AQ200-Transformer-Protection-Relay-T216-500×375

Arc Protection System

The AQ T216 transformer protection relay provides for both low and high side overcurrent, earth-fault, negative sequence and two independent restricted earth-fault instances.

The AQ T216 can be applied for generator and motor differential protection as well. The AQ T216 communicates using various protocols including IEC 61850 substation communication standard.

  • 2 winding transformer differential (87T)
  • High/low impedance restricted earth fault / cable end differential * (87N1, 87N2)
  • Transformer thermal overload (49T/49RTD)
  • Three-phase overcurrent, 2+2 stages INST, DT or IDMT (50/51)
  • Earth-fault (sensitive), 3 stages INST, DT or IDMT (50/51N)
  • Harmonic overcurrent / inrush blocking, 4 stages INST, DT or IDMT (50/51H, 68)
  • Current unbalance / broken conductor, 2+2 stages INST, DT or IDMT (46/46R/46L)
  • Breaker failure protection (50BF/52BF)
  • Arc protection (option) (50ARC/50NARC) (12 sensors +2xHSO +BI)
