Will the relay protection still activate after it is deactivated

Relays Part 3

If the relay is activated/ deactivated repeatedly, there''s a maximum operation rate that can be achieved. This is imposed by the feed circuit (R1, C1), and if you don''t wait long enough for C1 to discharge, the

Protective relay

OverviewOperation principlesTypes according to constructionRelays by functionsPower source

In electrical engineering, a protective relay is a relay device designed to trip a circuit breaker when a fault is detected. 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, overvoltage, reverse power flow, over-frequency, and under-frequency.
