PGR-6100 Ground-Fault & Insulation Monitor
1. GENERAL
The PGR-6100 Ground-Fault & Insulation Monitor can
detect a motor ground fault whether the motor is running
(Online mode) or stopped (Offline mode), and can be
used to protect a motor supplied by a solidly grounded,
resistance-grounded, or ungrounded system. On an
ungrounded system, use only the Offline mode.
On grounded systems, a current transformer (CT) is
used to detect ground-fault current as low as 10 mA when
the motor is running. Insulation resistance is measured to
detect a fault when the motor is stopped. Online or
Offline mode is selected with a digital input connected to
a starter auxiliary contact.
In the Online mode, ground-fault current is sensed by a
PGC-5000-series zero-sequence CT. The trip level of the
ground-fault circuit is selectable from 10 mA to 3 A. Trip
time is selectable from <50 ms to 10 s. Additional
current-detection features include harmonic filtering, a
relay output that can operate in the fail-safe or non-failsafe mode, CT-connection detection, LED trip, LED
power, and LED open-CT indication, autoreset or
latching trips with front-panel and remote reset, a test
button, and a 0- to 1-mA-analog output.
In the Offline mode, insulation-resistance monitoring is
enabled with a selectable 250-k to 2-M alarm-setting
range. Additional insulation-monitoring features include
a relay output that can operate in the fail-safe or non-failsafe mode, LED active and low-resistance indication, and
a 0- to 1-mA-analog output.
The PGR-6100 can be directly connected to a supply
up to 1.3 kV. For systems from 1.3 to 5 kV, use a PGH5000 High Tension Coupler. For systems from 5 kV to
6 kV, use a PGH-6000 High Tension Coupler.
2. OPERATION
2.1 OUTPUT RELAY OPERATING MODE
In the fail-safe mode the output relays energize when
power is applied and the ground-fault and insulationresistance circuits are not tripped. Fail-safe mode is the
factory setting.
For non-fail-safe operation connect terminals 19-20
and 22-23. The respective output relay will energize
when a fault occurs. See Fig. 2.
2.2 PGR-6100 OPERATING MODE
Connect terminals 27 and 28 to a normally closed
(Form B) auxiliary starter contact. When terminals 27
and 28 are open, Online mode is selected (insulation
monitoring off). When terminals 27 and 28 are connected,
Offline mode is selected (insulation monitoring active).
Page 1
Rev. 2-B-111014
2.2.1 ONLINE OPERATION
In Online mode, the PGR-6100 in conjunction with a
PGC-5000-series zero-sequence current sensor operates
as a ground-fault relay.
2.2.2 OFFLINE OPERATION
The PGR-6100 changes mode by means of an auxiliary
contact on the main contactor when the motor is off. It
becomes an insulation-resistance monitor and imposes a
small dc voltage to the motor windings and supply cable
from the motor starter. Leakage to ground is detected.
2.3 FRONT-PANEL CONTROLS
2.3.1 GROUND-FAULT TRIP LEVEL
The Leakage Current I selector switch is used to set the
ground-fault trip level from 10 mA to 3 A. For groundfault detection, the switch setting must be set substantially
below the prospective ground-fault current. To avoid
sympathetic tripping, the switch setting must be above the
charging current of the protected feeder.
2.3.2 GROUND-FAULT TRIP TIME
The PGR-6100 has a definite-time trip characteristic.
In tripping systems, the TIME DELAY selector is used to
set the ground-fault trip time for coordination with
upstream and downstream ground-fault devices. Trip time
is selectable from < 50 ms to 1.0 s. Coordination requires
the same trip level for all ground-fault devices in a system
and the trip time to progressively increase upstream. The
amount of equipment removed from the system will be a
minimum if the first ground-fault device to operate is the
one immediately upstream from the fault.
2.3.3 INSULATION RESISTANCE RESPONSE
The PGR-6100 insulation resistance function has an
adjustable alarm range of 250 k to 2 M. There is no
selectable time delay. The unit will operate in less than
three seconds.
2.3.4 RESET
The front-panel RESET button is used to reset latching
trips. After a fault has been cleared, cycling the supply
voltage will also reset the PGR-6100.
To use the PGR-6100 in autoreset mode, connect
terminals 18-19 and 21-22. See Fig. 2.
The reset function is not instantaneous. Press the RESET
button for several seconds.

Page 2
Rev. 2-B-111014
2.3.5 TEST
The TEST button will test both leakage-current and
insulation-resistance circuits regardless of the selected
operating mode. Press the TEST button for at least eight
seconds to complete test. All LED’s will light and relay
contacts will change to fault/alarm state. In the default mode
(latching), the tripped state will remain until reset. Allow
eight seconds before operating the RESET button.
2.7 REMOTE RESET
For remote reset, connect a switch or button with a
normally closed contact between the neutral side of the
supply voltage and terminal 5. See Fig. 2.
For an alternate configuration, connect a normally open,
double-pole, single-throw switch across terminals 18 and 19,
and terminals 21 and 22. A momentary connection across
these terminals will reset the PGR-6100.
2.4 FRONT-PANEL INDICATION
2.4.1 POWER
The green LED labelled PWR indicates presence of
supply voltage.
2.8 CT VERIFICATION
A ground-fault trip will occur and the red CT LED will
light when a PGC-5000-series CT is not connected to
terminals 16 and 17.
2.4.2 >I
The red LED labelled >I indicates a ground-fault trip.
3. INSTALLATION
2.4.3 CT
The red LED labelled CT indicates that a PGC-5000series current sensor is not connected. See Section 2.8.
2.4.4 ACTIVE
The green LED labelled ACTIVE indicates that the
Offline monitoring function is active. The insulation
monitoring or lockout function is active when terminals 27
and 28 are connected. See Section 2.2.
2.4.5 <R
The red LED labelled <R indicates a low resistance.
2.5 ANALOG OUTPUTS
2.5.1 OUT I
A non-isolated, 0- to 1-mA output (terminals 24 and 25)
indicates ground-fault current sensed by the CT. The fullscale value corresponds to the ground-fault trip setting. For
example, if the ground-fault trip setting is 30 mA, then 1 mA
output will be indicated when the measured current is 30
mA. The output is linear between zero and full scale. See
Figs. 2 and 6.
2.5.2 OUT R
A non-isolated, 0- to 1-mA output (terminals 25 and 26)
indicates insulation resistance. The metering output relates
to an insulation-resistance range of 0 to infinity. See Figs. 2
and 7.
2.6 REMOTE TEST
Use external switches to test the current-sensor detection,
insulation-monitoring
activation,
and
insulationmonitoring functions. See Fig. 2. Response to a test
input can take several seconds.
NOTE: Mounting, terminal block connections and wiring
must conform to applicable local electrical codes. Check
all applicable codes prior to installation.
This ground-fault monitoring system consists of a
PGR-6100-series Ground-Fault & Insulation Monitor, a
PGC-5000-series CT, and for systems over 1.3 kV, a
PGH-5000 or PGH-6000 High Tension Coupler
connected as shown in Fig. 2.
A PGR-6100 can be surface or DIN-rail mounted. See
Fig. 1.
Use terminal 6 (L1) as the line terminal for a 120 or
240 Vac supply. Use terminal 7 as the line terminal for a
24 Vac supply. Use terminal 5 (L2/N) as the neutral
terminal. Connect terminal 30 to ground.
Pass the phase conductors through the CT window and
position them in the centre of the opening (for four-wire
and single-phase systems, also pass the neutral conductor
through the CT window). Do not pass ground conductors
through the CT window. In applications that require
shields or drain wires to pass through the CT window,
return them through the CT window before connecting
them to ground. CT connections are not polarity
sensitive. Applications in electrically noisy environments
require twisted- or shielded-twisted-pair CT-secondary
conductors. Connect the CT-secondary leads to terminals
16 and 17, and connect the shield to terminal 17. See
Fig. 3 for PGC-5000-series CT dimensional drawings.
If insulation monitoring is required, connect terminals
27 and 28 to a normally closed contact on the motor
starter.
For systems up to 1.3 kV, connect terminal 2 to one
phase of the load side of the starter.
Connect an optional PGA-0500 Analog Current Meter
and PGA-0510 Analog Ohm Meter as shown in Fig. 2.
Meter outline, dimensions, and cutout size are shown in
Figs. 6 and 7.

6. TESTS
6.1 GROUND-FAULT TEST
Some jurisdictions require periodic ground-fault
performance tests. A test record form is provided for
recording the date and the result of the performance
tests. The following ground-fault system tests are to be
conducted by qualified personnel.
a) Evaluate the interconnected system in accordance
with the overall equipment manufacturer’s detailed
instructions.
b) Verify proper location of the PGC-5000-series CT.
Ensure the cables pass through the CT window. This
check can be done visually with knowledge of the
circuit.
The connection of the current-sensor
secondary to the PGR-6100 is not polarity sensitive.
c) Verify that the system is correctly grounded and that
alternate ground paths do not exist that bypass the
current sensor. High-voltage testers and resistance
bridges can be used to determine the existence of
alternate ground paths.
d) Verify proper reaction of the circuit-interrupting
device in response to a simulated or controlled
ground-fault current.
To simulate ground-fault
current, use CT-primary current injection. Fig. 8
shows a test circuit using the SE-400 Ground-FaultRelay Test Unit. The SE-400 has a programmable
output of 0.5 to 9.9 A for a duration of 0.1 to 9.9
seconds. Fig. 8 shows the use of resistors that reduce
the injected current to 10% of the SE-400 setting. Set
the test current to 120% of the PGR-6100 setting.
Inject the test current through the CT window for at
least 2.5 seconds. Verify that the circuit under test
has reacted properly. Correct any problems and retest until the proper reaction is verified.

e) Record the date and the results of the test on the
attached test-record form.
NOTE: Do not inject test current directly into CT-input
terminals 16 and 17.

6.2 INSULATION TEST
Perform this test with the starter open and appropriate
lock-out procedures.
Connect a 10-k resistor between one phase and
ground at the line side of the starter or motor terminal
box. Select a phase that is not connected to PGR-6100
terminal 2 (or the PGH-5000 or PGH-6000). The
PGR-6100, operating in Offline mode as indicated by the
green ACTIVE LED, will alarm, operating the K1 low
insulation output relay and lighting the red <R LED.
