Are high sensitivity requirements for relay protection
To accomplish the design objectives, four criteria for protection should be considered: fault clearing time; selectivity; sensitivity and reliability (dependability and security). The sensitivity should be sufficient to ensure reliable protec-tion during s c at the end of its specified zone under. Selectivity is a mandatory requirement for all protection, but the importance of it depends on the application. While this is bad, It's not a. 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. The paper considers the use of various communications channels, including direct relay-to-relay fib r-optic channels and multiplexed digital fiber-optic networks.
