Applications and Characteristics Of Overcurrent Relays (ANSI 50, 51…
网页2022年6月3日 · On electromechanical relays, the 50 function can be added as an instantaneous attachment to a 51 time-overcurrent relay. If a relay has both 50 and 51 functions present and enabled is referred to as a 50/51 relay.
Instantaneous and Time-overcurrent (50/51) Protection
网页Instantaneous overcurrent, ANSI/IEEE code 50, is used most often in resistive systems where current spikes are undesirable and should cause the circuit branch to open. Time overcurrent, ANSI/IEEE code 51, is employed in inductive systems where current is expected to rise for a short duration after voltage changes before returning to a normal level.
What is the difference between 50/51N relay and 50/51G relay
网页2016年9月2日 · 50 and 51 are types of overcurrent relays (relays driven by a current transformer). Type 50 is an "instantaneous off" relay, whereas type 51 has an inbuilt time delay. The N, G, etc depicts not what the relay is, but how it is wired up .
