Abstract :
Part I expressed concerns about using IEEE Standard C37.110-1996 (1+X/R) criteria for sizing current transformers (CT´s) for feeder short-circuit conditions [1]. Part II introduces an overview of relay filter algorithms, and proposes responsibilities of the IEEE Power System Relay Committee (PSRC), operating company and engineering company electrical power engineers, CT manufacturers, switchgear manufacturers, and relay manufacturers to guarantee CT/relay system performance. International Electrotechnical Commission (IEC) responsibilities are also included.
