Protection Relays and Controls

Ground-Fault Protection–Grounded Systems

SE-701 SERIES (PGR-5701)

Ground-Fault Monitor

Description

The SE-701 is a microprocessor-based ground-fault relay for resistance-

and solidly-grounded systems. In addition to common systems, it is

uniquely suited for use on systems with signiﬁcant harmonic content.

The SE-701 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.

Features & Beneﬁts

FEATURES

BENEFITS

Adjustable pickup

(1-99%)

Trip setting based on input CT primary, allows use with

any CT. Minimum 50 mA with EFCT Series.

Adjustable time delay

(50 ms-2.5 s)

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

Output contacts

Analog output

(0-5V)

Allows for connecting an optional meter (PGA-0500) or a

control system

Simpliﬁed Circuit Diagram

CT-Loop monitoring

Alarms when CT is not connected

Compatible with variable-speed drives

Eliminates nuisance tripping

Selectable DFT or peak

detection ﬁltering
