Description

The PGR-5701 is a microprocessor-based ground-fault relay for

resistance- and solidly grounded systems. It is uniquely suited for

use on systems with significant harmonic content. The PGR-5701

can provide main-plant protection, feeder-level protection, or

individual-load protection. Proper current transformer selection

provides the desired pickup range. The output contacts can be

connected for use in protective tripping circuits or in alarm indication

circuits. The analog output can be used with a PLC or a meter.

PGC Family Ground-Fault Current Transformer

Required current transformer, model depending on

application. We offer a variety of sensitive CTs with

5- and 30-A primaries.

PGA-0500 Analog % Current Meter

Optional panel-mounted analog meter displays

ground-fault current as a percentage of the CT

primary rating.

Ground fault (50G/N, 51G/N)

beNeFitS

Trip setting based on input CT primary, allows use

with any CT

Adjustable trip delay allows quick protection and

system coordination

Form A and Form B ground-fault output contacts for

operation of separate annunciation and trip circuits

Allows for connecting an optional (PGA-0500)

meter or a control system

Alarms when CT is not connected

Compatible with variable-speed drives

Eliminates nuisance tripping

Retains trip state when de-energized to simplify

troubleshooting

No calibration required saves on maintenance cost

Allows operation in application where one side

of PT is faulted
