Over Current Relay Working Principle Types | Electrical4U In an over current relay or o c relay the actuating quantity is only current. There is only one current operated element in the relay, no voltage coil etc. are required to construct this protective relay. Protective relay In electrical engineering, a protective relay is a relay device designed to trip a circuit breaker when a fault is detected.: 4 The first protective relays were electromagnetic devices, relying on coils operating on moving parts to provide detection of abnormal operating conditions such as over current, over voltage, reverse power flow, over ... Relay A relay is an electrically operated switch. Many relays use an electromagnet to mechanically operate a switch, but other operating principles are also used, such as solid state relays. Relay Terminology Altech Corp Relay Release Time: The time interval from coil de energization to the functioning time of the last contact to function. Safety Relay: An electro mechanical relay with Fundamental characteristics of a circuit breaker ... Short circuit relay trip current setting (Im) Short circuit tripping relays (instantaneous or slightly time delayed) are intended to trip the circuit breaker rapidly on the occurrence of high values of fault current.
