The setpoint is operated when the actual phase sequence does not match the indicated
normal phase rotation.
The actual frequency range is 45.00 - 65.00 Hz.
When the 4LN3 or 3LN3 wiring mode is selected, the voltages will be line-to-neutral; for
any other wiring mode, they will be line-to-line voltages.
The Device Fault trigger is active when the self-diagnostics test detects a critical
(unrecoverable) error. This could happen when a corrupted configuration setup or
incompatible setup setting is detected. In this event, the device will reset the corrupted
setup to default. The trigger is cleared when the setup is rewritten or device diagnostics
is cleared either through the Status Information Menu (see Section 7.1), or through
communications. When a non-critical error is detected, the device will only set a
corresponding fault bit in the self-check diagnostics register and restart operations.

Chapter 4 Setup Menus
The No-Volt trigger is intended for the use as a fast setpoint override condition for PFC
operations in order to protect the capacitor banks against voltage interruptions. When
used with the Hard Switch-Off action, it can de-energize the output relays in
approximately 25 ms. This avoids bringing the still charged capacitors back after the
voltage is restored. When used with other setpoint actions, this trigger can provide the
response time to alarm conditions at 25-75 ms.
The Uncompensated reactive power trigger is active when the device fails to bring the
power factor or reactive power into the target setpoint range.

When a setpoint is operated, its status is always stored to the alarm status register
even if no action is assigned to the setpoint. The alarm status register can be polled
and cleared through communications.
This action causes the alarm LED on the front panel to light, giving the user a local
alarm indication. The alarm LED operates in latched mode, i.e., even if an alarm
condition disappears, the alarm LED continues to operate until the user acknowledges
the alarm from the front panel (see Section 5.1). An alarm LED can be operated from
any number of setpoints using an OR scheme.
These actions are intended for the use with the PFC alarm protection setpoints in order
to protect the capacitor banks against harmful conditions that can cause damage.
When an alarm override condition is detected, the Hard Switch-Off action immediately
switches out all the capacitor banks including those defined as permanently switched
in. When used with the No-Volt trigger condition (see Note
to Table 4-7), this action
provides the fastest possible response to voltage interruptions.
The Soft Switch-Off action switches off the capacitor banks progressively in pre-set
disconnection intervals, as long as the alarm condition is present. This allows escaping
the over-voltage or high harmonics conditions with minimum required cycling of the
capacitor banks. The capacitor banks that are defined as permanently switched in will
Chapter 4 Setup Menus
31
not be affected. After the alarm condition passes, the PFC will return to automatic
operation after the safety delay which is 50 times the power factor setpoint operate
delay (see Note to Table 4-11).
The Stop action freezes the PFC operations in automatic operation modes. The PFC
avoids any automatic switching operations on the capacitor banks while the alarm
condition is present. This action does not affect operations in the Manual/Remote mode.
Alarm relays operate in unlatched mode. This means that a relay is operated while an
alarm condition is present and is automatically released when an alarm condition
disappears. Each relay can be operated from any number of setpoints using an OR
scheme, i.e., a relay will be operative while either of the alarm conditions is still present.
This action converts a common-use event counter to the dedicated time counter that
measures time at 0.1-hour resolution while the setpoint is operative. Each time counter
has a non-volatile shadow counter that counts time at 1-second resolution before the
corresponding time counter is incremented. The time counters can be inspected via the
Status Information Menu. They are labeled by an hour mark in the middle window.

This menu allows you to set the relay operation mode: non-failsafe or failsafe.
Failsafe relay operation is the opposite of normal operation where relay contacts
are closed when a relay is operated (activated), and are open when a relay is
released (de-activated). In failsafe mode, an alarm is activated by a nonenergized relay which will open in all cases when an alarm condition is present or
an alarm setpoint is not operational either due to a loss of control power or due to
corruption of the setpoint setup configuration. A failsafe relay is closed only if it is
under setpoint control and no alarm conditions exist, or if it is manually operated
from the front panel or via communications.

When the PFC is programmed to operate with two setpoint ranges, the active setpoint
range is selected by the external contact status through the instrument's digital input:
open = SP1, closed = SP2 setpoint range. To sense an external contact status, the
digital input should be configured as a status input (see Section 4.3).
Nominal voltage is shown in units of Volts as a whole number, or in kVolts with two
decimal places.
These parameters appear only if setpoint SP2 is selected as an operational setpoint.
Setting this parameter to 'On' forces a capacitor bank to be permanently switched in
when the PFC is put into an operation mode, and to be switched out when the PFC
shuts down, following all switching and re-close time delays. The permanently switched
banks continue under PFC protection but are not involved into either switching program.
This delay is also used in automatic operation modes as the reference restoration time
when an alarm setpoint override condition takes place followed by the soft release of
the capacitor banks (see Section 4.6). When the alarm condition is no longer present,
the PFC will delay restoration of the automatic switching program for an amount of time
equal to 50 times the power factor setpoint operate delay. This prevents excess cycling
in over-voltage and high harmonics conditions.
NOTES:
1. The PFC setup parameters, except the operation mode, are protected from being
changed while the PFC is running. Ensure that the PFC is OFF before configuring setup
parameters. To disable protection after shutting the PFC down, exit the setup menu,
and then re-enter the menu once more.
2. The PFC may not be put in operation mode if no capacitor banks are specified in the
PFC setup either as controlled or permanently switched banks.
3. The power rating values for the capacitor banks are not allowed to be in descending
order. Each capacitor bank must have the same or higher power value than the
previous bank. When entering the bank powers, the starting value is prompted at equal
to the power of the previous bank and is not permitted to drop below this value.
Chapter 4 Setup Menus
41
4. The target power factor limits are always specified for the I and IV quadrants regardless
of the location of the instrument on the source or load side. The PFC will automatically
account for the direction of power flow providing full four-quadrant operation.
5. If both target power factor limits are specified for the same quadrant, the high power
factor limit should never be less than the low limit. If the target limits are being set for
two quadrants, the lagging (inductive) power factor should be specified as the low limit
and the leading (capacitive) one as the high target limit. Whenever these relations are
not fulfilled, the instrument will automatically adjust the high target power factor to the
low target limit.

Chapter 5 PFC Setup and Operation
5. PFC Setup and Operation
This chapter describes how to setup the Power Factor Controller for your
application and explains its important features. Brief instructions are included for
certain setup and display operations. Complete setup instructions are found in
Section 4.13, PFC Setup; complete display information is found in Chapter 6
(Data Display) and Chapter 7 (Viewing Status Information).
5.1 Capacitor Bank Control Options
The C192PF8-RPR offers you three options to control capacitor banks in order to
meet the conditions of your electrical equipment and avoid unnecessary
switching. All options may be used at the same time when applied to different
banks.
Automatic Control
This option puts the banks under full PFC control and allows them to be used in
either a manual or automatic PFC switching program.
To put the capacitor bank under PFC control, specify the bank size in kvar to allow for
manual or automatic bank switching (see Section 4.13, PFC Setup).
Manual Control
This option allows some of the banks to be manually switched in using direct
control over the output relays. You can use this option for checking or repairing
capacitor banks.
This option does not use the PFC to control the capacitor banks. Switching is
done outside the PFC by directly forcing the output relays from the front panel
(see Section 4.12, Manual Relay Control Menu) or via communications. The
switched in banks remain connected until they are disconnected manually.
The size of the capacitor banks intended for direct manual control should be set to none
(see Section 4.13, PFC Setup), thus moving them out of the PFC control.
Since the PFC does not manage the capacitor banks, and forcing the output
relays also overrides the common alarm setpoint conditions, neither PFC setpoint
protection nor common alarm setpoints can be used to protect the capacitor
banks against harmful alarm conditions. This should be done separately, outside
the C192PF8-RPR.
Permanently Switched (Non-Programmable) Banks
This option allows some of the banks to be automatically switched in whenever
the PFC is put into operation and to remain permanently connected any time the
PFC is operating. This option is intended to avoid excess cycling of the capacitor
banks that draw near their cycling limit, or to put constant capacitive load onto the
network to avoid non-necessary switching.
44
Chapter 5 PFC Setup and Operation
To specify the bank as a permanently switched bank, set the bank size parameter to On
(see Section 4.13, PFC Setup).
The permanently switched banks are switched in automatically when the PFC is
put into either manual or automatic operation mode and before a switching
program begins, and are switched out when the PFC shuts down, following all
switching and re-connection time delays. These banks remain under PFC
protection but are not involved into either switching program (assumed to be nonprogrammable banks).
5.2 PFC Operation
5.2.1 Modes of Operation
The PFC can operate in three control modes: self-adapting automatic mode,
optimizing automatic mode, and manual mode. Both automatic modes provide
automatic power factor (in Power Factor Controller mode) or reactive power (in
Reactive Power Regulator mode) correction whereby the PFC automatically
accounts for deficient or excessive reactive power and makes necessary
adjustments.
Self-adapting Automatic Mode (Auto 1)
Self-adapting mode is a simple automatic operation mode suitable to most
applications. The PFC switches in additional banks when the measured power
factor lags against the target power factor or the measured reactive power is over
the high target kvar (excessive inductive load is detected), and switches out
redundant banks when the measured power factor leads against the target power
factor limits or the measured reactive power is under the low target kvar
(excessive capacitive load is detected).
The capacitor banks are switched in and switched out progressively, always
starting from the low-size bank available at this step, following the pre-set
switching and re-connection delays.
The self-adapting program is complete when one of the following is true:
1. The measured power factor (in PFC mode) or kvar (in RPR mode) attains the
pre-set PFC setpoint range.
2. In PFC mode, the deviation from the target power factor is less than 0.7 of
the smallest size bank.
Automatic Optimization Mode (Auto 2)
This is a highly optimized operation mode that provides minimum switching
operations. At each step, the PFC accounts for deficient inductive or capacitive
reactive power to attain the target power factor or target kvar and selects the
exact combination of the banks among those presently available that requires the
minimum number of switching operations.
Whenever no combination is found that allows achieving the target setpoint
range, the PFC will select a combination that provides minimum deviation from
Chapter 5 PFC Setup and Operation
45
the target. When no leading (capacitive) target power factor is allowed, only
combinations that provide lagging (inductive) power factor will be checked.
The banks are connected and disconnected starting from the low-size banks,
following all pre-set switching and re-connection delays. Alternation of switching
operations is provided when needed to avoid excessive deviation from the target
power factor.
The optimization program is complete when one of the following is true:
1. The measured power factor (in PFC mode) or kvar (in RPR mode) attains the
pre-set PFC setpoint range.
2. In PFC mode, the deviation from the target power factor is less than 0.7 of
the lowest-size bank.
3. The optimal combination may not be achieved. The controlled power factor
or kvar is brought to the value that is as close as possible to the target.
Manual Mode
This mode can be used for manual adjustment of the power factor or kvar and for
testing purposes. In manual operation mode, power factor or kvar correction is
triggered by user commands entered from the front panel (see Section 4.14, PFC
Manual Mode Menu) or through communications. Each command switches in or
switches out a single capacitor bank. When there are no banks that can be
operated or an alarm condition is present, the user command is discarded.
The banks are switched in and switched out progressively, always starting from
the lowest-size bank available, following the pre-set switching and re-connection
delays.
Manual Mode is a safe, fully protected operation mode provided that the setpoint protection
overrides especially dedicated to the PFC are also operational here. Whenever the
capacitor banks are protected through the alarm setpoints and an alarm override condition
is present, the manual command will be overridden resulting in immediate or soft switch-off
of the capacitor banks.
Changing the Operation Mode
From the PFC setup menu (see Section 4.13, PFC Setup), set the operation mode
parameter to the desired mode. This entry is always enabled unless the PFC is in Shut
Down mode.
Changing from one operation mode to another mode can be done while the PFC
is running, with no need to shut it down. The new program will start immediately
from the present point achieved. No extra cycling will be made if the previous
automatic program was completed. Changing to Manual Mode will stop all
switching operations.
After changing to an automatic mode, the disconnected capacitor banks will be
put into operation after the full discharge time.
The PFC setup options (as well as certain basic configuration options) may not be changed
while the PFC is running.
46
Chapter 5 PFC Setup and Operation
Shutting the PFC Down
From the PFC setup menu, set the PFC operation mode to OFF. This will put the PFC into
Shut Down mode.
Shut Down mode provides step-by-step disconnection of all the capacitor banks
that are under the PFC control. The banks switch out progressively, following
disconnection intervals (switch-off delays). After all the banks are switched out,
the PFC is put into OFF state.
5.2.2 PFC Setpoints
The PFC can operate in Power Factor Controller (PFC) mode or Reactive Power
Regulator (RPR) mode depending on the target setpoint parameter set for the
PFC.
The PFC can provide power factor or reactive power regulation using one of four
measured values as a target setpoint:
- true power factor;
- fundamental’s power factor (displacement) ;
- true reactive power;
- fundamental’s reactive power.
When automatic operation is enabled, PFC operations are triggered automatically
by the PFC setpoint whenever the measured value is outside the user-defined
setpoint range.
PFC Setpoint Trigger
In order to operate reliably under various harmonic conditions, the PFC allows
you to choose one of the following two calculation methods for the power factor or
kvar trigger:
1. True power factor or true kvar based on the true RMS calculations. It
accounts for harmonics through the 15th, and is recommended for electrical
networks where voltage THD is no more than 5%. For higher levels of
harmonics, the power factor and kvar readings will vary too frequently, which
may result in excess cycling of the capacitors unless you drastically increase
the setpoint operate delay.
2. The power factor displacement or fundamental’s kvar based on the
fundamental harmonic measurements. It does not account for presence of
high harmonics and will give stable results in all conditions regardless of the
present harmonics level.
Operational Setpoints
Two target setpoint ranges can be defined, generally, for day and night operation,
which are switched externally through the instrument digital input. They are
designated as setpoints SP1 and SP2.
Unless you do intend to switch the setpoint ranges, specify the operational
setpoints as SP1. In this event, only the setpoint SP1 will be operational, and the
Chapter 5 PFC Setup and Operation
47
PFC will not take into account the status of the digital input. The second setpoint
will not even appear in the PFC setup menu.
If you want to use different target setpoints and switch them depending on the
time schedule or another external condition, specify the operational setpoints as
SP1-2. In this event, both SP1 and SP2 setpoint ranges will be available for
setup, and should be defined for proper operation. The PFC will always consider
the status of the digital input in order to select an appropriate setpoint range:
open = SP1, closed = SP2. Before running the PFC, configure the digital input as
a status input (see Section 4.3).
Power Factor Setpoint Ranges
The setpoint range limits are designated as L.PF1 (low target power factor) and
Hi.PF1 (high target power factor) for the first setpoint, and as L.PF2 and H.PF2
for the second setpoint.
The allowable range for either power factor setpoint is 0.5 (inductive) to -0.5
(capacitive). The default setpoint range is 0.80 to 0.98.
The target power factor limits are always specified for the I (first) and IV (fourth)
quadrants with positive (imported) active power, regardless of the location of the
instrument on the source or load side. The PFC will automatically account for the
direction of power flow providing full four-quadrant operation.
If both target power factor limits are specified for the same quadrant, the high
power factor limit should never be less than the low limit. If the target limits are
being set for two quadrants, the lagging (inductive) power factor should be
specified as the low limit and the leading (capacitive) one as the high target limit.
Whenever these relations are not fulfilled, the instrument will automatically adjust
the high target power factor to the low target limit.
Reactive Power Setpoint Ranges
The setpoint range limits are designated as L.rE1 (low target reactive power) and
Hi.rE1 (high target reactive power) for the first setpoint, and as L.rE2 and H.rE2
for the second setpoint.
The allowable range for either reactive power setpoint is -10,000 (capacitive) to
10,000 (inductive).
The target reactive power limits are always specified for the I (first) and IV (fourth)
quadrants with positive (imported) active power, regardless of the location of the
instrument on the source or load side.
The high reactive power limit should never be less than the low limit. Whenever
this is not fulfilled, the instrument will automatically adjust the high target reactive
power to the low target limit.
PFC Setpoint Operate Delay
The PFC setpoints will not respond to the poor power factor or kvar if the time
that the measured value is outside the setpoint range is less than the user48
Chapter 5 PFC Setup and Operation
defined setpoint operate delay. This makes the trigger less sensitive to fast
changes in load thus avoiding excess switching.
The operate delay timer is reloaded each time the measured power factor
oversteps the setpoint range limits.
The allowable range for the operate delay is 1 to 3600 sec. The default value is 3
sec.
Low Lacking Reactive Power
To avoid excess cycling, the power factor setpoint will not trigger the PFC if the
lacking reactive power is less than 0.7 of the lowest-size bank (usually with no
load or in presence of very low load).
5.2.3 Switching Block Delays
All bank-switching operations are performed following safety block delays in order
to avoid excess transient voltages and currents, and to prevent possible damage
to the contactors and capacitors.
Switch-on Delay (Connection Interval)
This is the amount of time after the capacitor bank switches in during which the
following switching operations are prohibited.
The PFC will not perform either connection or disconnection of the banks until the
switch-on delay timer expires. This avoids multiple switching of the capacitor
banks that would otherwise cause excess current pulses.
The switch-on delay can be adjusted from 3 to 3600 sec. The default setting is
600 sec.
Switch-off Delay (Disconnection Interval)
This is the amount of time after the capacitor bank switches out during which the
following switching operations are prohibited.
The PFC will not perform either connection or disconnection of the banks until the
switch-off delay timer expires. This avoids multiple switching of the capacitor
banks that would otherwise cause excess transient voltages and currents in the
circuits.
The switch-off delay can be adjusted from 3 to 3600 sec. The default setting is
600 sec.
Re-connection (Re-close) Delay
This is the amount of time after the capacitor bank switches out during which the
re-connection of the bank is prohibited, in order to allow the capacitors to
discharge. This avoids bringing the still-charged capacitors back after the voltage
is restored that would otherwise cause permanent damage to the contactors and
the capacitors because of extremely high over-voltage.
Chapter 5 PFC Setup and Operation
49
Normally, the capacitors discharge through fixed resistors that are connected to
the capacitors directly or via auxiliary contacts of the contactors. Refer to the
capacitor data sheet for the recommended discharge time for your capacitors.
The re-connection delay can be adjusted in the range of 3 to 3600 sec. The
default setting is 300 sec.
5.2.4 Arranging the Capacitor Banks
Sizing of the Capacitor Banks
In order to provide reliable operation of the PFC, the sequence of the capacitor
banks should admit different power combinations that must match the reactive
load of your power network. The total power of all capacitor banks should be
sufficient to provide refine power factor correction in worst cases of excessive
inductive load.
It is recommended to use one of the following sequences of the capacitor banks,
where all bank powers are multiples of the power of the first bank:
c, c, c,....c;
c, 2c, 2c,....2c;
c, 2c, 4c,....4c;
etc.
where:
c =
2c =
4c =
etc.
the power of the first capacitor bank, kvar;
twice the power of the first capacitor bank, kvar;
four times the power of the first capacitor bank, kvar;
From the PFC setup menu (see Section 4.13, PFC Setup), specify the power ratings for the
capacitor banks in kvar, progressively, starting from the first sized bank. The capacitor
banks have the same numbers as the output relays to which they must be connected.
The power ratings are not allowed to follow in descending order. Each bank must
have the same or greater size against the previous bank. When entering the bank
power, the starting size is prompted at the power of the previous bank and will not
be allowed to drop below this value.
The sized capacitor banks are not required to occupy adjacent output relays.
They may alternate with permanently switched banks and not connected banks
(see Section 5.1). In all cases, the first bank sized in kvar will be taken as the
reference bank for PFC operations, and all sized banks will be treated in one
sequence.
Adjusting the Bank Rated Power to the Operating Voltage
The PFC calculates the network response to switching operations using the bank
rated powers, normally given for the nominal (rated) voltage. Since the power of
the capacitor banks extremely depends on the operating voltage, the PFC needs
to adjust bank rated powers to the true operating voltage in the circuits.
50
Chapter 5 PFC Setup and Operation
The C192PF8-RPR allows you to choose between manual and automatic
adjustment of the capacitor bank powers. If you choose to make this manually,
specify the bank nominal voltage in the PFC setup as zero, and then enter the
reactive powers for each bank being recalculated for the operating voltage of the
banks, as follows:
Q = Qr
V2
Vn2
where:
Q
Qr
V
Vn
-
reactive power of the bank, kvar
rated reactive power of the bank, kvar
operating voltage, V
nominal (rated) voltage of the bank, V
If you allow for automatic adjustment of the bank powers, specify in the PFC
setup the nominal voltage of your capacitor banks and the individual rated power
for each capacitor bank. PFC will automatically account for the measured
operating voltage to adjust the capacitor bank powers.
5.2.5 Relay Operation (Switching Cycle) Counters
In all modes of operation, the PFC tries to equate cycling for the banks with the
same size. Whenever a number of the banks with the equal power are available,
the PFC will use the bank that has the minimum number of switching cycles.
In order to control cycling of the capacitor banks and the contactors used for
capacitor switching, the PFC maintains the individual operation counter (switching
cycle counter), for each output relay. The cycle counter contains the number of
complete switching cycles of the bank. The PFC updates the counter when it
switches in the corresponding bank.
The present status of the cycle counters can be inspected through the Status
Information Menu (see Chapter 7) or via communications. Each counter can be
cleared individually or all counters together by a single operation (see Section
4.11 and Chapter 7).
Chapter 5 PFC Setup and Operation
51
5.3 Capacitor Banks Protection
5.3.1 PFC Protective Actions
The reason for the PFC protection mechanism is to protect the capacitor banks
and contactors against harmful conditions that would lead to extremely high overvoltage, or would cause undesirable effects such as high transient voltages and
currents and high harmonics. The effect of the PFC protection is automatic
disconnection of the capacitor banks that should occur immediately in the event
of danger to capacitors, or progressively, in less dangerous situations, until alarm
conditions disappear (with minimal cycling whenever possible).
In the C192PF8-RPR, all protective functions are provided through the universal
mechanism of programmable alarm setpoints (see Section 4.6, Alarm/Event
Setpoints Menu).
The PFC itself has no embedded protection functions that may automatically disconnect
the capacitor banks in such situations. With no setpoint protection, the capacitor banks will
remain unprotected against damaging conditions unless external protection is used.
Any number of the 16 programmable setpoints can be used for PFC protection.
Section 5.3.2 provides instructions on how to program certain highly
recommended setpoints for typical alarm conditions. Notice that the effect of the
setpoints does not depend on their order in the setpoint list.
Protection of the capacitors against short circuits should be carried out separately using
either fuses or switches with over-current protection.
The three following setpoint actions are specially intended for the use with the
PFC alarm protection setpoints.
Hard Switch-Off
When alarm override condition is detected, the Hard Switch-Off action
immediately switches out all the capacitor banks including those defined as
permanently switched in. When used with the No-Volt trigger condition (see Table
4-7), this action provides the fastest possible response to voltage interruptions.
Soft Switch-Off
The Soft Switch-Off action switches off the capacitor banks progressively in preset disconnection intervals, while the alarm condition is present. This allows
circumventing over-voltage or high harmonics conditions with minimum cycling of
the capacitor banks. The banks that are defined as permanently switched in are
not affected. After the alarm condition, the PFC will return to automatic operation
after the safety delay which is 50 times the power factor setpoint operate delay.
Stop (Freeze) PFC
This action freezes automatic operation of the PFC until the alarm condition
disappears. No switching operations on the capacitor banks will be performed.
This action does not affect operations in manual mode.
52
Chapter 5 PFC Setup and Operation
5.3.2
PFC Protection Setpoints
Protection against Voltage Interruptions
The fast disconnection of the capacitor banks is required in the event of shortterm voltage interruptions that would cause damage to the still-charged
capacitors when the voltage is restored.
The No-Volt alarm override condition (see Table 4.6) along with the Hard SwitchOff action can de-energize the output relays in approximately 25 ms whenever
voltage interruption is detected.
From the Event/Alarm Setpoints Menu, set the setpoint parameters as follows:

3.0 sec
Hrd.OF
The setpoint release delay defines the amount of time before the PFC returns to
normal operation after the alarm. Set it to a non-zero value (3.0 sec in the above
example).
Over-voltage Protection
Over-voltage override condition prevents damage to capacitors at high voltage
increases that would be caused by faulty connections of the capacitors or by
voltage resonance at a higher frequency.
The high voltage override condition along with the Soft Switch-Off action is
recommended for over-voltage protection. The setpoint can respond to high
measured voltage over 120% of the operating voltage with response time of 0.3
to 300 sec. The setpoint is released without a delay when the voltage returns to a
level of 105-110% of the operating voltage. To avoid non-necessary
disconnecting of the banks, the setpoint is released immediately when the alarm
condition disappears.
From the Event/Alarm Setpoints Menu, set the setpoint parameters as follows (example):

After the alarm, the PFC will not return to automatic operation for a period of time that is
50 times the power factor setpoint operate delay.
Chapter 5 PFC Setup and Operation
53
Protection against High Harmonics
High THD protection prevents damage to capacitors at high levels of voltage
harmonics, which can be caused by voltage resonance at a higher frequency.
The effect of the high THD setpoint protection is limited progressive disconnection
of the capacitor banks until resonance conditions disappear, and then, after a
long safety delay, returning the PFC into normal operation.
The setpoint can operate at high THD of 3 to 300% depending on the network
conditions with a delay of 0.3 to 300 seconds. The setpoint is released when the
voltage THD drops to a level of 10-20% of the setpoint operate limit. To avoid unnecessary disconnecting of the banks, the setpoint is released without a delay.
From the Event/Alarm Setpoints Menu, set the setpoint parameters as follows (example):

After the alarm, the PFC will not return to automatic operation for a period of time that is

Protection by External Triggers
A protection setpoint can also be used to disconnect the capacitor banks in
response to an external contact status provided through the instrument status
input. This may be useful in substations with generators or large synchronous
motors that generate a large amount of reactive power. The contact should be
closed if generators or motors are working and opened if they are not working.
The control signal can be provided from normally open auxiliary contacts of the
start-up contactors.

Chapter 6 Data Display
When using direct wiring (PT Ratio = 1), voltages are displayed in 0.1 V units, currents
in 0.01 A units, and powers in 0.001 kW/kvar/kVA units. For wiring via PTs (PT Ratio >
1), voltages are displayed in 1V units, currents in 0.01 A units, and powers in 0.001
MW/Mvar/MVA units. When the value width is over the window resolution, the right
most digits are truncated
By default, the maximum range for energy readings is 99,999,999 MWh/Mvarh/MVAh.
Beyond this value, the reading will roll over to zero. When the energy reading exceeds
the window resolution, the right-most digits are truncated. To avoid truncation, you can
change the energy roll value to lower limit via the User Selectable Options menu (see
Section 4.9). Negative (exported) energy readings are displayed without a sign.
Per phase power and power factor readings are displayed only in 4LN3/4LL3 and
3LN3/3LL3 wiring modes (see Section 4.1) if the phase powers display is enabled in
the Display Setup menu (see Section 4.8).
Phase energy readings are displayed only in 4LN3/4LL3 and 3LN3/3LL3 wiring modes if
they are enabled in the User Selectable Options menu (see Section 4.9).
When the 4LN3 or 3LN3 wiring mode is selected, the voltages will be line-to-neutral; for
any other wiring mode, they will be line-to-line voltages.
Displayed only in the 4LN3 or 3LN3 wiring mode.
6.3 Device Diagnostics Display
When the device restarts, either after power up, or as a result of the device
diagnostics test, the C192PF8-RPR display shows for one second the diagnostics
code. Diagnostics codes are listed in Table 5-2. Code ‘8’ indicates normal power
up.

External reset (warm restart)
The C192PF8-RPR performs full diagnostics tests after restart and periodically
during operation. The diagnostics results are written to the appropriate bits of the
device self-check diagnostics register accessible through communications (see
the communications reference guides shipped with your instrument). When a
non-critical error is detected, the C192PF8-RPR sets a corresponding fault bit in
the diagnostics register and restart operations showing the last recorded
diagnostics code on the display. Frequent failures may be the result of excessive
electrical noise in the region of the instrument. If the instrument continuously
resets itself, contact your local distributor.
Chapter 6 Data Display
61
When the device detects a corrupted configuration setup or incompatible setup
setting, it sets a corresponding fault bit in the diagnostics register, resets the
corrupted setup to default and rises a critical (unrecoverable) error. Diagnostics
status can be viewed through the Status Information Menu (see Section 7.2), and
tested through a setpoint via the Device Fault trigger. The device fault is cleared
when the setup is rewritten, or device diagnostics is cleared either through the
Status Information Menu (see Section 7.1), or through communications.
