1. INTRODUCTION
1.1 General
The PGR-5701 is a microprocessor-based ground-fault relay for resistance-
grounded and solidly grounded systems. It is uniquely suited for use on systems with
significant harmonic content. Its output relay can operate in the fail-safe or non-fail-
safe mode for undervoltage or shunt-trip applications. The PGR-5701 has one output
relay with isolated normally open and normally closed contacts for use in independent
control circuits. Additional features include LED trip, power, and inhibit indication,
autoreset or latching trips with front-panel and remote reset, trip memory, test switch,
self diagnostics, 0- to 5-V analog output, inputs for standard and sensitive ground-fault
current transformers, CT verification for sensitive current transformers, digital selector
switches, switch-selectable algorithms for fixed-frequency or variable-frequency
applications, and an inhibit that can be enabled to prevent the output relay from
operating during a high-current ground fault.
Ground-fault current is sensed by a core-balance zero-sequence current transformer
(CT). The trip level of the ground-fault circuit is switch selectable in 1% increments
from 1 to 99% of the CT-primary rating.
1.2 Current-Transformer Selection
A PGR-5701 has inputs for 1-, 5-A, and sensitive 50-mA-secondary CT’s. Choose a
CT that provides the required ground-fault-trip range.
For ground-fault detection, the ground-fault trip level must be substantially below the
prospective ground-fault current. In a solidly grounded system, prospective ground-
fault current is similar to phase-fault current. In a resistance-grounded system,
prospective ground-fault current is defined by the neutral-grounding-resistor let-
through-current rating.
In a solidly grounded system, protection against arcing ground faults requires a
ground-fault CT that will detect low-level fault current but not saturate up to the
operating value of the system overcurrent protection. In general, immunity to
saturation is proportional to CT mass.
To eliminate nuisance tripping, surge current must not saturate the CT.
For low-level ground-fault protection use a PGC-3026 PGC-3082, or PGC-3140,
sensitive earth-fault CT with a 5-A-primary rating. However, protection at this level
might not be possible because of high surge current or prospective ground-fault
current.

2. OPERATION
2.1 Configuration-Switch Settings
See Fig. 1.
2.1.1 Relay Operating Mode
Switch 1 is used to set the operating mode of the output relay. In the fail-safe mode,
the output relay energizes when the ground-fault circuit is not tripped. In the fail-safe
mode, non-volatile memory retains the trip status of the PGR-5701. If tripped, and the
supply voltage is cycled, the PGR-5701 will remain tripped, with the trip relay de-
energized and the TRIP LED on, until reset.
In the non-fail-safe mode, the output relay energizes when a ground-fault trip occurs.
In the non-fail-safe mode, trip status is not retained in non-volatile memory.
2.1.2 Trip Inhibit
Switch 2 is used to select Class I or Class II operation. In the OFF position, high-
current trip inhibit is off for Class I operation. In the ON position, high-current inhibit is
on for Class II operation. If high-current trip inhibit is on and ground-fault current
escalates above eleven times the CT-primary rating before the ground-fault circuit trips,
the output relay will not operate until ground-fault current falls below eight times the CT-
primary rating. This feature allows overcurrent protection to operate in applications
where the ground-fault current can be larger than the interrupting capacity of the device
tripped by the PGR-5701.
2.1.3 CT Verification
Switch 3 is used to enable CT verification with a PGC-3000-series CT. In the ON
position, a trip will occur if the CT is disconnected. Switch 3 must be in the OFF
position when a PGC-3000-series CT is not used.
2.1.4 Filter Selection
Switch 4 is used to select the filtering algorithm for a fixed-frequency (50/60 Hz) or
variable-frequency application. The FIXED FREQUENCY setting uses a DFT filter that
allows lower trip levels to be used by rejecting harmonics that can cause nuisance
tripping.
The VARIABLE FREQUENCY setting uses a peak-detection algorithm with a wider
band width for fault detection in variable-frequency drive applications.
2.1.5 Reset Mode
Switch 5 is used to select autoreset or latching trips. See Section 2.2.3.
2.2 Front-Panel Controls
2.2.1 Ground-Fault Trip Level
The % CT PRIMARY selector switches are used to set the ground-fault trip level as
a percentage of the CT-primary rating.
In tripping systems, a ground-fault trip level of 10 to 20% of the prospective ground-
fault current is often used. In alarm-only systems, a value of 50% of the prospective

ground-fault current is often used. To avoid sympathetic tripping, the trip level must be
above the charging current of the protected feeder.
A 0% selection provides protection at 1%.
2.2.2 Ground-Fault Trip Time
The PGR-5701 has a definite-time trip characteristic. The TIME (s) selector switch
is used to set the ground-fault trip delay time for coordination with upstream and
downstream ground-fault devices. 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.
2.2.3 Reset
If the Reset Mode switch is in the LATCHING position, a trip remains latched until
the RESET switch is pressed or the remote-reset terminals are momentarily
connected. In the non-fail-safe mode, cycling the supply voltage will also reset the
PGR-5701.
If the Reset Mode switch is in the AUTORESET position, a trip will reset when the
fault is removed.
The reset circuit responds only to a momentary closure so that a jammed or shorted
switch will not prevent a trip. The front-panel RESET switch is inoperative when the
remote-reset terminals (6 and 7) are connected.
2.2.4 Test
The TEST switch is used to test the ground-fault circuit, the indication, and the
output relay. When the TEST switch is pressed for one second, a test signal is applied
to the ground-fault-detection circuit, the circuit will trip, the TRIP LED will light, and the
output relay will operate. If high-current inhibit has been selected, the INHB LED will
light.
2.3 Front-Panel Indication
2.3.1 Power
The green LED labeled PWR indicates the presence of supply voltage.
2.3.2 Trip
The red LED labeled TRIP indicates a trip. A solid red LED indicates a ground-fault
trip. A regularly flashing LED indicates a trip initiated by a CT fault. Two fast flashes
indicate a diagnostic trip. See Section 2.5.
2.3.3 Trip Inhibit
The yellow LED labeled INHB indicates that output-relay operation was inhibited
during a high-current ground fault. See Section 2.1.2. When a ground-fault trip occurs
during a high-current ground fault, both the TRIP and INHB LED’s will be ON. Inhibit
indication is reset when the ground-fault trip is reset. Inhibit operation and indication
will not respond if the Trip-Inhibit switch is in the OFF position.
Rev. 6 Page 5
PGR-5701 Ground-Fault Relay
2.4 Analog Output
The non-isolated, 0- to 5-V analog output indicates ground-fault current sensed by
the ground-fault CT. The output is 5 V when ground-fault current is 100% of the CT-
primary rating.
2.5 Self Diagnostics
A diagnostic trip is indicated by two flashes of the TRIP LED. It can be caused by a
diagnostic problem detected by the watchdog timer or from an incorrect reading from
non-volatile memory. Press RESET or cycle supply voltage. If the problem persists,
contact 1-800-TEC-FUSE (1-800-832-3873).
3. INSTALLATION
A PGR-5701 can be surface or DIN-rail mounted. See Fig. 1. Panel mounting
requires a PGK-0055 or PGK-0060 Panel-Mount Adapter. See Fig. 6.
Pass the phase conductors through the CT window as shown in Fig. 2 (for 4-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. If a ground-fault CT with a 5-A secondary is
used, connect it to terminals 2 and 3 (terminals 1 and 3 with a 1-A secondary) and
ground terminal 3. If a PGC-3000-series CT is used, connect it to terminals 4 and 5,
connect the shield to terminal 5, and ground terminal 5. Remove the connection to
terminal 9 for dielectric-strength testing—all inputs and outputs have ANSI/IEEE
C37.90 surge-protection circuits that conduct above 300 Vac. See Figs. 3, 4, and 5 for
sensitive PGC-3000-series CT dimensional drawings.

6. GROUND-FAULT PERFORMANCE TEST
To meet the requirements of the National Electrical Code (NEC), as applicable, the
overall ground-fault protection system requires a performance test when first installed.
A written record of the performance test is to be retained by those in charge of the
electrical installation in order to make it available to the authority having jurisdiction. A
test-record form is provided for recording the date and the final results 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 ground-fault current transformer. Ensure the cables
pass through the ground-fault-current-transformer window. This check can be done
visually with knowledge of the circuit. The connection of the current-transformer
secondary to the PGR-5701 is not polarity sensitive.
c) Verify that the system is correctly grounded and that alternate ground paths do not
exist that bypass the current transformer. 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. 7 shows a test circuit using a PGT-0400 Ground-Fault-Relay
Test Unit. The PGT-0400 has a programmable output of 0.5 to 9.9 A for a duration
of 0.1 to 9.9 seconds. Set the test current to 120% of the PGR-5701 setting. Inject
the test current through the current-transformer window for at least 2.5 seconds.
Verify that the circuit under test has reacted properly. Correct any problems and re-
test 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 1, 2, 3, 4, and 5.
