To accomplish the design objectives, four criteria for protection should be considered: fault clearing time; selectivity; sensitivity and reliability (dependability and security). While this is bad, It's not a. The objective of relay protection is to quickly isolate a faulty section from both ends so that the rest of the system can function satisfactorily. The functional requirements of the relay: The most important requisite of the protective relay is reliability since they supervise the circuit for a. Protective relays and devices have been developed over 100 years ago to provide “lastline”of defense for the electrical systems. Selectivity: It is the ability of the protective system to select correctly that part of the system in trouble and disconnect the faulty part without disturbing the rest of. This document supplements PJM Manual 07 which contains the minimum design standards and requirements for the protection systems associated with the bulk power facilities within PJM.
