What is meant by inverse definite mean time (IDMT)&
definitemean time (DMT)?

Answer Posted / m.k.k

idmt means inverse definite minimum time. so in this type of
relay as the value of operand that is current increase time
taken by the relay to operate decrease. higher the current
lower is the time taken by the relay to operate. AND dmt
definite minimum time (DMT) relay take its minimum time to
operate regardless of the value of the current.
