Abstract :
Setting instantaneous overcurrent (IOC) relays on subtransmission lines has not been considered a complicated procedure by most utilities. However, undesirable operations have drawn attention to their intended function and application. This report addresses the causes for erroneous instantaneous overcurrent relay settings to help protection personnel avoid future undesirable operations
