SE-701 Series - Ground-Fault Monitor

Roll Over to Zoom
Operates on AC solidly grounded and AC resistance grounded systems.
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.



Adjustable pickup

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

Output contacts

Form A and Form B ground-fault output contacts for operation of separate annunciation and trip circuits

Analog output
(0 - 5 V)

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

CT-Loop monitoring

Alarms when CT is not connected

Selectable DFT or peak detection filtering

Compatible with variable-speed drives

Harmonic filtering

Eliminates nuisance tripping

Non-volatile trip memory

Retains trip state while de-energized to simplify troubleshooting

Microprocessor based

No calibration required, saves on maintenance cost

Universal power supply

Allows operation in application where one side of PT is faulted, provides flexibility for numerous applications
