    Oct 22, 2020 · Based on application the protection relay can be categorized as-Primary relay. Backup relay. Primary relay or primary protection relay is the first line of power system protection whereas backup relay is operated only when primary relay fails to be operated during a fault. Hence backup relay is slower in action than primary relay. The generator paralleling controller (GPC-3) is a highly versatile and compact generator paralleling controller designed for engineers who prefer to carry out application programming in a PLC.
