Abstract :
INDUCTION type relays will of course operate at their intended current values and time settings only when the shape of the current wave applied during a fault is similar to that of the test wave. The shape of the current wave in the relay during fault is dependent upon the wave form of the fault currents and voltages, and the characteristics of current transformers and secondary circuits.
