In REF 615 ABB relay I have a dots . 1 what is operating delay time . 2 reset delay time . in our relays both time set to m sec

[@electricalulagam9334]

Thank you for your reply.... 1.operating delay time is original time multiplier(TMS) 2. Reset delay time is after fault tripping auto reset (relay output contact reset not LED) delay time.
