Differential Relay: Compares currents at two points; operates when there is a difference (used in transformers and generators). Protective relays and devices have been developed over 100 years ago to provide "lastline"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. Abstract: Information on the concepts of protection of ac transmission lines is presented in this guide.
