Return time after relay protection starts

The need to act quickly to protect circuits and equipment often requires protective relays to respond and trip a breaker within a few thousandths of a second. In some instances these clearance times are prescribed in legislation or operating rules. A time relay helps you choose when a device turns on or off. In the context of protective relays used in electrical systems, the resetting time is a critical parameter that determines how quickly the relay can resume its normal. Some customers ask me about the response time of a relay, But inside the catalogue,two different delays are mentioned: the switch-on and the switch-off delays of the relay.
