Generator protection

The relay type NG10 provides sensitive, high operating speed and selective differential protection against phase-to-phase and phase-to-ground short circuits of motors/generators or short lines.

  • Phase overcurrent side H and side L
  • Maximum Residual Overcurrent
  • Low impedance restricted earth fault
  • Double slope biased differential for Generator/ Motor/Transformer
  • Breaker Failure
  • CT Supervision
  • Trip Circuit Supervision
SW Pack optional configuration
  • Thermal with Pt100 Probes
