Operates on AC solidly grounded and AC resistance grounded systems. The SE-704 is a microprocessor-based ground-fault relay for resistance- and solidly-grounded systems. It offers very sensitive ground-fault detection as low as 10 mA and can be used on systems with significant harmonic content.The SE-704 provides feeder-level protection or individual-load protection. 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
  • Adjustable pickup (10 mA to 5 A) - adjustable trip setting provides a wide range of low level protection and system coordination
  • Adjustable time delay (30 ms to 2 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
  • Analog output (0 to 5 VDC and 0 to 1 mA) allows for connecting an optional meter (PGA-0500) or control system
  • CT-loop monitoring - alarms when CT is not connected
  • Selectable fail safe or non-fail safe operating modes allows connection to shunt or undervoltage breaker coil
  • Harmonic filtering eliminates nuisance tripping
  • Non-volatile trip memory retains trip state when de-energized to simplify troubleshooting
  • 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
