Functions:

  • Monitors up to three portable power cables
  • Detects ground faults in each cable or connected equipment
  • Detects open ground-check loop, and shorted ground-check loop in each cable

Features:
  • Zener-characteristic termination assembly provides reliable ground-check-loop verification
  • Loop-resistance calibration not required
  • LED indication of Ground-Check Trip, Valid, Open, and Short for each cable
  • LED indication of Ground-Fault Trip and Sensor Health for each cable
  • LED indication of Power and Diagnostic Error
  • Exceeds requirements of CSA Standard M421-00 Use of Electricity in Mines with fail-safe ground-fault and ground-check circuits
  • Universal power supply accepts a wide range of ac and dc voltages
  • Optional 24/48 Vdc power supply
  • DFT (harmonic) filter prevents false ground-fault operation
  • Low open-circuit ground-check voltage is not a hazard to personnel
  • Wide range of ground-fault current and time set points
  • Conformally coated circuit boards
  • Uses the same termination assembly as the SE-135
  • Optional IEEE 802.3 (Ethernet) with Modbus TCP protocol
  • Free SE-MON145 PC-interface software
  • Five year warranty

Manual:
  • SE-145 Manual (Preliminary)

Typical Applications:
  • Mining, shore-to-ship power, pumps, and cranes
  • Used on systems up to 25 kV
  • For applications where protection is required only for a single cable, see the SE-134C

System Components: The SE-145 requires an SE-TA12A-series termination device for each cable. An SE-CS10-series current sensor for each cable is required for ground-fault protection.
IEEE Device Numbers: 3GC, 50G, 50N, 51G, 51N
