Description The T2100 Excitation Loss Relay protects against loss of excitation in a synchronous generator. T2100 detects the high-inductive current running into a generator in case of low excitation. The faulty generator breaker is tripped, thus protecting the generator, and avoiding undervoltage on the busbar with a possible blackout of the system. The T2100 calculates I x sin φ, representing the reactive power. If the reactive power becomes negative and exceeds the preset level (0.5-1.5 x IN), the pickup LED will indicate and the delay timer will be started. After the preset time (2-20 sec.) has expired, the output relay and LED will be activated, provided that the negative reactive power level was exceeded for the entire delay time
