Aconsistentdesignofoffersfrom All Merlin Gerin offers are designed according
toelectrical,mechanicalandcommunication
Medium Voltage to Low Voltage
consistencyrules.
Theproductsexpressthisconsistencybytheir
overalldesignandsharedergonomics.
Electricalconsistency:
Each product complies with or enhances system performance at co-ordination level:
breaking capacity, Isc, temperature rise, etc. for more safety, continuity of supply
(discrimination) or economic optimisation (cascading).
The leading edge technologies employed in Merlin Gerin’s Guiding System ensure
high performance levels in discrimination and cascading of protection devices,
electrodynamic withstand of switches and current distributors, heat loss of devices,
distribution blocks and enclosures.
Likewise , inter-product ElectroMagnetic Compatibilty (EMC) is guaranteed.
Discrimination guarantees co-ordination between the operating
characteristics of serial-connected circuit-breakers. Should
a fault occurs downstream, only the circuit-breaker placed
immediately upstream from the fault will trip.
Mechanical consistency:
Each product adopts dimensional standards simplifying and optimising its use within
the system.
It shares the same accessories and auxiliaries and complies with global ergonomic
choices (utilisation mode, operating mode, setting and configuration devices, tools,
etc.) making its installation and operation within the system a simpler process.
Direct connection of the Canalis KT busbar trunking on the
Masterpact 3200 A circuit breaker.
Communicationconsistency:
Thanks to the use of standard Web technologies, you can offer
your customers intelligent Merlin Gerin switchboards allowing
easy access to information: follow-up of currents, voltages,
powers, consumption history, etc.
Each product complies with global choices in terms of communication protocols
(Modbus, Ethernet, etc.) for simplified integration in the management, supervision
and monitoring systems.

Communication
All Sepam relays communicate and can be
integrated in a communication architecture.
All Sepam information can be accessed
remotely.
Twotypesofcommunicationnetwork
Sepam relays can be connected to two types of networks, thus providing access to
different types of information:
ba supervisory local area network or S-LAN
ban engineering local area network or E-LAN.
Examples of communication architectures are presented on pages 36 and 37.
Supervisory local area network (S-LAN)
DE53103
1
Communicationnetworksand
protocols
An S-LAN is used for supervision functions concerning the installation and the
electric network. It can be used to connect a set of communicating devices using the
same communication protocol to a centralized supervision system.
Sepam can be connected to an S-LAN using one of the following communication
protocols:
bModbus RTU
bModbus TCP/IP
bDNP3
bIEC 60870-5-103
bIEC 61850
Engineering local area network (E-LAN)
Sepam connection to two communication networks (S-LAN and
E-LAN).
An E-LAN is intended for Sepam parameter-setting and operating functions. It can be
used to connect a set of Sepam units to a PC running the SFT2841 software.
In this configuration, the operator has remote and centralized access to all Sepam
information, with no need to develop any special communication software.
The operator can easily:
bset up the Sepam general parameters and functions
bcollect all Sepam operating and diagnostics information
bmanage the protection system for the electric network
bmonitor the status of the electric network
brun diagnostics on any incidents affecting the electric network.
Communicationprotocols
Modbus RTU
Modbus RTU is a data-transmission protocol, a de facto standard since 1979 widely
used in industry and accepted by many communicating devices.
For more information on the Modbus RTU protocol, visit www.modbus.org.
Modbus TCP/IP
The Modbus TCP/IP communication protocol offers the same functions as Modbus
RTU as well as compatibility with multi-master architectures
DNP3
DNP3 is a data-transmission protocol specially suited to the needs of distributors for
remote control/monitoring of substations in the electric network.
For more information on the DNP3 protocol, visit www.dnp.org.
IEC 60870-5-103
IEC 60870-5-103 is an accompanying standard for the standards in the
IEC 60870-5 series. It defines communication between protection devices and the
various devices in a control system (supervisor or RTU) in a substation.
For more information on the IEC 60870-5-103 protocol, visit www.iec.ch.
IEC 61850
The standards in the IEC 61850 series define a protocol for communication in
electrical substations. The Ethernet-based protocol offers advanced characteristics
and interoperability between multi-vendor devices.
The Sepam relay handles the station bus, in compliance with standards IEC 618506, 7-1, 7-2, 7-3, 7-4 and 8-1.
For more information on the IEC 61850 protocol, visit www.iec.ch.

Communication
Communicationnetworksand
protocols
Otherprotocols
A gateway / protocol converter must be used to connect Sepam to a communication
network based on other protocols.
IEC 60870-5-101
The CN1000 gateway developed by EuroSystem enables Sepam connection to
IEC 60870-5-101 networks.
This gateway is quick and simple to implement using the supplied configuration
software integrating all Sepam parameters.
For more information on the CN1000 gateway, visit www.euro-system.fr.

Implementation
Acompleterangeofaccessories
Sepam connects to a communication network via a communication interface.
Selection of the interface depends on the communication architecture:
bnumber of networks to be connected:
v1 network, S-LAN or E-LAN
v2 networks, S-LAN and E-LAN
bcommunication protocol selected for the S-LAN: Modbus RTU, DNP3,
IEC 60870-5-103 or IEC 61850
bnetwork physical interface:
v2-wire or 4-wire RS485
vEthernet
vfiber optic, with star or ring architecture.
Sepam communication interfaces are presented in detail on page 179.
DirectSepamconnectiontotheEthernetnetwork
A complete range of Sepam communication interfaces
Sepam series 40 and Sepam series 80 units can be directly connected to the
Ethernet network via the ACE 850 communication interface. In this way they make
full use of Ethernet network performance and all IEC 61850 functions.
bCompatible communication protocols:
vModbus TCP/IP
vIEC 61850
bNetwork physical interface:
v10 baseT /100 base TX (star architecture)
v100 base FX (star architecture).
Easyimplementation
PE80033-36
The communication interfaces are remote modules that are easy to install and
connect.
The SFT2841 software is used for complete setup of the communication interfaces:
bprotocol selection and setup of the functions specific to each protocol
bsetup of the physical interface.
Advanced configuration of IEC 61850 protocol
The SFT850 software is used for advanced configuration of the IEC 61850 protocol
for both the ECI850 server and the ACE850 communication interface:
bcomplete Sepam-configuration database (.icd)
bprocessing of system-configuration files (.scd)
bcreation and processing of ECI850 and ACE850 configuration files (.cid).
Sepam IEC 61850 server
The entire Sepam range can be connected to an IEC 61850 system via the Sepam
ECI850 server, representing the most economical solution.
The server also ensures compatibility with the E-LAN network.
PE0
Ethernet gateways in a Modbus environment
Sepam can be connected to an Ethernet TCP/IP network in a totally transparent
manner via the EGX100 gateway or the EGX400 server.
EGX100gateway
The EGX100 offers access to enhanced communication and multi-master
architectures. It provides IP (Internet Protocol) connection for communication on all
types of networks, notably intranets and internet.
EGX400server
Access to Sepam information via a web browser.
In addition to Ethernet TCP/IP connection, the EGX400 offers a web server and
HTML pages designed specially to present the essential Sepam information.
This information may be accessed in clear text and at no risk on any PC connected to
the intranet/internet and equipped with a web browser.

Metering and diagnosis
The values measured by Sepam that may be remote accessed are divided into the
following categories:
bmeasurements: currents, voltages, frequency, power, temperatures, etc.
benergy: calculated or pulse-type energy counters
bnetwork diagnosis: phase displacement, tripping currents, unbalance ratio, etc.
bmachine diagnosis: temperature rise, motor starting time, remaining operating
time before overload tripping, waiting time after tripping, etc.
bswitchgear diagnosis: cumulative breaking current, operating time and number of
operations, circuit breaker charging time, etc.
bSepam diagnosis: partial or major fault, etc.
bLogipam counters.
Remoteindications
The logic-state information that may be remote accessed are divided into the
following categories:
balarms and internal status conditions
bstatus of logic inputs
bstatus of logic outputs
bstatus of nine LEDs on the front panel of Sepam
bstatus of logic-equation output bits.
Alarmsandinternalstatusconditions
The alarms and internal status conditions are remote indications (TS) pre-assigned
to protection and control functions.
Remote indications depend on the type of Sepam and can be re-assigned by
Logipam.
The remote indications that can be accessed via the communication link include:
ball protection-function alarms
bmonitoring-function alarms: CT or VT fault, control fault
bSepam status data:
vSepam not reset
vremote setting inhibited, remote-control orders inhibited
bstatus data on the following functions:
vrecloser: in service / inhibited, reclosing in progress / successful, permanent trip
vdisturbance recording: records inhibited / stored.

Sepam
Pulse-typeremote-controlorders
Pulse-type remote-control orders (TC) may be carried out in two modes (selected by
parameter setting):
bdirect mode
bconfirmed SBO (select before operate) mode.
Remote-control orders are pre-assigned to metering, protection and control functions
and depend on the type of Sepam.
They are used for the following, in particular:
bto control breaking device opening and closing
bto reset Sepam and initialize peak-demand measurements
bto select the active group of settings by enabling group A or B
bto inhibit or enable the following functions: recloser, thermal overload protection,
disturbance recording.
Remote-control orders can be re-assigned by Logipam.
Remote-controlsecurity
Transmission of Sepam series 80 remote controls and settings over a Modbus
S-LAN can be password protected.

Time-tagging
Time-taggedevents
The time-tagging function assigns a date and precise time to status changes (events)
so that they can be accurately organized over time.
Sepam systematically time-tags the following events:
bstatus changes of all logic inputs
bstatus changes of all remote indications (TS - alarms and internal status
conditions).
Each event is time-tagged to within one millisecond.
1
The number of stacks of time-tagged events managed by Sepam on each
communication port and the volume of each stack in terms of the numbers of events
depend on the communication protocol used.

configuration
Whatever the communication protocol used, Modbus RTU, DNP3, IEC 60870-5-103
or IEC 61850 events may be used by a remote monitoring and control system for
data logging and histories, for example.
Unsollicitedevents
Using the DNP3 and IEC 61850 protocols, Sepam can spontaneously transmit timetagged events to the supervisor. The transmission of unsollicited events must be
activated during setup.
Time-settingandsynchronization
The Sepam internal clock manages the date and time.
Time-setting is possible:
bvia the Sepam display
busing the SFT2841 software
bvia the communication link.
To ensure long-term time stability or to coordinate a number of devices, Sepam units
can be synchronized:
bby an external pulse to a dedicated logic input
bvia the communication link.

Metering and diagnosis
Description
Metering
Sepam is a precision metering unit.
All the metering and diagnosis data used for commissioning and required
for the operation and maintenance of your equipment are available locally
or remotely, expressed in the units concerned (A, V, W, etc.).
Phasecurrent
RMS current for each phase, taking into account harmonics up to number 13.
Different types of sensors may be used to meter phase current:
b1 A or 5 A current transformers
bLPCT type current sensors.
2
Residualcurrent
Two residual current values are available depending on the type of Sepam and
sensors connected to it:
bresidual currents I0S, calculated by the vector sum of the 3 phase currents
bmeasured residual current I0.
Different types of sensors may be used to measure residual current:
bCSH120 or CSH200 specific core balance CT
bconventional 1 A or 5 A current transformer
bany core balance CT with an ACE990 interface.
Demandcurrentandpeakdemandcurrents
Demand current and peak demand currents are calculated according to the 3 phase
currents I1, I2 and I3:
bdemand current is calculated over an adjustable period of 5 to 60 minutes
bpeak demand current is the greatest demand current and indicates the current
drawn by peak loads.
Peak demand currents may be cleared.
Voltage and frequency
The following measurements are available according to the voltage sensors
connected:
bphase-to-neutral voltages V1, V2, V3
bphase-to-phase voltages U21, U32, U13
bresidual voltage V0
bpositive sequence voltage Vd and negative sequence voltage Vi
bfrequency f.
Power
Powers are calculated according to the phase currents I1, I2 and I3:
bactive power
breactive power

bpower factor (cos j).
Power calculations is based on the 2 wattmeter method.
The 2 wattmeter method is only accurate when there is no residual current and it is
not applicable if the neutral is distributed.
Peakdemandpowers
The greatest demand active and reactive power values calculated over the same
period as the demand current.
The peak demand powers may be cleared.
Energy
b4 accumulated energies calculated according to voltages and phase currents I1, I2
and I3 measured: active energy and reactive energy in both directions
b1 to 4 additional accumulated energy meters for the acquisition of active or reactive
energy pulses from external meters.
Temperature

Sepamself-diagnosis
Switchgear diagnosis data give facility managers information on:
bmechanical condition of breaking device
bSepam auxiliaries
and assist them for preventive and curative switchgear maintenance actions.
The data are to be compared to switchgear manufacturer data.
ANSI 60/60FL - CT/VT supervision
Used to monitor the entire metering chain:
bCT and VT sensors
bconnection
bSepam analog inputs.
Monitoring includes:
bconsistency checking of currents and voltages measured
bacquisition of phase or residual voltage transformer protection fuse blown
contacts.
In the event of a loss of current or voltage measurement data, the assigned
protection functions may be inhibited to avoid nuisance tripping.
Internalfailure
Two categories of internal failures are monitored:
bmajor failures: Sepam shutdown (to fail-safe
position).
The protection functions are inhibited, the output relays
are forced to drop out and the “Watchdog” output
indicates Sepam shutdown
bminor failures: downgraded Sepam operation.
Sepam’s main functions are operational and equipment
protection is ensured.
ANSI 74 - Trip circuit supervision
To detect trip circuit circuit failures, Sepam monitors:
bshunt trip coil connection
bmatching of breaking device open/closed position contacts
bexecution of breaking device open and close orders.
The trip circuit is only supervised when connected as shown below.
Detectionofpluggedconnectors
The system checks that the current or voltage sensors
are plugged in. A missing connector is a major failure.
The system checks that the optional modules
configured are present and working correctly.
The absence or failure of a remote module is a minor
failure, the absence or failure of a logic input/output
module is a major failure.

tripping or failed fault tripping
bput Sepam in fail-safe position to avoid any unwanted
operation
balert the facility manager of the need for maintenance
operations.
Connection for shunt trip coil
monitoring.
Connection for undervoltage
trip coil monitoring.

Six cumulative currents are proposed to assess breaking device pole condition:
btotal cumulative breaking current
bcumulative breaking current between 0 and 2 In
bcumulative breaking current between 2 In and 5 In
bcumulative breaking current between 5 In and 10 In
bcumulative breaking current between 10 In and 40 In
bcumulative breaking current > 40 In.
Each time the breaking device opens, the breaking current is added to the cumulative
total and to the appropriate range of cumulative breaking current.
Cumulative breaking current is given in (kA)².

before allowing the busbar supplying the machines to
be re-energized, to avoid electrical and mechanical
transients.
ANSI 27 - Undervoltage
Protection of motors against voltage sags or detection
of abnormally low network voltage to trigger automatic
load shedding or source transfer.
Works with phase-to-phase voltage (Sepam series

ANSI 81R - Rate of change of frequency
Protection function used for fast disconnection of a generator or load shedding
control. Based on the calculation of the frequency variation, it is insensitive to
transient voltage disturbances and therefore more stable than a phase-shift

Disconnection
In installations with autonomous production means connected to a utility, the “rate of
change of frequency” protection function is used to detect loss of the main system in
view of opening the incoming circuit breaker to:
bprotect the generators from a reconnection without checking synchronization
bavoid supplying loads outside the installation.
Load shedding
The “rate of change of frequency” protection function is used for load shedding in
combination with the underfrequency protection to:
beither accelerate shedding in the event of a large overload
bor inhibit shedding following a sudden drop in frequency due to a problem that
should not be solved by shedding.
Detection of insulation faults by measuring residual
voltage in isolated neutral systems.

Controlandmonitoring
Description
Sepam performs all the control and monitoring functions required for electrical
network operation:
bthe main control and monitoring functions are predefined and fit the most frequent
cases of use. They are ready to use and are implemented by simple parameter
setting after the necessary logic inputs / outputs are assigned.
bthe predefined control and monitoring functions can be adapted for particular
needs using the SFT2841 software, which offers the following customization options:
vcustomization of the control matrix by changing the assignment of output relays,
LEDs and annunciation messages
vlogic equation editor, to adapt and complete the predefined control and monitoring
functions (Sepam series 40 only)
vcreation of personalized messages for local annunciation (Sepam series 40 only).
2
Operatingprinciple
DE52789
The processing of each control and monitoring function may be broken down into
3 phases:
bacquisition of input data:
vresults of protection function processing
vexternal logic data, connected to the logic inputs of an optional MES114 input /
output module
vremote control orders (TC) received via the Modbus communication link
bactual processing of the control and monitoring function
butilization of the processing results:
vactivation of output relays to control a device
vinformation sent to the facility manager:
- by message and/or LED on the Sepam display and SFT2841 software
- by remote indication (TS) via the Modbus communication link.
Logic inputs and outputs
The number of Sepam inputs / outputs must be adapted to fit the control and
monitoring functions used.
The 4 outputs included in the Sepam base unit (series 20 or series 40) may be
extended by adding one MES114 modules with 10 logic inputs and 4 output relays.
After selecting the MES114 type required by an application, the logic inputs must be
assigned to functions. The functions are chosen from a list which covers the whole
range of possible uses. The functions are adapted to meet needs within the limits
of the logic inputs available. The inputs may also be inverted for undervoltage type
operation.
A default input / output assignment is proposed for the most frequent uses.

Controlandmonitoring
Description of predefined functions
Each Sepam contains the appropriate predefined control and monitoring functions
for the chosen application.
ANSI 94/69 - Commande disjoncteur/contacteur
Control of breaking devices equipped with different types of closing and tripping coils:
bcircuit breakers with shunt or undervoltage trip coils
blatching contactors with shunt trip coils
The function processes all breaking device closing and tripping conditions, based on:
bprotection functions
bbreaking device status data
bremote control orders
bspecific control functions for each application (e.g. recloser).
The function also inhibits breaking device closing, according to the operating
conditions.
2
With Sepam series 20, it is necessary to use an MES114 module in order to have all
the required logic inputs.
ANSI 86 - Latching / acknowledgement
The tripping outputs for all the protection functions and all the logic inputs can be
latched individually. The latched information is saved in the event of an auxiliary
power failure.
(The logic outputs cannot be latched.)
All the latched data may be acknowledged:
reset
blocally, with the
key
bremotely via a logic input
bor via the communication link.
The Latching/acknowledgement function, when combined with the circuit breaker/
contactor control function, can be used to create the ANSI 86 “Lockout relay”
function.
ANSI 68 - Logic discrimination
This function provides:
bperfect tripping discrimination with phase-to-phase and phase-to-earth shortcircuits, on all types of network
bfaster tripping of the breakers closest to the source (solving the drawback of
conventional time discrimination).
Each Sepam is capable of:
bsending a blocking input when a fault is detected by the phase overcurrent and
earth fault protection functions, which may or may not be directional (ANSI 50/51,
50N/51N, 67 or 67N/67NC)
band receiving blocking inputs which inhibit protection tripping. A saving mechanism
ensures continued operation of the protection in the event of a blocking link failure.
Outputrelaytesting
Each output relay is activated for 5 seconds, to make it simpler to check output
connections and connected switchgear operation.

Description
Metering
Peakdemandpowers
Sepam is a precision metering unit.
All the metering and diagnosis data used for
commissioning and required
for the operation and maintenance of your equipment
are available locally
or remotely, expressed in the units concerned (A, V, W,
etc.).
Phasecurrent
3
RMS current for each phase, taking into account
harmonics up to number 13.
Different types of sensors may be used to meter phase
current:
b1 A or 5 A current transformers
bLPCT type current sensors.
Residualcurrent
Four types of residual current values are available
depending on the type of Sepam and sensors
connected to it:
b2 residual currents I0Σ and I’0Σ, calculated by the
vector sum of the phase currents
b2 measured residual currents I0 and I’0.
Different types of sensors may be used to measure
residual current:
bCSH120 or CSH200 specific core balance CT
bconventional 1 A or 5 A current transformer with
CSH30 interposing ring CT
bany core balance CT with an ACE990 interface.
The greatest demand active and reactive power values calculated over the same
period as the demand current. The peak demand powers may be cleared.
Energy
b4 accumulated energies calculated according to voltages and phase currents I1, I2
and I3 measured: active energy and reactive energy in both directions
b1 to 4 additional accumulated energy meters for the acquisition of active or reactive
energy pulses from external meters.
Temperature
Accurate measurement of temperature inside equipment fitted with Pt100, Ni100
or Ni120 type RTDs, connected to the optional remote MET148-2 module.
Rotationspeed
Calculated by the counting of pulses transmitted by a proximity sensor at each
passage of a cam driven by the rotation of the motor or generator shaft.
Acquisition of pulses on a logic input.
Phasordiagram
A phasor diagram is displayed by SFT2841 software and the mimic-based UMI
to check cabling and assist in the setting and commissioning of directional and
differential protection functions.
According to the connected sensors, all current and voltage information can be
selected for display in vector form.
Demandcurrentandpeakdemand
currents
Demand current and peak demand currents are
calculated according to the 3 phase currents I1, I2 and
I3:
bdemand current is calculated over an adjustable
period of to 0 minutes
bpeak demand current is the greatest demand current
and indicates the current drawn by peak loads.
Peak demand currents may be cleared.
Voltage and frequency
The following measurements are available according to
the voltage sensors connected:
bphase-to-neutral voltages V1, V2, V3 and V’1, V’2,
V’3
bphase-to-phase voltages U21, U32, U13 and U’21,
U’32, U’13
bresidual voltage V0, V’0 or neutral point voltage Vnt
bpositive sequence voltage Vd, V’d and negative
sequence voltage Vi, V’i
bfrequency measured on the main and additional
voltage channels.
Power
Powers are calculated according to the phase currents
I1, I2 and I3:
bactive power
breactive power
bapparent power
bpower factor (cos φ).
According to the sensors used, power calculations may
be based on the 2 or 3 wattmeter method.
The 2 wattmeter method is only accurate when there is
no residual current and it is not applicable if the neutral
is distributed.
The 3 wattmeter method gives an accurate calculation
of 3-phase and phase by phase powers in all cases,
regardless of whether or not the neutral is distributed.

ANSI 27R - Remanent undervoltage
Protection used to check that remanent voltage
sustained by rotating machines has been cleared
before allowing the busbar supplying the machines to
be re-energized, to avoid electrical and mechanical
transients.
ANSI 27 - Undervoltage
Protection of motors against voltage sags or detection
of abnormally low network voltage to trigger automatic
load shedding or source transfer.
Works with phase-to-phase or phase-to-neutral
voltage, each voltage being monitored separately.
Characteristics
bdefinite time (DT) curve
bIDMT curve.
Detection of abnormally high frequency compared to the rated frequency, to monitor
power supply quality.
ANSI 81L - Underfrequency
Detection of abnormally low frequency compared to the rated frequency, to monitor
power supply quality.
The protection may be used for overall tripping or load shedding.
Protection stability is ensured in the event of the loss of the main source and
presence of remanent voltage by a restraint in the event of a continuous decrease of
the frequency, which is activated by parameter setting.
ANSI 81R - Rate of change of frequency
Protection function used for fast disconnection of a generator or load shedding
control. Based on the calculation of the frequency variation, it is insensitive to
transient voltage disturbances and therefore more stable than a phase-shift
protection function.
Disconnection
In installations with autonomous production means connected to a utility, the "rate of
change of frequency" protection function is used to detect loss of the main system in
view of opening the incoming circuit breaker to:
bprotect the generators from a reconnection without checking synchronization
bavoid supplying loads outside the installation.

Load shedding
The "rate of change of frequency" protection function is used for load shedding in
combination with the underfrequency protection to:
beither accelerate shedding in the event of a large overload
bor inhibit shedding following a sudden drop in frequency due to a problem that
should not be solved by shedding.
ANSI 59 - Overvoltage

Phase-to-phaseandphase-to-earthshort-circuitprotection
Each unit has 2 groups of settings, A and B, to adapt the settings to suit the network
configuration.
The active group of settings (A or B) is set by a logic input or the communication link.
Example of use: normal / backup mode network
bgroup A for network protection in normal mode, when the network is supplied by the
utility
bgroup B for network protection in backup mode, when the network is supplied by a
backup generator.

Examplesofuse:
btransformers: switching of groups of settings by logic input, according to
transformer ventilation operating mode, natural or forced ventilation (ONAN or
ONAF)
bmotors: switching of groups of settings according to current set point, to take into
account the thermal withstand of motors with locked rotors.
Measurement origin
DE51775
The measurement origin needs to be indicated for each unit of the protection
functions that may use measurements of different origins.
The setting links a measurement to a protection unit and allows the protection units to
be distributed optimally among the measurements available according to the sensors
connected to the analog inputs.
Example:distribution of ANSI 50N/51N function units for transformer earth fault
protection:
b2 units linked to measured I0 for transformer primary protection
b2 units linked to measured I'0 for transformer secondary protection
b2 units linked to I0S for protection upstream of the transformer
b2 units linked to I'0S for protection downstream of the transformer.

Controlandmonitoring
Description
Sepam performs all the control and monitoring functions required for electrical
network operation:
bthe main control and monitoring functions are predefined and fit the most frequent
cases of use. They are ready to use and are implemented by simple parameter
setting after the necessary logic inputs / outputs are assigned.
bthe predefined control and monitoring functions can be adapted for particular
needs using the SFT2841 software, which offers the following customization options:
vlogic equation editor, to adapt and complete the predefined control and monitoring
functions
vcreation of personalized messages for local annunciation
vcreation of personalized mimic diagrams corresponding to the controlled devices
vcustomization of the control matrix by changing the assignment of output relays,
LEDs and annunciation messages
bwith the Logipam option, Sepam can provide the most varied control and
monitoring functions, programmed using the SFT2885 programming software that
implements the Logipam ladder language.
Operatingprinciple
The processing of each control and monitoring function may be broken down into
3 phases:
bacquisition of input data:
vresults of protection function processing
vexternal logic data, connected to the logic inputs of an optional MES120 input /
output module
vlocal control orders transmitted by the mimic-based UMI
vremote control orders (TC) received via the Modbus communication link
bactual processing of the control and monitoring function
butilization of the processing results:
vactivation o sent to the facility manager:
- by message and/or LED on the Sepam display and SFT2841 software
- by remote indication (TS) via the Modbus communication link
- by real-time indications on device status on the animated mimic diagram.

PE09
Logic inputs and outputs
The number of Sepam inputs / outputs must be adapted to fit the control and
monitoring functions used.
The 5 outputs included in the Sepam series 80 base unit may be extended by adding
1, 2 or 3 MES120 modules with 14 logic inputs and 6 output relays.
After the number of MES120 modules required for the needs of an application is set,
the logic inputs are assigned to functions. The functions are chosen from a list which
covers the whole range of possible uses. The functions are adapted to meet needs
within the limits of the logic inputs available. The inputs may also be inverted for
undervoltage type operation.
A default input / output assignment is proposed for the most frequent uses.
Maximum Sepam series 80 configuration with 3 MES120
modules: 42 inputs and 23 outputs.

Controlandmonitoring
Description of predefined functions
Each Sepam contains the appropriate predefined control and monitoring functions
for the chosen application.
ANSI 94/69 - Circuit breaker/contactor control
Control of breaking devices equipped with different types of closing and tripping coils:
bcircuit breakers with shunt or undervoltage trip coils
blatching contactors with shunt trip coils
bcontactors with latched orders.
The function processes all breaking device closing and tripping conditions, based on:
bprotection functions
bbreaking device status data
bremote control orders
bspecific control functions for each application (e.g. recloser, synchro-check).
The function also inhibits breaking device closing, according to the operating
conditions.
Automatic transfer (AT)
3
This function transfers busbar supply from one source to another. It concerns
substations with two incomers, with or without coupling.
DE51889
The function carries out:
bautomatic transfer with a break if there is a loss of voltage or a fault
bmanual transfer and return to normal operation without a break, with or without
synchro-check
bcontrol of the coupling circuit breaker (optional)
bselection of the normal operating mode
bthe necessary logic to ensure that at the end of the sequence, only 1 circuit breaker
out of 2 or 2 out of 3 are closed.
The function is distributed between the two Sepam units protecting the two incomers.
The synchro-check function (ANSI 25) is carried out by the optional MCS025 module,
in conjunction with one of the two Sepam units.
Load shedding - Automatic restart
Automatic load regulation on electrical networks by load shedding followed by
automatic restarting of motors connected to the network
Load shedding
Automatic transfer with synchro-check controlled by
Sepam series 80.
The breaking device opens to stop motors in case of:
detection of a network voltage sag by the positive sequence undervoltage protection
function ANSI 27D
receipt of a load shedding order on a logic input.
Automaticrestart
The motors disconnected as a result of the network voltage sag are automatically
restarted:
bafter the return of network voltage is detected by the positive sequence
undervoltage protection function ANSI 27D
band a time delay has run out, so as to stagger motor restarts.
De-excitation
Interruption of a synchronous generator’s excitation supply and tripping of the
generator breaking device in case of:
bdetection of an internal generator fault
bdetection of an excitation system fault
breceipt of a de-excitation order on a logic input or via the communication link.

Gensetshutdown
Shutdown of the driving machine, tripping of the breaking device and interruption of
the generator excitation supply in case of:
bdetection of an internal generator fault
breceipt of a genset shutdown order on a logic input or via the communication link.
Controlofcapacitorbanks
This function controls 1 to 4 switches for capacitor steps, taking into account all the
closing and tripping conditions determined by the ANSI 94/69 function for control of
the switchgear.
Manual or automatic control, controlled by an external reactive-energy regulator.
ANSI 68 - Logic discrimination
This function provides:
bperfect tripping discrimination with phase-to-phase and phase-to-earth shortcircuits, on all types of network
bfaster tripping of the breakers closest to the source (solving the drawback of
conventional time discrimination).
Each Sepam is capable of:
bsending a blocking input when a fault is detected by the phase overcurrent and
earth fault protection functions, which may or may not be directional (ANSI 50/51,
50N/51N, 67 or 67N/67NC)
band receiving blocking inputs which inhibit protection tripping. A saving mechanism
ensures continued operation of the protection in the event of a blocking link failure.
3
ANSI 86 - Latching / acknowledgement
The tripping outputs for all the protection functions and all the logic inputs can be
latched individually. The latched information is saved in the event of an auxiliary
power failure.
(The logic outputs cannot be latched.)
All the latched data may be acknowledged:
blocally, with the key reset
bremotely via a logic input
bor via the communication link.
The Latching/acknowledgement function, when combined with the circuit breaker/
contactor control function, can be used to create the ANSI 86 "Lockout relay"
function.
Outputrelaytesting
Each output relay is activated for 5 seconds, to make it simpler to check output
connections and connected switchgear operation.

Removablememorycartridge
Sepam series 80 memory cartridge and backup battery.
The cartridge contains all the Sepam characteristics:
ball Sepam protection and parameter settings
ball the metering and protection functions required for the application
bpredefined control functions
bfunctions customized by control matrix or logic equations
bfunctions programmed by Logipam (optional)
bpersonalized local-control mimic diagram
baccumulated energies and switchgear diagnosis values
bworking languages, customized and otherwise.
It may be made tamper-proof by lead sealing.
It is removable and easy to access on the front panel of Sepam to reduce
maintenance time.
If a base unit fails, simply:
bswitch off Sepam and unplug connectors
bretrieve original cartridge
breplace the faulty base unit by a spare base unit (without cartridge)
bload the original cartridge into the new base unit
bplug in the connectors and switch Sepam on again:
Sepam is operational, with all its standard and customized functions, without
requiring any reloading of protection and parameter settings.

Backupbattery
Standard lithium battery, 1/2 AA format, 3.6 Volts.
It allows the following data to be stored in the event of an auxiliary power outage:
btime-tagged event tables
bdisturbance recording data
bpeak demands, tripping context, etc
bdate and time.
The battery presence and charge are monitored by Sepam.
The main data (e.g. protection and parameter settings) are saved in the event of an
auxiliary power outage, regardless of the state of the battery.
Auxiliarypowersupply
DC power supply voltage from 24 to 250 V DC.
Fiverelayoutputs
The 5 relay outputs O1 to O5 on the base unit must be connected to connector
A . Each output can be assigned to a predetermined function using the SFT2841
software.
O1 to O4 are 4 control outputs with one NO contact, used by default for the
switchgear control function:
bO1: switchgear tripping
bO2: switchgear closing inhibition
bO3: switchgear closing
bO4: available.
O5 is an indication output used by default for the watchdog function and has two
contacts, one NC and one NO.

Available functions
The availability of certain protection and metering functions depend on the phase and
residual voltages measured by Sepam.
The table below gives the voltage input connection variants for which for each
protection and metering function dependent on measured voltages is available.
Example:
The directional overcurrent protection function (ANSI 67N/67NC) uses residual
voltage V0 as a polarization value.
It is therefore operational in the following cases:
bmeasurement of the 3 phase-to-neutral voltages and calculation of
V0Σ (3 V + V0Σ, variant 1)
bmeasurement of residual voltage V0 (variant 5).
The protection and metering functions which do not appear in the table below are
available regardless of the voltages measured.

The logic equation editor included in the SFT2841 software can be used to:
bcomplete protection function processing:
vadditional interlocking
vconditional inhibition/validation of functions
vetc.
badapt predefined control functions: particular circuit breaker or recloser control
sequences, etc.
Note that the use of the logic equation editor excludes the possibility of using the
Logipam programming software.
SFT2841: logic equation editor.
A logic equation is created by grouping logic input data received from:
bprotection functions
blogic inputs
blocal control orders transmitted by the mimic-based UMI
bremote control orders
using the Boolean operators AND, OR, XOR, NOT, and automation functions such as
time delays, bistables and time programmer.
Equation input is assisted and syntax checking is done systematically.
The result of an equation may then be:
bassigned to a logic output, LED or message from the control matrix
btransmitted by the communication link, as a new remote indication
butilized by the circuit breaker/contactor control function to trip, close or inhibit
breaking device closing
bused to inhibit or reset a protection function.

bin the SFT2841 “Alarms” and “Alarm History” screens.
Local-control mimic diagram (Sepam series 80)
PE0
The local-control mimic diagram displayed on the UMI can be personalized by
adapting one of the supplied, predefined mimic diagrams or by creating a diagram
from scratch.
The mimic-diagram editor can be used to:
bcreate a fixed, bitmap background (128 x 240 pixels) using a standard drawing tool
bcreate animated symbols or use predefined animated symbols to represent the
electrotechnical devices or other objects
bassign the logic inputs or internal status conditions that modify the animated
symbols. For example, the logic inputs for the circuit-breaker position must be linked
to the circuit-breaker symbol to enable the display of the open and closed conditions
bassign the logic outputs or internal status conditions that are activated when an
opening or closing order are issued for the symbol
bdisplay the current, voltage and power measurements on the mimic diagram.

Function
The SFT850 software is used to easily create, modify and consult the SCL
(Substation Configuration Language) configuration files for the IEC 61850
communication protocol:
bCID (Configured IED description) file for configuration of a device connected to an
IEC 61850 network
bSCD (Substation Configuration Description) file for IEC 61850 configuration of
substation equipment.
The SFT850 software supplements the standard IEC 61850 configuration created
with the SFT2841 software in cases where the configuration must be precisely
adapted to system requirements.
Addingordeletingequipment
The SFT850 software can be used to add or delete connected equipment in the IEC
61850 configuration. If a Sepam unit is added, the software uses the supplied ICD
(IED capability description) file to start configuration.

badd, modify or delete RCBs (Report Control Block). A Report Control Block defines
dataset transmission conditions
badd, modify or delete GCBs (Goose Control Block). A Goose Control Block defines
how data is exchanged between Sepam units
bmodify dead measurement bands. This parameter is used to optimise
communication in that measurements are transmitted only if they have changed
significantly.

Logic input / output assignment
ofSepamseries20
The use of the preset control and monitoring functions requires exclusive parameter
setting and particular wiring of the inputs according to their application and the type
of Sepam.
The advanced UMI or the SFT2841 software may be used to assign inputs and set
the control and monitoring function parameters.
Since an input may only be assigned to a single function, not all the functions are
available at the same time.
Example: if the logic discrimination function is used, the switching of groups of
settings function may not be used.

Selectionguide
4 remote modules are proposed as options to enhance the Sepam base unit
functions:
bthe number and type of remote modules compatible with the base unit depend on
the Sepam application
bthe DSM303 remote advanced UMI module is only compatible with base units that
do not have integrated advanced UMIs.

MCS025
Synchro-checkmodule
Function
PE0
The MCS025 module checks the voltages upstream and downstream of a circuit
breaker to ensure safe closing (ANSI 25).
It checks the differences in amplitude, frequency and phase between the two
measured voltages, taking into account dead line/busbar conditions.
Three relay outputs may be used to send the close enable to several
Sepam series 80 units.
The circuit-breaker control function of each Sepam series 80 unit will take this close
enable into account.
The settings for the synchro-check function and the measurements carried out by the
module may be accessed by the SFT2841 setting and operating software, similar to
the other settings and measurements for the Sepam series 80.
The MCS025 module is supplied ready for operation with:
bthe CCA620 connector for connection of the relay outputs and the power supply
bthe CCT640 connector for voltage connection
bthe CCA785 cord for connection between the module and the Sepam series 80
base unit.

If the value exceeds 3 kV, it is necessary to add an Rl surge limiter in parallel with the
relay and stabilizing resistor in order to protect the CTs (see: surge limiter).
Protectionsensitivity
The CTs consume magnetizing current and the surge limiter, when installed, creates
fault current. The minimum residual primary current detected by the protection is
therefore:
Id = n x (im1+…imp + if + is)

b im1, …imp are read on the CT magnetization curves at V = Rs x is
b if is the total earth leakage current of the surge limiter for Vs = Rs x is, i.e. the sum
of the earth leakage currents of the N limiter units installed in parallel: if = N x ib
(see: surge limiter).
Surgelimiter
If the calculations have shown that it is necessary to install a surge limiter in parallel
with the relay and Rs to protect the CTs, it is determined as follows.
Choice
Standardreferences
bthe surge limiters on offer consist of limiter blocks which are independent of each
other. Each block accepts a maximum current of 40 A RMS for 1 s. By installing the
blocks in parallel, it is possible to obtain the appropriate limiter for the application.
bthere are two standard references:
va single module, comprising one block
va triple module, comprising three independent blocks which are aligned.
Calculationofthenumberofblocksperphase
According to i, max. RMS short-circuit current in the secondary winding of a CT, the
number of blocks required per phase is calculated:
bfor a three-phase relay, N triple modules should be ordered
bfor a single-phase relay, N blocks, made up of triple and single modules.

ACE969TP and ACE969FO
Interfacesnetwork
The ACE969 multi-protocol communication interfaces are for Sepam series 20,
Sepam series 40 and Sepam series 80.
They have two communication ports to connect a Sepam to two independent
communication networks:
bThe S-LAN (Supervisory Local Area Network) port is used to connect Sepam to a
communication network dedicated to supervision, using one of the three following
protocols:
vIEC 60870-5-103
vDNP3
vModbus RTU.
The communication protocol is selected at the time of Sepam parameter setting.
bThe E-LAN (Engineering Local Area Network) port, reserved for Sepam remote
parameter setting and operation using the SFT2841 software.
There are two versions of the ACE969 interfaces, which are identical except for the
S-LAN port:
bACE969TP (Twisted Pair), for connection to an S-LAN network using a 2-wire
RS 485 serial link
bACE969FO (Fiber Optic), for connection to an S-LAN network using a fiber-optic
connection (star or ring).
The E-LAN port is always a 2-wire RS485 type port.

RS 232 / RS 485 converter
Function
PE00
The ACE909-2 converter is used to connect a master/central computer equipped
with a V24/RS 232 type serial port as a standard feature to stations connected
to a 2-wire RS 485 network.
Without requiring any flow control signals, after the parameters are set, the
ACE909-2 converter performs conversion, network polarization and automatic
dispatching of frames between the master and the stations by two-way simplex
(half-duplex, single-pair) transmission.
The ACE909-2 converter also provides a 12 V DC or 24 V DC supply for the
distributed power supply of the Sepam ACE949-2, ACE959 or ACE969 interfaces.
The communication settings should be the same as the Sepam and supervisor
communication settings.

Connection
DE51682
ConnectionofcorebalanceCT
Only one core balance CT can be connected to the ACE990 interface.
The secondary circuit of the MV core balance CT is connected to 2 of the 5 ACE990
interface input terminals. To define the 2 input terminals, it is necessary to know the
following:
bCore balance CT ratio (1/n)
bCore balance CT power
bClose approximation of rated current In0
(In0 is a general setting in Sepam and defines the earth fault protection setting
range between 0.1 In0 and 15 In0).
The table below can be used to determine:
bThe 2 ACE990 input terminals to be connected to the MV core balance CT
secondary
bThe type of residual current sensor to set
bThe exact value of the rated residual current In0 setting, given by the following
formula: In0 = k x number of core balance CT turns
with k the factor defined in the table below.
The core balance CT must be connected to the interface in the right direction for
correct operation: the MV core balance CT secondary output terminal S1 must be
connected to the terminal with the lowest index (Ex).

Kvalue
Example:
Given a core balance CT with a ratio of 1/400 2 VA, used within
a measurement range of 0.5 A to 60 A.
How should it be connected to Sepam via the ACE990?
1. Choose a close approximation of the rated current In0,
i.e. 5 A.
2. Calculate the ratio:
approx. In0/number of turns = 5/400 = 0.0125.
3. Find the closest value of k in the table opposite to
k = 0.01136.
4. Check the mininum power required for the core balance CT:
2 VA core balance CT > 0.1 VA V OK.
5. Connect the core balance CT secondary to ACE990 input
terminals E2 and E4.
6. Set Sepam up with:
In0 = 0.01136 x 400 = 4.5 A.
This value of In0 can be used to monitor current between
0.45 A and 67.5 A.
