Changing parameters via the front panel.
Changing of all parameters is password-protected.
After restart or applying of power supply, the P115 is in Protection Mode. This means that all
settings are the same as in the relay's operation system and are available on the front
panel.
To change any parameters, it is necessary to switch the P115 to the SETTING CHANGE
MODE.
The SETTING CHANGE MODE is indicated by the sequential flashing of the programmable
LEDs (from 3 up to 8 LEDs) on the front panel.
Until it is switched back from the SETTING CHANGE MODE to the PROTECTION MODE, or
restarted by disconnecting then reconnecting the power supply, the P115 uses the setting
parameters that were active before the SETTING CHANGE MODE was entered (previous
settings).
Getting Started
P115/EN GS/A41
MiCOM P115
(GS) 3-9/24
Press the ENTER key after changing a chosen parameter (confirmation of change). The new
value is saved in FRAM memory but the P115 still uses the setting value which was active
before the SETTING CHANGE MODE was entered (previous settings). The new value will
be available in the operation system only after the firmware has been reset. When the
firmware is reset, all the settings stored in FRAM memory are loaded into the P115 system.
When switching from the SETTING CHANGE MODE to the PROTECTION MODE, a warm
reset is applied.
The P115 therefore applies the new parameters to the relay's operation system.
Afterwards, the settings available on the front panel those used by the operation system are
coherent.
NOTE:
While the LEDs are flashing (SETTING CHANGE MODE) there can
be a mismatch between the settings displayed on the front panel and
those used by the operating system.
The password protection of the relay comprises three levels:
•
Administrator (Without limits)
•
Protection setting (Protection only)
•
Control only (Test control)
Administrator rights: all the menu settings may be changed.
Protection setting rights: it is possible to change settings in the PROTECTION column, CB
control and reset of the counters are also possible.
Control rights: CB control from the front panel only.
For each level the password consists of 5 digits (0 to 9)
The default password is 00000.
If the first password is different, this means that the ‘Administrator’ password has been
changed.
The Protection setting password is still 00000. Therefore, to protect settings against
unauthorized access it is necessary to change the Protection setting password by first
entering 00000 then a new value.
The Control password is still 00000. Therefore, if it is necessary to change it, first enter
00000 then the new value (Control right) of the password.
NOTES:
1.
If the Protection setting rights have not been changed, or if it has been
set to the default value (00000), it is possible to change all the settings
in the PROTECTION column, reset the counters and control the CB
without entering a password, simply by pressing the ENTER key. This
makes it possible to change a chosen parameter by automatically
switching the P115 to the SETTING CHANGE MODE (the
programmable LEDs are flashing).
This means that even after changing only one parameter it is
necessary to switch the P115 back to PROTECTION MODE in order
to activate the new settings (warm restart).
2.
If the Control rights password has not been changed or if it has been
set to the default value (00000) it is possible to control the CB or
choose the older faults in Fault Record column without password
protection.

SETTING CHANGE MODE
The SETTING CHANGE MODE should be used to change settings.
Using the SETTING CHANGE MODE ensures that all changed parameters will be applied
simultaneously so as to avoid any problems caused by possible setting inconsistencies.
The SETTING CHANGE MODE makes it possible to change settings while the relay is active
without any risk (the P115 continues to use the previous settings).
After exiting the SETTING CHANGE MODE a warm reset of firmware is applied so that all
the protection counters are reset.
NOTE:
Latched LEDs and outputs are not reset (stored values are not
cleared during a P115 reset)
To switch the P115 to SETTING CHANGE MODE navigate to the SETTING CHANGE

ALARM STATUS (see Figure 4) information is available if the cause of alarm has been
triggered. Therefore, if after pressing the DOWN key no the new cell is displayed, it means
that no alarms have been detected.
Depending on the P115 configuration an alarm signal is self-resetting (no cause of alarm –
no alarm signal; GLOBAL SETTINGS/LOC/Alarm Display 0: Self-Reset) or manually
resettable (alarm signal latched; GLOBAL SETTINGS/LOC/Alarm Display 1: Manual Reset).
Default setting: 0: Self-Reset. This means that if an alarm signal has disappeared no
information is available in the ALARM STATUS column.
If Manual Reset is set, this means that if an alarm signal has disappeared the corresponding
information is still available in the ALARM STATUS column up until it is reset in the ALARM
STATUS/ Alarm Reset cell.
Alarm information is always available in the event recorder. However, the programmable
LEDs can be used to store causes of alarm if required.
Figure 4 shows all causes of alarms (if alarms have been enabled in the main configuration
column of the protection function).

GENERAL INFORMATION
The P115 must be configured to the system and application by means of the appropriate
settings. This section gives instructions for determining the settings, which are located in the
folder entitled, Schneider Electric in the menu tree. The order in which the settings are listed
and described in this chapter is: the protection settings, control and configuration settings
(see section P115/EN GS for the detailed relay menu map). The relay is supplied with a
factory-set configuration of default settings.
All current settings refer to nominal current (ordering option: 1 A or 5 A). The nominal
current can be defined separately for phase (In) and earth (Ien) currents in the ordering
process (ordering hardware option).
MiCOM S1 can be used to download and upload protection and configuration setting values
via the relay's USB port.
The protection and I/O settings include all the following items that become active once
enabled in the configuration column of the relay menu database:
−
Protection element settings.
−
Output settings
−
Input settings
−
LED settings
There are two groups of protection and I/O settings, with each group containing the same
setting cells. One group of protection and I/O settings is selected as the active group, and is
used by the protection elements. The settings for group 1 are shown. The settings are
discussed in the same order in which they are displayed in the menu.
The menu structure is as follows:
- DEFAULT WINDOW (Currents in multiples of In, currents in Amps, CB Control window)
- ALARM STATUS

Phase O/C [50/51]
The overcurrent protection included in the P115 relay provides three-stage non-directional
three-phase overcurrent protection with independent time delay characteristics.
All overcurrent settings apply to all of the three phases but are independent for each of the
three stages.
The first two overcurrent stages have time-delayed characteristics which are selectable
between inverse definite minimum time (IDMT), or definite time (DMT). The third stage has
definite time characteristics only.

E/Gnd Fault [50N/51N]
The earth fault element operates from earth fault current that is measured directly from the
system; either by means of a separate CT located in a power system earth connection or via
a residual connection of the three line CT's.
All overcurrent settings are independent for each of the two stages.
The first stage of e/f non-directional overcurrent protection has time-delayed characteristics
which are selectable between inverse definite minimum time (IDMT), or definite time (DMT).
The second stage has definite time characteristics only.

CB Fail [50BF]
This function consists of a circuit breaker fail function that can be initiated by:
•
Current based protection elements
•
External protection element: CBF ext..
For current-based protection, the reset condition is based on undercurrent operation to
determine whether the CB has opened.
It is common practice to use low set undercurrent elements in protection relays to indicate
that circuit breaker poles have interrupted the fault or load current, as required.

IN connection
0:terminals:7-9
0:terminals:7-9
1:terminals 8-9
This cell is used to inform the P115 about the IN connection: with or without powering of
the P115.
The above information is used by the P115 to reduce its energy consumption for low
currents if the auxiliary supply is not connected to the 11-12 terminals.
Reducing its energy consumption allows the P115 to lower its burden on the primary MV
CT.
The minimum current required to power the P115 via the CT is 0.2In, but if the CT's energy
is low, the P115 switches off its LCD display, LEDs and RS485 communications when a
fixed energy threshold is reached. The remaining functionalities of the P115 remain active
(inputs, event recorder, fault recorder, counters, latching of LEDs and output contacts, etc).
The value used by this low energy threshold is calculated as a sum of the currents which
supply the P115.
If the sum of the currents exceeds 0.5In (for example the sum: 0.5In= Ia:0.25In +
Ib:0.25In+ Ic:0In + IN:0Ien) the LCD display, LEDs and RS485 are switched back on.
Depending on the IN connection setting: the earth current is included in the above sum
(0:terminals:7-9) or not (1:terminals 8-9)
In a typical application, every type of fault with current values greater than 0.25In, gives a
sum greater than 0.5In (phase to phase or phase to earth fault).
Note: if the energy level is below 0.5In, RL2, RL3, RL4 are not energized either, but if they
are set as latching, when the P115 is powered again the latched RL2, RL3 and RL4 relays
will remain energized until they are reset. The same applies to latched LEDs.

HARDWARE OPERATION
The P115 is supplied from power system CTs or/and from auxiliary voltage supply
(terminals: 11-12). In case of loss of auxiliary voltage on the 11-12 terminals, the operation of
the P115 requires a minimum current flowing in one of the three phases or earth fault input
(7-9 terminals). The minimum current required for operation is 20% of the nominal current of
the relay (Technical Data Section P115/EN TD).
The energy taken from the current and/or from auxiliary voltage supply is used to charge up
the integrated capacitors: trip outputs and relay outputs (flag indicator). If any protection
function trips, the energy is provided to the 29-30 (CB coil output) and 27-28 (flag indicator
output) terminals. The output signal is a pulse, the repetition of which is dependent on the
trip coil's impedance and on the current level.
If the current in one of the three phases or at earth fault input (7-9 terminals) is above 0.2 In
(Ien), the following functions:
-
output contact: RL1,
-
all inputs (L1, L2),
-
event recording,
-
fault record recording,
-
memorizing of latched LEDs and outputs information,
-
memorizing of counter information,
are operational, even if there is no auxiliary voltage on 11-12 terminals.
If the sum of the currents which supply P115 is below 0.5In (for example the sum: 0.5In=
Ia:0.25In + Ib:0.25In+ Ic:0.00In + IN:0.00Ien) when a loss of auxiliary voltage supply occurs,
the following functions are no longer available:
- the RS485 communication port is switched off (no communication with the control
system via the RS485 link),
-
the LCD display is switched off,
-
the LEDs are switched off. If after a switch-on-to-fault operation, the P115 is supplied
again (currents above 0.5 In or auxiliary power or USB), the stored LED information will
be displayed until it is reset,
-
RL2, RL3, RL4 are not energized. If after a switch-on-to-fault operation, the P115 is
supplied again (currents above 0.5 In or auxiliary power or USB), the stord output relay
information will be energized until it is reset.
Depending on the IN connection setting: the earth current is a part of the above sum
(0:terminals:7-9) or not (1:terminals 8-9)
In a typical application, every type of a fault with current values greater than 0.25In gives a
sum greater than 0.5In (phase to phase or phase to earth fault).
NOTE:
1.
A back-up clock capacitor is charged from an auxiliary voltage supply
(terminals 11-12) only. The capacitor's energy allows storage of real
time information for up to 2 days. When the back-up capacitor is
completely discharged, it takes less than 10 minutes to recharge it
completely.
2.
If the clock has no real time information (the back-up capacitor is
recharged) and the current exceeds the minimum current required for
operation, the real time is set to 01/01/2008 00:00:00. Therefore
events are dated with reference to this start time value.

3.
If RS485 communications are required, it is recommended to supply
P115 from the auxiliary voltage in order to ensure that real time
information is used in the event and fault recorders.
4.
The FRAM memory (settings, events, fault records, latched LEDs and
outputs information) is a non-volatile memory.
5.
The USB port integrates electronic boards only to allow
communications with the P115 via the user interface (HMI) or the
setting software. Therefore the status of inputs and outputs is not read
via the P115 system. The status information available on the menu is
set to its default value. Healthy information available on the Healthy
LED refers to the electronic part supplied via the USB port.
6.
In case of any hardware problems the “Healthy LED” is blinking. If the
“Healthy LED” is not lit, this means that no source of supply is
available or that P115 is not healthy. For CT powered relays it is not
possible to differentiate between the above conditions. Output
contacts can also be configured to the “Healthy” function (Setting
Section P115/EN ST).

OPERATION OF INDIVIDUAL PROTECTION FUNCTIONS
The following sections detail the individual protection functions.
2.1
Overcurrent protection
The overcurrent protection included in the P115 relays provides three-stage non-directional
three-phase overcurrent protection with independent time delay characteristics.
All
overcurrent settings apply to all three phases but are independent for each of the three
stages.
The first (I>) and second (I>>) stage of overcurrent protection has time-delayed
characteristics which are selectable between inverse definite minimum time (IDMT), or
definite time (DMT). The third (I>>>) stage has a definite time characteristic only.
Various methods are available to achieve correct relay co-ordination on a system; by means
of time alone, current alone or a combination of both time and current. Grading by means of
current is only possible where there is an appreciable difference in fault level between the
two relay locations. Grading by time is used by some utilities but can often lead to excessive
fault clearance times at or near source substations where the fault level is highest. For these
reasons the most commonly applied characteristic in coordinating overcurrent relays is the
IDMT type.
The inverse time delayed characteristics indicated above comply with the following formulae:

INTRODUCTION
1.1
Protection of feeders
The secure and reliable distribution of power within a network is heavily dependent upon the
integrity of the underground cables which link the various sections of the network together.
As such, the associated protection system must also provide both secure and reliable
operation.
The most common fault conditions, on both MV transformers and cables, are short circuit
faults. Such faults may occur between phases but will most often involve one or more
phases becoming short circuit to earth. Faults of this nature require the fastest possible fault
clearance times but at the same time allowing suitable co-ordination with other downstream
protection devices.
The effect of fault resistance is more pronounced on lower voltage systems, resulting in
potentially lower fault currents, which in turn increases the difficulty in the detection of high
resistance faults. In addition, many distribution systems use earthing arrangements
designed to limit the passage of earth fault current. Methods such as resistance earthing,
Petersen Coil earthing or insulated systems make the detection of earth faults difficult.
Special protection requirements are often used to overcome these problems.
The CT-powered P115 is used in MV switchboards with circuit breakers to protect
distribution transformers, feeders, and lines in local and industrial power systems. The small
compact case allows this relay to be used in these situations.
Due to the dual powered function, P115 can be used as back-up protection of HV/MV
transformers.
Before carrying out any work on the equipment, the user should be
familiar with the contents of the Safety Guide SFTY/4L M/E11 or later
issue, OR the safety and technical data section of the technical manual
and also the ratings on the equipment rating label.
For safety reasons, no work must be carried out on the P115 until all
power sources to the unit have been disconnected.

2.1
Overcurrent protection
Overcurrent relays are the most commonly used protective devices in any industrial or
distribution power system. They provide main protection to both feeders and busbars when
unit protection is not used. They are also commonly applied to provide back-up protection
when unit systems, such as pilot wire schemes, are used.
There are a few application considerations when applying overcurrent relays.
2.1.1
Transformer magnetizing inrush
When applying overcurrent protection to the MV side of a power transformer it is usual to
apply a high set instantaneous overcurrent element in addition to the time delayed low-set, to
reduce fault clearance times for MV fault conditions. Typically, this will be set to
approximately 1.3 times the LV fault level, so that it will only operate for MV faults. A 30%
safety margin is sufficient due to the low transient overreach. Transient overreach defines
the response of a relay to DC components of fault current and is quoted as a percentage.
The second requirement for this element is that it should remain inoperative during
transformer energization, when a large primary current flows for a short period during switchon. In most applications, the requirement to set the relay above the LV fault level will
automatically result in settings that will be above the level of magnetizing inrush current.
Both overcurrent stages operate on True RMS component. Hence, for the second
overcurrent stage in P115 relays, it is possible to apply settings corresponding to 35% of the
peak inrush current, whilst maintaining stability for the condition.

(AP) 6-5/22
Application of timer hold facility for IEC/IEEE/US IDMT characteristics
This feature may be useful in certain applications, for example when grading with upstream
electromechanical overcurrent relays, which have inherent reset time delays. Setting the
hold timer to a value other than zero, delays the resetting of the protection element timers for
this period, thus allowing the element to behave similarly to an electromechanical relay.
Another possible situation where the timer hold facility may be used to reduce fault clearance
times is where intermittent faults may be experienced. An example of this may occur in a
plastic insulated cable. In this application it is possible that the fault energy melts and
reseals the cable insulation, thereby extinguishing the fault. This process repeats to give a
succession of fault current pulses, each of increasing duration with reducing intervals
between the pulses, until the fault becomes permanent.
When the reset time of the overcurrent relay is instantaneous, the relay will be repeatedly
reset and unable to trip until the fault becomes permanent. By using the Timer Hold facility
for IDMT characteristics the relay will integrate the fault current pulses, thereby reducing fault
clearance time.
For IDMT it is possible to set the timer hold facility based on the following formulae:
IEC: reset time = TMS ⋅
tr
1− M 2
IEEE and US: reset time = TD ⋅

Setting guidelines
When applying the overcurrent protection provided in the P115 relays, standard principles
should be applied in calculating the necessary current and time settings for co-ordination

The example detailed below shows a typical setting calculation and describes how the
settings are applied to the relay.
Assume the following parameters for a relay feeding an LV switchboard:

=
500 A/1 A
Full load current of circuit
=
440 A
Slowest downstream protection
=
100 A Fuse
The current setting employed on the P115 relay must account for both the maximum load
current and the reset ratio of the relay itself:
I> must be greater than: (440 A/0.95)/500 A = 0.9263 In
I> must be greater than: 0.9263 In
For setting range 0.2-4 In step is 0.01 In, so the closest I> set value=0.93 In:
A suitable time delay characteristic can now be chosen. When coordinating with
downstream fuses, the applied relay characteristic should be closely matched to the fuse
characteristic. Therefore, assuming IDMT co-ordination is to be used, an IEC Extremely
Inverse (EI) time characteristic would normally be chosen.
AP
Finally, a suitable time multiplier setting (TMS) must be calculated and entered.

DT threshold
The first and the second stage of the overcurrent characteristic for phase current (I>, I>>)
and e/f current (IN>) can be configured with a definite time (DT) delay or an IDMT
characteristic.
The third O/C stage (I>>>) and the second e/f (IN>>) stage are DT only.
2.1.5
IDMT threshold
The first and the second phase (I>, I>>) and e/f (IN>) overcurrent threshold can be selected
with an independent definite maximum time (IDMT) characteristic.
The time delay in relay operation is calculated with a mathematical formula which depends
on the relay current and TMS (IEC and UK) or TD (IEEE/ANSI and US) values.

The rectifier protection feature is based upon the inverse time/current characteristic as used
in the MCTD01 (Silicon Rectifier Protection Relay) and the above diagrams show a typical
application.
The protection of a rectifier differs from the more traditional overcurrent applications in that
many rectifiers can withstand relatively long overload periods without damage, typically
150% for 2 hours and 300% for 1 min.
The I> setting should be set to typically 110% of the maximum allowable continuous load of
the rectifier. The relay gives start indications when the I> setting has been exceeded, but
this is of no consequence, as this function is not used in this application. The rectifier curve
should be chosen for the inverse curve as it allows for relatively long overloads even with a
110% I> setting.
Typical settings for the TMS are:
Light industrial service TMS = 0.025
Medium duty service TMS = 0.1
Heavy duty traction
TMS = 0.8

The high set is typically set at 8 times rated current as this ensures HV AC protection will
discriminate with faults covered by the LV protection. However, it has been known for the
high set to be set to 4 or 5 times where there is more confidence in the AC protection. Use of
the thermal element to provide protection between 70% and 160% of rated current could
enhance the protection. It is also common practice to provide restricted earth fault protection
for the transformer feeding the rectifier. See the appropriate section dealing with restricted
earth fault protection.
2.3
Earth fault protection
Earth fault (E/F) current is measured on the e/f input.
Depending on the connection on the terminals e/f input can supply P115 (terminals 7 and 9)
or not supply the P115 (terminals 8 and 9).
Two stages are available: IN> and IN>>. The first stage has IDMT or DT characteristics.
The types of characteristics are the same as for I> (refer to section 2.1.5).
If the e/f CT is connected to terminals 7 and 9 and auxiliary voltage supply is not connected
to terminals 11-12, the current on e/f input has to be greater than 0.2Ien to supply P115.
2.3.1
Calculation of the required E/F settings
The setting value of E/F overcurrent protection should be greater (with safety margin) than
the charging currents flowing in the protected line to prevent an earth fault in other parts of
the system tripping the relay. The value of the safety coefficient depends on the application
and accuracy of obtained earth fault current value (typically : 1.5 to 2.5).
2.4
External trip
Binary Input can be configured to CB trip by using AUX1 or AUX2 functions.
AUX1 and AUX2 functions have a timer so a trip can be time-delayed.
tAUX1 and tAUX2 can be configured to:
-
RL1,
-
RL2,
-
RL3,
-
RL4,
-
Trip (protection trip),
-

-
Programmable LEDs.
If it is configured to Trip (protection trip), tAUX1 and/or tAUX2 lit “Trip” LED.
2.5
Blocked overcurrent protection
Blocked overcurrent protection involves the use of start contacts from downstream relays
wired onto blocking inputs of upstream relays. This allows identical current and time settings
to be employed on each of the relays involved in the scheme, as the relay nearest to the
fault does not receive a blocking signal and hence trips discriminatively. This type of
scheme therefore reduces the amount of required grading stages and consequently fault
clearance times.
The principle of blocked overcurrent protection may be extended by setting fast acting
overcurrent elements on the incoming feeders to a substation which can then be blocked by
start contacts from the relays protecting the outgoing feeders. The fast acting element is
thus allowed to trip for a fault condition on the busbar but is stable for external feeder faults
by means of the blocking signal. This type of scheme therefore provides much reduced fault
clearance times for busbar faults than would be the case with conventional time graded
overcurrent protection. The availability of multiple overcurrent and earth fault stages means
that back-up time graded overcurrent protection is also provided. This is shown in Figures 4

Circuit breaker fail protection (CBF)
Following the inception of a fault one or more main protection devices will operate and issue
a trip output to the circuit breaker(s) associated with the faulted circuit. Operation of the
circuit breaker is essential to isolate the fault, and prevent damage / further damage to the
power system. For transmission/sub-transmission systems, slow fault clearance can also
threaten system stability. It is therefore common practice to implement circuit breaker failure
protection, which monitors that the circuit breaker has opened within a reasonable time.
If the fault current has not been interrupted following a set time delay from the circuit
breaker's trip initiation, breaker failure protection (CBF) will operate.
CBF operation can be used to back-trip upstream circuit breakers to ensure that the fault is
isolated correctly. CBF operation can also resets all start output contacts, ensuring that any
blocks asserted on upstream protection are removed.
2.6.1
Reset mechanisms for breaker fail timers
It is common practice to use low set undercurrent elements in protection relays to indicate
that the circuit breaker's poles have cleared the fault or load current, as required.
This covers the following situations:
•
Where a circuit breaker's auxiliary contacts are defective, or cannot be relied upon to
definitely indicate that the breaker has tripped.
•
Where a circuit breaker has started to open but has become jammed. This may result in
continued arcing at the primary contacts, with an additional arcing resistance in the fault
current path. Should this resistance severely limit fault current, the initiating protection
element may reset. Thus, reset of the element may not give a reliable indication that the
circuit breaker has opened fully.
For any protection function requiring current to operate, the relay uses operation of
undercurrent elements (I<) to detect that the necessary circuit breaker poles have tripped
and reset the CB fail timers. However, the undercurrent elements may not be reliable
methods of resetting circuit breaker fail in all applications. For example:
•
With non-current operated protection, such as CB Ext. Here, I< only gives a reliable
reset method if the protected circuit would always have load current flowing. Detecting
drop-off of the initiating protection element might be a more reliable method.
•
With non-current operated protection, such as CB Ext. Again using I< would rely upon
the feeder normally being loaded. Also, tripping the circuit breaker may not remove the
initiating condition from the busbar, and hence drop-off of the protection element may not
occur. In such cases, the position of the circuit breaker auxiliary contacts may give the
best reset method.
Resetting of the CBF is possible from a breaker open indication (from the relay’s pole dead
logic) or from a protection reset. In these cases resetting is only allowed provided the
undercurrent elements have also reset.

Note that all the CB Fail resetting methods involve the operation of the undercurrent

should still be used if this proves to be the worst case.
The examples above consider direct tripping of a circuit breaker. Note that where auxiliary
tripping relays are used, an additional 10-15ms must be added to allow for trip relay
operation.
AP
2.6.2.2
Breaker fail undercurrent settings
The phase undercurrent settings (I<) must be set less than load current, to ensure that I<
operation indicates that the circuit breaker pole is open. A typical setting for overhead line or
cable circuits is 20% In, with 5% In common for generator circuit breaker CBF.
The standard earth fault undercurrent element must be set to less than the trip setting,
typically as follows:
IN<
= (IN> trip) / 2

(AP) 6-13/22
Minimum tripping time
The minimum tripping time when the relay is switched on to a fault is subject to the fault
current level.
When the current is greater than the fault current level by 0.2 x In (Ien) ("hot start") the
minimum trip time can be defined as follows:
Time delay setting + Operation time (measuring algorithm time delay + time to decision +
energizing time of output contact ).
Typical operation time: ≤ 40 ms
The minimum setting for the DT time delay (I>>>) is: 0 ms for overcurrent and 0 ms for earth
fault. For I>, I>> and IN>>, the minimum time delay setting is 0.02 s.
The minimum tripping time for the “hot start” (capacitors are charged within the unit) for 0ms
set time delay is: 0 ms + 40 ms = 40 ms
If there was no current flowing through the relay terminals before the occurrence of a fault
and that a fault condition occurs, or if the current in all the analog inputs is lower than 0.2 In
(0.2 Ien), the minimum tripping time from the “cold start” (capacitors not charged) with a
40 ms set time delay is equal to 0 ms + 40 ms + time correction value.
Time correction value (measured at the output contacts):
(i) Hardware version P115746x0xxxxxx (without energy output for the low energy tripping
coil)
•
for all types of fault (1, 2, 3-phase):
•
except 1-phase fault currents below 1.6 In (Ien):
≤ 25 mA,
≤ 30 mA,
(ii) Hardware version P115746x1xxxxxx (with energy output for the low energy tripping coil,
24 Vdc: 0.1 W) and P115746x2xxxxxx (with energy output for the low energy tripping coil,

for all types of fault currents above 0.6 In (Ien) (1, 2, 3-phases):

For P115 without low energy tripping coil output (P115746x0xxxxxx) the minimum tripping
time from the “cold start” with a 0 ms set time delay is equal to
< 0 ms + 40 ms + 30 ms= 70 ms
Typically it is around 65 ms.
The correction time measured on the energy outputs is 6ms shorther than the time
measured on the output contacts.

CT REQUIREMENTS
For the conventional case of a resistive load, the voltage at the secondary winding of the
transformer is proportional to the primary current, therefore the error remains constant.
In the case of a MiCOM P115 self-powered protection relay, this no longer applies, since the
voltage at the input of the protection circuit is in a non-proportional ratio to the input current.
The best solution to check whether the MiCOM P115 relay is adapted to a given CT is to
have available the magnetization curve and the internal resistance of the CT in question.
To guarantee good accuracy at low current levels, the magnetizing current of the CT must be
low. In other words, the input voltage of the relay must be sufficiently low compared with the
knee-point voltage Vk of the CT.
The following sections show the ac burden of the P115 MiCOM relay and, taking into
account the magnetizing curve of a CT, it is then possible to determine the accuracy of the
system as a whole for the entire current range: P115 + associated CT.
3.1
Recapitulation of the current transformer's characteristics
3.1.1
Characterization of a current transformer
The characteristics of a protection relay CT are based on:
AP
•
Its rated output burden expressed in VA, its relevant accuracy class (5P or 10P) and the
accuracy limit current (5 In, 10 In, 15 In, 20 In). The accuracy limit factor (K) is the
ratio between the precision limit current and the nominal current rating.
•
Naturally, the transformation ratio of the CT is to be added to this. This ratio is the ratio
of the primary current to the secondary current I1/I2. The secondary current rating is
generally 1 A or 5 A.
•
Other characteristics such as the insulating voltage or the thermal behavior are also
taken into account.
Standard BS 3938 proposes a specification identical to that of IEC 185 for class P
transformers. The CT is characterized in accordance with a second class known as X class
(Cx) which, in addition to the calculated ratio, requires a knee-point voltage Vk and an
internal resistance Rct.
The following quantities are associated with the magnetization curve of a CT:
•
The knee-point voltage Vk, which is determined by the point on the curve V=f (Im )
beyond which an increase of 10% in the voltage V results in a 50% increase of the
magnetizing current.
•
The voltage related to the accuracy limit of the CT.
- For a 5PK CT (accuracy class 5P, accuracy limit factor K):
At the saturation voltage Vs1 we will have a 5% accuracy on the current K * In.
- For a 10PK TC (accuracy class 10P, accuracy limit factor K):
At the saturation voltage Vs2 we will have a 10% accuracy on the current K * In.

•
Rct : secondary winding resistance of CT (ohms)
AP
Figure 7:
Equivalent diagram of a current transformer
The magnetizing current Im of the transformer depends on the voltage generated at the
secondary windings of the transformer.
It is this current that introduces an error signal into the measurement. If the CT were perfect,
the magnetizing current would be null.
3.1.3
How to calculate the rated burden, in VA, of a CT based on its characteristic quantities (Vk,
Rct)
The saturation voltage is derived using the following formula: Vs = (Rct + Rp ) Is
The nominal load impedance of the CT is Rp = Pn /In2
We have Vs = (Rct + Pn /In2 ) Is
Hence: Pn = (Vs/Is - Rct ) In2
•
For a transformer with in a 5P accuracy class: Vs1/Vk = 1.6/1.4
Thus: Vs1 = 1.6/1.4 * Vk, at Is1 equals K * In
Hence: Pn = [(1.6/1.4 * Vk )/K * In - Rct ] * In2
Application Notes
P115/EN AP/A41
MiCOM P115
•
(AP) 6-17/22
For a transformer with a 10P accuracy class: Vs2/Vk = 1.9/1.4
thus Vs2 = 1.9/1.4 * Vk, at Is2 equals K * In
Hence: Pn = [(1.9/1.4 * Vk )/K * In - Rct ] * In2
3.1.4
Definition equivalence for common CTs
Since the only constants of a CT are its magnetizing curve, its Rct resistance and its
transformation ratio, it is possible to replace a transformer which Pn1 power in VA is of the
5PK1 type with a transformer which Pn2 power in VA is of the 5PK2 type.
Given that the values of Vs1 and Rct are known:
Vs1 = (Rct +Pn1/In2 )*K1 * In = (Rct + Pn2/In2 )*K2 *In
Pi = Rct * In2 (ohmic loss of CT)
(Pi +Pn1) * K1 = (Pi + Pn2 ) * K2
Hence K2 = [(Rct * In2 + Pn1 )/ (Rct * In2 + Pn2 )] * K1
3.1.5
How to calculate the knee-point voltage Vk of a CT defined in class P
•
For a transformer with accuracy class of 5P : Vs1/Vk = 1.6/1.4
Pn = [(1.6/1.4 * Vk )/K* In - Rct ] * In2
Hence Vk = 1.4/1.6 (Pn/In2 + Rct) K * In
•
For a transformer with a precision class 10P : Vs2/Vk = 1.9/1.4
Pn = [(1.9/1.4 * Vk )/K* In - Rct ] * In
2
Hence Vk = 1.4/1.9 (Pn/In2 + Rct) K * In.

Consumption of MiCOM P115 relays
The MiCOM P115's self- and dual-powered hardware versions (with identical ac burden at
their current inputs) have a minimum self-supply starting current of 0.2 In. This minimum
level of current is needed on at least one phase in order to enable the MiCOM relay to be
correctly self-powered and thus ensure the full capability of its protection functions:

Calculation of required CT for MiCOM P115
It is not possible to recommend any CT without detailed information. The decision needs to
be based on calculation.
AP
The following parameters have to be considered:
•
Type of CT (nominal power, nominal current and current ratio, internal resistance,
nominal accuracy limit factor, class and construction),
•
Resistance of wiring (length, cross section, specific resistance of material),
•
Resistance of P115 current inputs (as per table 2 in section 3.2).
Two critical cases have to be checked for different types of faults:
•
the lowest set current threshold value at which the relay has to operate (minimum
current).
•
the highest possible short-circuit current, which depends on the maximum short-circuit
power on the busbar of the substation (maximum current).
The following equation is used for dimensioning a current transformer:

POSSIBLE CONNECTIONS OF CTs AT THE P115's INPUT
Connection diagrams are given in the Installation chapter (P115/EN IN) of this manual.
4.1
Connection to 3 phase CTs + core balanced CT
4.1.1
Core balanced CT connected to the measurement earth current input (terminals 8 – 9)
This application can be used in systems with a small value of e/f current (isolated or with
Petersen coil). To ensure that the P115 is powered during earth fault conditions, the auxiliary
voltage supply should be connected to terminals 11 and 12 (Vx). Typically phase to phase ac
voltage from substation auxiliary transformer or VT is applied. For the above types of
system, the phase to phase voltage does not disappear during earth faults. For phase to
phase faults P115 is supplied from the CTs only.
Refer to Application chapter: P115/EN AP, Figure 4.
Advantage:
In this case, a typical core balanced CT can be used.
The earth fault current value has no influence on the CB tripping.
Disadvantage:
Additional Vx powering from an ac voltage source is required to trip in case of an e/f.
4.1.2
Core balanced CT connected to the self-powered earth current input (terminals 7 - 9)
Advantage:
This connection is advantageous when the transformation ratio of the core CT is less than
that of the phase CTs (greater sensitivity demand on the earth range). This enables the fault
at the earth current input of the protection to be perceived even if this fault is not of sufficient
level (0.2 In) to supply the protection via the phase currents, in which case the fault could
self-power the protection through the earth current input.
Disadvantage:
The core CT must be appropriately dimensioned, that is it must have few turns, to ensure
good sensitivity.
4.1.3
Connection to 2 phases CTs + core balanced CT
Refer to Application chapter: P115/EN AP, Figure 5.
Advantage:
Only 2 CTs are used, resulting in saving one phase CT. The third phase is reformed by the
wiring.
Disadvantage:
The phase and earth CTs must be suitably overdimensioned. The core CT must be
connected to the supply input of the earth current input (terminals 7 - 9).
We assume that the system is balanced.
4.2
The earth current input is connected to the summation of the 3 phase CTs
Refer to Application chapter: P115 EN AP, Figure 3.
Advantage:
In this case, the earth current is detected by summing the 3 phase currents, the use of a
core CT is therefore not required. The summing operation is performed at terminals 8 - 9 of
the earth current input.
It is not necessary to supply the relay via the earth current input. However, an additional
supply (shown Figure 3) via the earth fault current will provide more energy to the P115.
Therefore the CT starts supplying the P115 when the current drops below 0.2 Ien (refer to
the Technical Data chapter P115/EN TD).
Disadvantage:
Less sensitivity than the core CT connection.

MiCOM P115
AUXILIARY SUPPLY FUSE RATING
In the Safety section of this manual, the maximum allowable fuse rating of 16A is quoted. To
allow time grading with fuses upstream, a lower fuse link current rating is often preferable.
Use of standard ratings of between 6A and 16A is recommended. Low voltage fuse links,
rated at 250V minimum and compliant with IEC60269-2 general application type gG, with
high rupturing capacity are acceptable. This gives equivalent characteristics to HRC "red
spot" fuses type NIT/TIA often specified historically.
The table below recommends advisory limits on relays connected per fused spur. This
applies to the MiCOM P115, as these have inrush current limitation on switch-on, to
conserve the fuse-link.

1.1
Introduction
The P115 is equipped with integral fault recording facilities suitable for analysis of complex
system disturbances. Fault records can be read out by setting software MiCOM S1 via the
USB port accessible on the P115 front panel. The USB port offers a communications facility
to the P115.
Communications can be established via the USB port even if the P115 is supplied neither by
the CT nor by the auxiliary voltage.
Access to the USB port is protected by means of a plastic cover.
1.2
Event records
The relay records and time tags up to 100 events and stores them in non-volatile FRAM
memory. This enables the system operator to establish the sequence of events that
occurred within the relay following a particular power system condition, switching sequence
etc. When the available space is exhausted, the oldest event is automatically overwritten by
the most recent.
The real time clock within the relay provides the time tag for each event, to a resolution of
1 ms.
The event records are available for remote viewing, via the communications ports RS485 or
USB.
For extraction from a remote source via communications ports, refer to the SCADA
Communications section (P115/EN CT), where the procedure is fully explained.
Types of event
An event may be a change of state of a control input or output relay, a trip condition, etc.
The following sections show the various items that constitute an event:
Change of state of binary inputs
If one or more of the binary inputs has changed state since the last time that the protection
algorithm ran, the new status is logged as an event. The information is available if the event
is extracted and viewed via a PC.
Change of state of one or more output relay contacts
If one or more of the output relay contacts have changed state since the last time that the
protection algorithm ran, then the new status is logged as an event. The information is
available if the event is extracted and viewed via PC.
Relay alarm conditions
Any alarm conditions generated by the relays will also be logged as individual events.
The following table shows examples of some of the alarm conditions and how they appear in
the event list:
Alarm Condition
Event Text
Event Value
Auxiliary Supply Fail
Vx Fail ON/OFF
Bit position 0 in 32 bit field
CT Supply Fail
CT Supply Fail ON/OFF
Bit position 1 in 32 bit field
The above table shows the abbreviated description that is given to the various alarm
conditions and also a corresponding value between 0 and 31. This value is appended to
each alarm. It is used by the event extraction software, such as MiCOM S1, to identify the
alarm. Either ON or OFF is shown after the description to signify whether the particular
condition is operational or has reset.

Protection element trips
Any operation of protection elements,(a trip condition) will be logged as an event record,
consisting of a text string indicating the operated element and an event value. Again, this
value is intended for use by the event extraction software, such as MiCOM S1.
1.3
Fault records
Each fault record is generated with time stamp.
The following data is recorded for any relevant elements that operated during a fault, and
can be viewed in each of the last 5 fault records:
(i) Event Text (the reason for a trip):
Phase Overcurrent:
I> trip
I>> trip
I>>> trip
IN> trip
IN>> trip
Iasym> trip
CB Fail trip
AUX1 trip
AUX2 trip
CB Ext. trip (binary input configured to start the CB Fail logic)
(ii) Event Value:
Per phase record of the current value during the fault: Iϕ and measured IN
Fault records are stored in non-volatile memory (FRAM memory). This type of memory does
not require any maintenance (no battery inside the P115). Fault records are stored without
any time limitation even if the P115 is not supplied from any power source.
MR
1.4
Measurements
The relay produces a variety of directly measured power system quantities:
IA, IB, IC
-
RMS values
IN
-
measured fundamental harmonic only (E/F analogue input)
Iasym
-
calculated maximal difference between phase current and average value
from 3 phase current
The above quantities are used by the protection criteria and by the fault recorder.

INTRODUCTION
The MiCOM P115 feeder protection relays are fully numerical in design, implementing all
protection and non-protection functions in software. The relays employ a high degree of selfmonitoring. The commissioning tests do not need to be as extensive as with non-numeric
electronic or electro-mechanical relays.
In the commissioning of numeric relays, it is only necessary to verify that the hardware is
functioning correctly and that the application-specific software settings have been applied to
the relay. It is considered unnecessary to test every function of the relay if the settings have
been verified by one of the following methods:
•
Extracting the settings applied to the relay using appropriate setting software (preferred
method)
•
Via the operator interface
Unless previously agreed to the contrary, the customer will be responsible for determining
the application-specific settings applied to the relay and for testing of any scheme logic
applied by external wiring.
Blank commissioning test and setting records are provided at the end of this chapter for
completion as required.
Before carrying out any work on the equipment, the user should be
familiar with the contents of the safety guide SFTY/4L M/E11 or later
issue, or the safety and technical data section of the technical manual
and also the ratings on the equipment rating label.
For safety reasons, no work must be carried out on the P115 until all
power sources to the unit have been disconnected.

SETTING FAMILIARIZATION
When commissioning a MiCOM P115 relay for the first time, sufficient time should be
allowed to enable the user to become familiar with the method by which the settings are
applied.
The Getting Started chapter (P115/EN GS) contains a detailed description the P115 relay.
Via the front panel all the settings can be changed (refer to Settings chapter P115 /EN ST of
this manual), LEDs and alarms reset, and fault and event records cleared. However, menu
cells which have access levels higher than the default level will require the appropriate
password to be entered, before changes can be made.
Alternatively, if a portable PC is available together with suitable setting software (such as
MiCOM S1), the menu can be viewed a page at a time to display a full column of data and
text. This PC software also allows settings to be entered more easily, saved to a file on disk
for future reference or printed to produce a setting record. Refer to the PC software user
manual for details. If the software is being used for the first time, allow sufficient time to
become familiar with its operation.

PRODUCT CHECKS
These product checks cover all aspects of the relay and should be carried out to ensure that
the unit has not been physically damaged prior to commissioning, that it is functioning
correctly and that all input quantity measurements are within the stated tolerances.
If the application-specific settings have been applied to the relay prior to commissioning, it is
advisable to make a copy of the settings to allow their restoration later. This could be done
by:
4.1
•
Obtaining a setting file from the customer.
•
Extracting the settings from the relay itself (this again requires a portable PC with
appropriate setting software);
•
Manually creating a setting record. This could be done using a copy of the setting
record located at the end of this chapter to record the settings. As the relay’s menu is
scrolled through sequentially via the front panel user interface.
With the relay de-energized
The following group of tests should be carried out without powering the P115 and with the
trip circuit and flag indicator isolated.
The current transformer connections must be isolated from the relay for these
operations to be carried out.
WARNING:
NEVER OPEN CIRCUIT THE SECONDARY CIRCUIT OF A CURRENT
TRANSFORMER SINCE THE HIGH VOLTAGE PRODUCED MAY BE
LETHAL AND COULD DAMAGE INSULATION.
The line current transformers should be short-circuited and disconnected from the relay
terminals, using the isolating trip circuit and flag indicator provided. If this is not possible to
complete this operation, the wiring to these circuits must be disconnected and the exposed
ends suitably short circuited to prevent a safety hazard.
CM
4.1.1
Visual inspection
The rating information given under the top access cover on the front of the relay
should be checked. Check that the relay being tested is correct for the protected
line/circuit. Ensure that the circuit reference and system details are entered onto the
setting record sheet. Double-check the CT primary current rating, and be sure to
record the actual CT setting used.
Carefully examine the relay to check that no physical damage has occurred since
installation.
4.1.2
Insulation
Insulation resistance tests are only necessary during commissioning and if they have not
been performed during installation.
Isolate all wiring from the earth and test the insulation with an electronic or brushless
insulation tester at a dc voltage not exceeding 500V. Terminals of the grouped circuits
should be temporarily connected together.
The main groups of relay terminals are:
a)
Current transformer circuits,
b)
Trip coil and flag indicator outputs
c)
Auxiliary voltage supply
d)
Binary control inputs (L1 and L2: one circuit)
e)

4.1.3
External wiring
Check that the external wiring is correct when compared to the relevant relay and
scheme diagram. Ensure as far as practical that the phase sequence is as expected.
The relay diagram number appears on the rating label on the upper side of the case.
The connections should be checked against the scheme (wiring) diagram.
4.1.4
Auxiliary supply voltage (Vx)
The relay can be operated from either a dc only or ac/dc auxiliary supply depending on the
relay’s nominal supply rating. The incoming voltage must be within the operating range
specified in Table 1.
Without energizing the relay measure the auxiliary supply to ensure it is within the operating
range.
Nominal Supply Rating DC [AC rms]
DC Operating Range

Table 1:
Operational range of auxiliary supply Vx
It should be noted that the relay can withstand an ac ripple of up to 12% of the upper rated
voltage on the dc auxiliary supply.
Do not energize the relay or interface unit using the battery charger with the battery
disconnected as this can irreparably damage the relay’s power supply circuitry.
Energize the relay only if the auxiliary supply is within the specified operating ranges. If a
test block is provided, it may be necessary to link across the front of the test plug to connect
the auxiliary supply to the relay.
NOTE:

Vx nominal supply rating is common to auxiliary voltage supply and
binary control inputs
With the relay energized
The following group of tests verifies that the relay hardware and software are functioning
correctly and should be carried out while the P115 is powered.
MV isolators should be opened and the MV side should be connected to the earth to allow
safe operation of the CB.
4.2.1
Light emitting diodes (LEDs)
On power up the green LED should have lit up and stayed on indicating that the relay is
healthy. The relay has non-volatile memory which remembers the state (on or off) of the
alarm, trip and, if configured to latch, LED indicators when the relay was last energized from
an auxiliary supply. Therefore these indicators may also lit up when the auxiliary supply is
applied.
Latching of LEDs can be configured via MiCOM S1 setting software (USB port) or manually
by the front panel

Binary inputs
This test checks that all the binary inputs on the relay are functioning correctly.
The binary inputs should be energized one at a time, see external connection diagrams
(P115/EN IN) for terminal numbers.
The P115 has a display so it is possible to see the state of the binary inputs, by going to
theCOMMISSIONING/Opto I/P Status window in the menu, or by using MiCOM S1/S&R
Modbus/ Measurement Viewer software. Refer to the MiCOM S1 software user manual for
details.
If it is not possible to use Measuring Viewer software, it is necessary to check the binary
inputs by means of a functional test of the entire configuration.
Ensuring that the correct opto input nominal voltage is applied and correct polarity, connect
the field supply voltage to the appropriate terminals for the input being tested
NOTE:
The binary inputs may be energized from an external dc auxiliary
supply (e.g. the substation battery) in some installations. Check that
this is not the case before connecting the field voltage, otherwise
damage to the relay may result. If an external 24/27 V, 30/34 V,
48/54 V, 110/125 V, 220/250 V supply is being used it will be directly
connected to the relays optically isolated inputs . If an external supply
is being used then it must be energized for this test but only if it has
been confirmed that it is suitably rated with less than 12% ac ripple.
Default factory settings:
-
L1 binary input: not configured
-
L2 binary input: not configured

Output relays
To check output contacts it is necessary to carry out a functional test of the entire
configuration.
NOTE:
It should be ensured that thermal ratings of anything connected to the
output relays during the contact test procedure are not exceeded by
the associated output relay being operated for too long. It is therefore
advised that the time between application and removal of the contact
test is kept to the minimum.
Default factory settings:
-
RL1 output: Any Trip, no latching, no Reverse output logic
-

Reverse Output Logic means that after powering the P115, n/o contacts are closed. Output
triggering via a programmable function opens the contacts (rest position).
4.2.4
Rear communications port
This test should only be performed where the relay is to be accessed from a remote location
and will vary depending on the communications standard adopted.
It is not the intention of the test to verify the operation of the complete system from the relay
to the remote location, just the relay’s rear communications port and any protocol converter
necessary.

SETTING CHECKS
The setting checks ensure that all of the application-specific relay settings (i.e. the relay’s
functions), for the particular installation, have been correctly applied to the relay.
NOTE:
5.1
The trip circuit should remain isolated during these checks to prevent
accidental operation of the associated circuit breaker.
Apply application-specific settings
There are two methods of applying the settings to the relay:
Downloading them from a pre-prepared setting file to the relay using a portable PC running
the MiCOM S1 support software. Communication between the PC and the P115 is done via
the relay’s USB front port, located at the bottom of front panel, or rear communications port.
This method is preferred for transferring function settings as it is much faster and there is
less margin for error.
If a setting file has been created for the particular application and is available on an external
memory disk, this will further reduce the commissioning time.
Enter them manually via the relay’s operator interface.
Application notes for the setting values are given in Application Notes chapter P115/EN AP
of this manual.
5.2
Demonstrate correct relay operation
The above tests have already demonstrated that the relay is within calibration, thus the
purpose of these tests is as follows:
5.2.1
−
To determine that the primary protection functions of the relay, overcurrent, earth-fault
etc. can trip according to the correct application settings.
−
To verify the correct assignment of the CB trip outputs and of the flag indicator output,
by monitoring the response to a selection of fault injections.
Overcurrent protection testing
This test, performed on stage 1 of the overcurrent protection function, demonstrates that the
relay is operating correctly at the application-specific settings.
5.2.1.1
Connection and preliminaries
The testing current is fed via terminals: 1-2, 3-4, 5-6,7-8-9 connected to CTs. The type of
connection is shown in Figure 1. The external connection diagram is also available on the
front panel of P115.
Ensure that I> is configured to RL1 output.
NOTE:
The Low Energy Trip output and the Flag Indicator outputs are
activated by any protection elements set to trip.
Disconnect auxiliary voltage supply from P115 terminals 11 and 12.
Connect the trip output or flag indicator output so that its operation will trip the test set and
stop the timer.
NOTE:
During tripping, the trip and flag indicator outputs output energy on
terminals is::
-
trip coil output: 0.1 Ws 24 Vdc or 0.02 Ws 12 V (ordering option)
-
flag indicator output: 0.01 Ws 24 Vdc
The timer should be compatible with the above outputs.
Connect the current output of the test set to the “A” phase of the relay current transformer
input (terminals 1 and 2).

Ensure that the timer starts when the current is applied to the relay.
Figure 1: P115 external connection diagram
5.2.1.2
Perform the test
Ensure that the timer is reset.
Apply to the relay a current of twice the setting for I> to the relay (refer to chapter
P115/EN ST of this manual) and make a note of the time displayed when the chronometer
stops.
WARNING:
CM
5.2.1.3
NEVER OPEN CIRCUIT THE SECONDARY CIRCUIT OF A CURRENT
TRANSFORMER SINCE THE HIGH VOLTAGE PRODUCED MAY BE
LETHAL AND COULD DAMAGE INSULATION.
Check the operating time
Check that the operating time recorded by the timer is within the range shown in Table 2.
NOTES:
Except for the definite time characteristic, the operating times given in
Table 2 are for a time multiplier or time dial setting of 1. Therefore, to
obtain the operating time at other time multiplier or time dial settings,
the time given in Table 2 must be multiplied by the setting for IDMT
characteristics.
In addition, for definite time and inverse characteristics there is an
additional delay of up to 0.03 seconds that may need to be added to
the relay’s acceptable range of operating times.
If the P115 is not connected to an auxiliary voltage supply (Vx) it is
necessary to add an additional start-up time delay. The value of this
delay depends on the ratio: value current/0.2In. Refer to the
Application chapter of this manual (P115/EN AP) or the Technical
Data chapter of this manual (P115/EN TD)
For all characteristics, allowance must be made for the accuracy of
the test equipment being used.

5.2.1.4.1 CB coil output
Ensure that the CB coil is connected to terminals 29 (+) and 30 (-).
Ensure that I> stage is configured to trip (refer to chapter P115/EN ST of this manual)
Close the CB.
Connect a multimeter with recording of maximum dc voltage value to terminals 29 and 30.
Apply a current of twice the setting for I>.. The CB will open when the tI> time delay elapses.
Record the maximum voltage value measured by the multimeter. The value should be
greater than:
(i) 24 Vdc to 26.4 Vdc: for ordering option 24 Vdc 0.1 Ws
(ii) 12 Vdc to 13.2 Vdc: for ordering option 12 Vdc 0.02 Ws
P115 should trip CB.

Ensure that the Flag indicator is connected to terminals 27 (+) and 28 (-).
Reset the Flag indicator.
Connect a multimeter with recording of maximum dc voltage value to terminals 27 and 28.
Apply a current of twice the setting for I> . The Flag indicator will be triggered when the tI>
time delay elapses.
Record the maximum voltage value measured by the multimeter.
The value should be: 24 Vdc to 26.4 Vdc.
Flag indicator should be tripped.

MAINTENANCE
1.1
Maintenance period
It is recommended that products supplied by Schneider Electric receive periodic monitoring
after installation. In view of the critical nature of protective relays and their infrequent
operation, it is desirable to confirm that they are operating correctly, at regular intervals.
Schneider Electric protective relays are designed for a life in excess of 20 years.
MiCOM relays are self-monitoring and so require less maintenance than earlier designs of
relay. Most problems will set off an alarm so that remedial action can be taken. However,
some periodic tests should be carried out to ensure that the relay is functioning correctly and
that the external wiring is intact.
1.2
Maintenance checks
Although some functionality checks can be performed from a remote location by utilizing the
communications ability of the relays, these are predominantly restricted to checking that the
relay is measuring the applied currents accurately. Therefore it is recommended that
maintenance checks are performed locally (i.e. at the substation itself).
Before carrying out any work on the equipment, the user should be
familiar with the contents of the Safety Guide SFTY/4L M/E11 or later
issue, OR the safety and technical data section of the technical
manual and also the ratings on the equipment rating label.
For safety reasons, no work must be carried out on the P115 until
all power sources to the unit have been disconnected.
1.2.1
Binary Inputs
Binary inputs can be checked to ensure that the relay responds to its energization by
repeating the commissioning test detailed in section 4.2.2 of the Commissioning chapter
(P115/EN CM).
1.2.2
Outputs
The output relays can be checked to ensure that they operate by repeating the
commissioning test detailed in section 5.2.1.4 of the Commissioning chapter (P115/EN CM).
1.2.3
Measurement accuracy
If the power system is energized, the values measured by the relay can be compared with
known system values to check that they are in the approximate expected range.. If they are,
then the analogue/digital conversion and calculations are being performed correctly by the
relay. Suitable test methods can be found in sections 4.2.6 of the Commissioning chapter
(P115/EN CM).
Alternatively, the values measured by the relay can be checked against known values
injected into the relay via the test block, if fitted, or injected directly into the relay terminals.
These tests will prove the calibration accuracy is being maintained.

Method of repair
It is recommended that the P115 relay is returned to an Schneider Electric service centre for
repair.
Before carrying out any work on the equipment, the user should be
familiar with the contents of the Safety Guide SFTY/4L M/E11 or later
issue, OR the safety and technical data section of the technical
manual and also the ratings on the equipment rating label.
For safety reasons, no work must be carried out on the P115 until
all power sources to the unit have been disconnected.
1.4
Cleaning
Before cleaning the equipment ensure that all current transformers and voltage input
connections are isolated to prevent any possibility of an electric shock whilst cleaning.
The equipment may be cleaned using a lint-free cloth moistened with clean water.
The use of detergents, solvents or abrasive cleaners is not recommended as they may
damage the relay’s surface and leave a conductive residue.

MALOPERATION OF THE RELAY DURING TESTING
4.1
Failure of binary inputs
The binary inputs are configured in the SETTING GROUP1 (2)/INPUTS CONFIGURATION
column for each setting group. If an input does not appear to be recognized by the relay scheme
logic the COMMISSIONING/Opto I/P Status menu option can be used to verify whether the
problem is in the binary input itself or the mapping of its signal to the scheme logic functions. If the
binary input appears to be read correctly then it is necessary to examine its configuration.
Ensure the voltage rating for the opto inputs has been configured correctly with applied voltage. If
the binary input state is not read correctly by the relay the applied signal should be tested. Verify
the connections to the binary input using the correct wiring diagram. Next, using a voltmeter verify
that 80% opto setting voltage is present on the terminals of the binary input in the energized state.
If the signal is being correctly applied to the relay then the failure may be on the input card itself.
NOTE:
1. If the P115 is supplied by the USB port only, only part of the P115's
electronics (necessary to the communication facility) is supplied. From
this reason, the inputs' status is in high state (not dependent on the
voltage on the terminals). Any action pertaining to binary inputs is
blocked.
2. The COMMISSIONING /Opto I/P Status cell displays the logical state
of the inputs (not the presence of voltage on their terminals). For
example: if Vx is applied (high state) on the terminals of a binary input
and the Reverse Input Logic is set (function active in binary input low
state), the COMMISSIONING /Opto I/P Status cell displays the logical
state of the input as low (logical state after processing by the Reverse
Input Logic function)
4.2
Failure of output contacts
An apparent failure of the relay output contacts may be caused by the relay configuration; the
following tests should be performed to identify the real cause of the failure. Output testing can be
performed using the COMMISSIONING/Test outputs cell. When the command is executed the set
outputs (COMMISSIONING/Test Pattern) will be energized and will remain so for the duration of
the TOpen pulse (GLOBAL SETTINGS/ CIRCUIT BREAKER/ tOpen pulse min).
Test

Table 3:
Check
Is the Out of Service LED
illuminated?
Action
Illumination of this LED may indicate that the
relay is in test mode or that the protection
has been disabled due to a hardware verify
error (see Table 2).
Examine the Test outputs in the
Commissioning section of the
menu.
If the relevant bits of the contact status are
operated then proceed to test 4, if not
proceed to test 3.
Verify by examination of the fault
record whether the protection
element is operating correctly.
If the protection element does not operate verify
whether the test is being correctly applied.
Using the procedure described in
the Commissioning chapter
(P115/EN CM) energize every
output (note the correct external
connection diagram should be
consulted). A continuity tester can
be connected at the rear of the
relay for this purpose.
If the output relay operates then the problem
must be situated in the external wiring to the
relay. If the output relay does not operate
this could indicate a failure of the output
relay contacts (note that the self-tests verify
that the relay coil is being energized).
Ensure that the closed resistance is not too
high for the continuity tester to detect.
Failure of output contacts
If the protection element operates then it is
necessary to check the configuration, to
ensure that the configuration of the
protection element to the contacts is correct.

RECEIPT OF RELAYS
Upon receipt, relays should be examined immediately to ensure no external damage has
been sustained in transit. If damage has been sustained, a claim should be made to the
transport contractor and Schneider Electric should be promptly notified.
Relays that are supplied unmounted and not intended for immediate installation should be
returned to their protective polythene bags and delivery carton. Section 3 of P115/EN IN
gives more information about the storage of relays.
2.
HANDLING OF ELECTRONIC EQUIPMENT
A person’s normal movements can easily generate electrostatic potentials of several
thousand volts. Discharge of these voltages into semi-conductor devices when handling
electronic circuits can cause serious damage that, although not always immediately apparent
can reduce the reliability of the circuit. The relay’s electronic circuits are protected from
electrostatic discharge when housed in the case. Do not expose them to risk by removing
the front panel or printed circuit boards unnecessarily.
Each printed circuit board incorporates the highest practicable protection for its semiconductor devices. However, if it becomes necessary to remove a printed circuit board, the
following precautions should be taken to preserve the high reliability and long life for which
the relay has been designed and manufactured.
Before removing a printed circuit board, ensure that you are at the same electrostatic
potential as the equipment by touching the case.
Handle analog input modules by the front panel, frame or edges of the circuit boards.
Printed circuit boards should only be handled by their edges. Avoid touching the electronic
components, printed circuit tracks or connectors.
Do not pass the module to another person without first ensuring you are both at the same
electrostatic potential. Shaking hands achieves equipotential.
Place the module on an anti-static surface, or on a conducting surface that is at the same
potential as you.
If it is necessary to store or transport printed circuit boards removed from the case, place
them individually in electrically conducting anti-static bags.
In the unlikely event that you are making measurements on the internal electronic circuitry of
a relay in service, it is preferable that you are earthed to the case with a conductive wrist
strap. Wrist straps should have a resistance to ground between 500 kΩ to 10 MΩ. If a wrist
strap is not available you should maintain regular contact with the case to prevent a build-up
of electrostatic potential. Instrumentation which may be used for making measurements
should also be earthed to the case whenever possible.
More information on safe working procedures for all electronic equipment can be found in
BS EN 100015: Part 1:1992. It is strongly recommended that detailed investigations on
electronic circuitry or modification work should be carried out in a special handling area such
as described in the British Standard document.

MiCOM P115
STORAGE
If relays are not to be installed immediately upon receipt, they should be stored in a place
free from dust and moisture in their original cartons. Where de-humidifier bags have been
included in the packing they should be retained.
Care should be taken on subsequent unpacking that any dust, which has collected on the
carton, does not fall inside. In locations of high humidity the carton and packing may
become impregnated with moisture and the de-humidifier crystals will lose their efficiency.
Prior to installation, relays should be stored at a temperature of between –25˚C to +70˚C
(-13˚F to +158˚F).
4.
UNPACKING
Care must be taken when unpacking and installing the relays so that none of the parts are
damaged and additional components are not accidentally left in the packing or lost. Ensure
that any User’s CDROM or technical documentation is NOT discarded – this should
accompany the relay to its destination substation.
Relays must only be handled by qualified persons.
The site should be well lit to facilitate inspection, clean, dry and reasonably free from dust
and excessive vibration.
5.
RELAY MOUNTING
Individual relays are normally supplied with an outline diagram showing the dimensions.
This information can also be found in the product publication.
Wall-mounting only is available.
The relay is mounted onto a panel by means of four:
-
4.5mm ∅ drill holes: flush mounting case
-
5.5mm ∅ drill holes: wall mounting case
Detailed drawing with all measurements can be found in Figure 1.

RELAY WIRING
Before carrying out any work on the equipment, the user should be
familiar with the contents of the Safety Guide SFTY/4L M/E11 or later
issue, OR the safety and technical data section of the technical
manual and also the ratings on the equipment rating label.
For safety reasons, no work must be carried out on the P115 until all
power sources to the unit have been disconnected.
The measuring current inputs of the P115 should be connected to the secondary wires of the
power system CTs as shown in the connection diagrams in section 8. ” External Connection

Tripping the CB using energy from a tripping transfomer
Design of the Main Current Transformers
The main current transformer load is composed essentially of the P115’s power
consumption, the consumption of the supply conductors wiring, and, in the event of
transformer current tripping, the consumption of the tripping transformer that is normally
short-circuited on the secondary side. In the event of transformer current tripping the
maximum load occurs during closing of the tripping device. The CT requirements of the P115
are given in the technical data chapter. When selecting the main current transformers one
should keep in mind that the impedances of the protection device and of the tripping
transformer decrease when the current increases, due to saturation. The current
transformers rating matching the overcurrent factor and the short-circuit withstand capability
can be based on the corresponding low loads. These main current transformers can be
considerably overburdened in the nominal current range even when the fault does not
exceed the accuracy class rating. Typically, main current transformers having a nominal
power rating of 15 VA 10 P10 or 30 VA10 P5 should be provided, but in any case, the
required parameters of the main current transformers must be defined as a result of
calculation analysis (refer to Application chapter: P115/EN AP).
Connecting the Tripping Transformers
The measured variable is fed into the P115 through the primary winding of the tripping
transformer, WA 25 O. During fault-free operation the secondary side of the tripping
transformer is short-circuited via one of the P115’s contacts. In the event of a trip the contact
opens and the circuit breaker is actuated (see Figures 6 to 9).
9.2
Tripping CB using energy provided by an external capacitor unit
Connecting an E124 Capacitor Trip Unit
The MiCOM E124 capacitor trip unit is an auxiliary device typically used to provide energy to
the trip coil of a circuit breaker in distribution systems. The trip unit can be used in all cases
where a battery and charger would otherwise be necessary to trip the circuit breaker. Such is
the case in substations where there is no auxiliary supply, and where protection relays draw
their auxiliary power from current and voltage transformer circuits. The easiest way to store
the energy for trip coils is in a capacitor trip unit (see Figure 11).
Serially connected with a protection relay, it will release its full energy (300V / 59J) to the trip
coil upon closure of the relay's trip contact.
E124 auxiliary supply: 48-230Vac or 48-250Vdc.
E124 key features:
IN
•
Extended autonomy (over 8 days without recharge)
•
- Two independent capacitor banks, monitored by a microprocessor to guarantee two
consecutive trips at maximum power (300V / 59J) without recharge
•
Connection in parallel possible to control the trip coil if it requires more than 59J.
•
Available output power: 118J (2*59J)
•
Output impedance (per capacitor bank): 10 Ohms
•
Capacitance: two capacitor banks of 1320 μF each
•
Power consumption to charge the capacitors (under 100V): <5 VA or 2.5W
•
Power consumption when the capacitors are charged (under 100V): <1.5 VA or 0.25 W
NOTE:
The current leads should be connected exactly as shown in Figures 7
to 10.

MiCOM P115 relay can communicate by a RS 485 link behind the unit following the
MODBUS RTU protocol.
2.1
Technical characteristics of the MODBUS connection
2.1.1
Parameters of the MODBUS connection
The different parameters of the MODBUS connection are as follows:
•
Isolated two-point RS485 connection (2kV 50Hz)
•
MODBUS line protocol in RTU mode
•
Communication speed can be configured by an operator dialog in the front panel of the
relay:
Baud rate
4800
9600
38400
57600
115200
Transmission mode of the configured characters by operator dialog:
Mode
1 start / 8 bits / 1 stop: total 10 bits
1 start / 8 bits / even parity / 1 stop: total 11 bits
1 start / 8 bits / odd parity / 1 stop: total 11 bits
1 start / 8 bits / 2 stop: total 11 bits
2.1.2
Synchronisation of exchanges messages
All character received after a silence on the line with more or equal to a transmission time of
3 characters is considered as a firm start.
2.1.3
Message validity check
The frame validity is working with a cyclical redundancy code CRC with 16 bits. The
generator polynomial is:
1 + x² + x15 + x16 = 1010 0000 0000 0001 binary = A001h

Messages validity check
When MiCOM P115 relay receive a master query, it validates the frame:
•
If the CRC is false, the frame is invalid. MiCOM P115 relay do not reply to the query. The
master must retransmit its query. Excepting a broadcast message, this is the only case
of non-reply by MiCOM P115 relay to a master query.
•
If the CRC is good but the MiCOM relay can not process the query, it sends an exception
response.

2.4.13.1 Calculation formula for phase current values
Line phase current value (primary value) = phase sampled value (e.g. word 10, 11, 12 or 13)
* {line primary CT ratio (address 0120h)/Line CT sec (address 0121h)} A/10.
2.4.13.2 Calculation formula for earth current values
The formula depends of nominal earth current:
0.01 to 2 Ien and 0.05-10Ien range
Line earth current value (primary value) = earth sampled value (e.g. word 10 or 14) * {line
primary CT ratio (address 0122h)/Line CT sec (address 0123h)} A/1000.
0.2 to 40 Ien range
Line earth current value (primary value) = earth sampled value (e.g. word 10 or 14) * {line
primary CT ratio (address 0122h)/Line CT sec (address 0123h)} A/10.

IEC60870-5-103 INTERFACE
The IEC60870-5-103 interface is a master/slave interface with the relay as the slave device.
This protocol is based on the VDEW communication protocol. The relay conforms to
compatibility level 2, compatibility level 3 is not supported.
The following IEC60870-5-103 facilities are supported by this interface:
3.1
•
Initialisation (Reset)
•
Time Synchronisation
•
Event Record Extraction
•
General Interrogation
•
Cyclic Measurements
•
General Commands
Physical connection and link layer
Connection is available for IEC60870-5-103 through the rear RS485 port. It is possible to
select both the relay address and baud rate using the front panel interface. Following a
change, a reset command is required to re-establish communications.
The parameters of the communication are the following:
3.2
•
Even Parity
•
8 Data bits
•
1 stop bit
•
Data rate 9600 or 19200 bauds
Initialisation
Whenever the relay has been powered up, or if the communication parameters have been
changed a reset command is required to initialise the communications. The relay will
respond to either of the two reset commands (Reset CU or Reset FCB), the difference being
that the Reset CU will clear any unsent messages in the relay's transmit buffer.
The relay will respond to the reset command with an identification message ASDU 5, the
Cause Of Transmission COT of this response will be either Reset CU or Reset FCB
depending on the nature of the reset command. The following information will be contained
in the data section of this ASDU:
Manufacturer Name:
Schneider Electric
The Software Identification Section will contain the first four characters of the relay model
number to identify the type of relay, eg P115.
In addition to the above identification message, if the relay has been powered up it will also
produce a power up event.
CT
3.3
Time synchronisation
The relay time and date can be set using the time synchronisation feature of the IEC608705-103 protocol. The relay will correct for the transmission delay as specified in IEC60870-5103. If the time synchronisation message is sent as a send/confirm message then the relay
will respond with a confirm. Whether the time synchronisation message is sent as a send
confirm or a broadcast (send/no reply) message, a time synchronisation message will be
returned as Class 1 data.

(CT) 13-35/40
Spontaneous events
The events created by the relay will be passed using the standard function type/information
numbers to the IEC60870-5-103 master station. Private codes are not used, thus any events
that cannot be passed using the standardised messages will not be sent.
Events are categorised using the following information:
•
Common Address
•
Function Type
•
Information number
3.10-3.14 contains a complete listing of all events produced by the relay. The common
address is used to differentiate in circumstances where the relay produces more events of a
certain type than can be passed using the standardised messages. For example if the relay
produces starts and trips for three stages of overcurrent only two stages can be passed
using the standardised messages.
Using the different common address for two of the overcurrent stages allows each stage to
be indicated. 3.10-3.14 shows the common address as an offset value. The common
address offset will be added to the station address in order to pass these events.
3.5
General interrogation
The GI request can be used to read the status of the relay, the function numbers, information
numbers and common address offsets that will be returned during the GI cycle are indicated
in 3.10-3.14.
3.6
Cyclic measurements
The relay will produce measured values using ASDU 9 on a cyclical basis, this can be read
from the relay using a Class 2 poll (note ADSU 3 is not used).
It should be noted that the measurands transmitted by the relay are sent as a proportion of
2.4 times the rated value of the analogue value. The selection of 2.4 for a particular value is
indicated in 3.10-3.14.
3.7
Commands
A list of the supported commands is contained in 3.10-3.14. The relay will respond to other
commands with an ASDU 1, with a cause of transmission (COT) of negative
acknowledgement of a command.
3.8
Disturbance records
The relay does not support a facility for disturbance records in the Monitor direction.IEC
60870-5-103 DATABASES.
3.9
Blocking of monitor direction
The relay does not support a facility to block messages in the Monitor direction.IEC 60870-5103 DATABASES.
3.10
Spontaneous messages managed by MiCOM P115
These messages includes a sub-assembly of events which are generated on the relay,
because some generated events are not registered in VDEW. They are the most priority
messages.
An event is always generated on the rising edge of the information.
Some events can be generated on the rising or lowering edge.
In the list below, events only generated on rising edge will be tagged with a ‘*’.

Processed Commands
System Commands: Availability
Synchronization Command (ASDU 6): FUN<255>,INF <0>; TYP <6>;COT<8>
This command can be sent to a specific relay, or global. The time sent by master is the time
of the first bit of the frame. The relay synchronizes with this time, corrected by the frame
transmission delay. After updating its time, the relay send back an acknowledge to the
master, by giving its new current time.
This acknowledge message will be an event of ASDU 6 type.
General Interrogation Initialization command (ASDU 7):
FUN<255>;INF <0>;TYP <7>; COT<9>
This command starts the relay interrogation:
The relay then sends a list of data containing the relay state (see list described above).
The GI command contains a scan number which will be included in the answers of the GI
cycle generated by the GI command.
If a data has just changed before extracted by the GI, the new state is sent to the master
station.
When an event is generated during the GI cycle, the event is sent in priority, and the GI cycle
is temporarily interrupted. The end of the GI consists in sending an ASDU 8 to the master
station.
If, during a General Interrogation cycle, another GI Initialization command is received, the
precedent answer is stopped, and the new GI cycle started.
General Commands (ASDU 20) (Control direction): Availability
•
LEDs Reset: This command acknowledge all alarms on Front Panel on MiCOM P115
products:
FUN<160>;INF<19>, TYP<20>, COT <20>,<ADDR>
•
Setting group number 1: FUN<160>;INF<23>, TYP<20>, COT <20>,<ADDR>
•
Setting group number 2: FUN<160>;INF<24>, TYP<20>, COT <20>,<ADDR>
•
Trip TC: FUN<168>;INF <1>; TYP <20>; COT<20>,<ADDR>
•
Close TC: FUN<168>;INF <2>; TYP <20>; COT<20>,<ADDR>
After executing one of these commands, the relay sends an acknowledge message, which
contains the result of command execution.
If a state change is the consequence of the command, it must be sent in a ASDU 1 with COT
12 (remote operation).
CT
If the relay receive another command message from the master station before sending the
acknowledge message, it will be discarded.
Commands which are not processed by the relay are rejected with a negative acknowledge
message.

Relay re initialization
In case of relay re initialization, the relay send to the master station: Availability
A message indicating relay start/restart (FUN<160>;INF <5>; TYP <5> COT <5>) or a
message indicating Reset CU (FUN<160>;INF <5>; TYP <3> COT <4>) or a message
indicating Reset FCB (FUN<160>;INF <5>; TYP <2> COT <3>).
Each identification message of the relay (ASDU 5) contains the manufacturer name in 8
ASCII characters et 4 free characters containing: «P115 ».
3.14
Cyclic Messages (ASDU9)
Only measurands can be stored in these messages.
The measurands values are stored in lower levels of communication, before polling by
master station.
Several of the fields in the ASDU 9 (FUN<160>,INF <148>) and ASDU 3
(FUN<160>,INF<147>) are unused in the P115 relay. Only Ia, Ib, Ic values are stored (with
a rate such as: 2,4 * nominal value = 4096).
