AEE is experienced with setting each of the following generic categories of relaying schemes and any of their many variants. Where applicable, ANSI relay function codes are provided in brackets ():

  • Overcurrent (50, 51, 51VC, 51VR, 67),
  • Circuit breaker fail (50BF)
  • Earth Fault (50N, 50G, 51N, 51G, 67N, 67G, 64R),
  • Negative Phase Sequence Overcurrent (46),
  • Transformer differential (87T),
  • Busbar differential (87B),
  • Line and cable differential (87L/87C),
  • Rotating machine differential (87G/87M),
  • Induction motor protection,
  • Capacitor bank protection,
  • Distance (21),
  • Pole slipping/Out-of-Step (78),
  • Rate of Change of Frequency [ROCOF],
  • Vector Shift,
  • Under & Over Frequency (81U & 81O),
  • Under & Over Voltage (27 & 59),
  • Neutral Voltage Displacement, (59N),
  • Check Synchronising (25),
  • Directional Power (32),
  • Loss of Field/Under Excitation (40),
  • Auto Reclosing (79).

AEE provides settings not only for relays, but for all makes of reclosers, residual current devices, air circuit breakers and moulded case circuit breakers. We also design fused protection systems in applications where simple robust protection schemes are preferred.

In short, no matter what protects your power system, AEE can set it.
