Requirements for Relay Protection of Transmission Lines

Home / Requirements for Relay Protection of Transmission Lines

The International Electrotechnical Commission (IEC) is currently working on a new series of standards that covers the functional requirements of measuring relays and related equipment used to protect electrical transmission and distribution systems. Applications of the concepts to accepted transmission line-protection schemes are also presented. Many important issues, such as coordination of settings, operating times, characteristics of. Transmission lines act like the arteries in the human circulatory system, moving electrical power from were it is produced by generators to where it is consumed at load centers. For example, unselective protection operation during a medium voltage network fault will cause an outage for an unnecessarily large number of consumers.
