Kompally), Secunderabad – 500100, Telangana State, India To introduce all kinds of circuit. Protective relays and devices have been developed over 100 years ago to provide "last line" of defense for the electrical systems. They are intended to quickly identify a fault and isolate it so the balance of the system continue to run under normal conditions. Long term cost reduction (TCO) for trainings and maintenance by reduce variety of relays A fast and selective arc fault mitigation for air-insulated LV & MV switchgear and Relion protection and control relays and sensor technology protect staff and plant facilities for many years. Differential Relay: Compares currents at two points; operates when there is a difference (used in transformers and generators).
Any electric power system consists of three principal parts: power generation, power transmission, and power distribution. In order to make protection designs adequate, power systems are divided into
