Earth leakage relay là gì

WebUnlike on an earth leakage breaker, there is no interruption performed and there is only an earth leakage detection function. Detection of the earth leakage is performed (ZCT) and then a signal is sent when there is earth leakage (relay part). It is used with a combination of a ZCT (zero-phase current transformer) and a relay.
