Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty Of Engineering - Department Of Electrical Power and Machines Summary: Due to the inductive nature of power systems a decaying DC component appears in the fault current waveform , while the settings of the relay is based on pure steady state calculations.This decaying DC component might affect the operation of the protective relays and make theprotection system loose its security due to mal - trips
