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

  Re: What is meant by inverse definite mean time (IDMT)& definitemean time (DMT)?
Answer
# 1
The definite mean time lag in disc type EM relays is inverse
to current as the disc is faster at higher current and hence
the less time.Definite mean time lag is possible in static
relays by setting the time lag.

Answer
# 2
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.
