Power system protection ppt

Purpose of Protection System: The protective relaying system senses the abnormal condition of power system and gives an alarm or isolates the defective system from the healthy system. A fault in an electrical system is defined as a defect in its electrical circuit due to which the current is diverted from the intended path.1/5(1). Power System Protection. Zones of Protection • For fault anyway within the zone. the protection system responsible to isolate everything within the zone from the rest of the system. • Isolation done by CB • Must isolate only the faulty equipment or section.

Zones of Protection • By dividing the power system into protection zones the extent of .CHAPTER – 1. Basic ideas of Relay Protection. A good electric power system should ensure the availability of electrical power without any interruption to. Is achieved by two main methods. – Time-grading/Current Grading. • Relays are set to operate depending on the time and current characteristics. – Unit systems. complete description of devices used in power system protection such as circuit breakers, relays, ct, pt, dc supply system and other devices.
