Answer Posted / er. mohammed yusuf fahad
The IDMT Inverse definite minimum time relay is one such
type of relay where the delay time of the relay is
inversely proportional to the magnitude of the fault
current. For ex. If the fault current is of the magnitude
of 8KA the delay taken by the relay to tripp the ckt may be
3 sec likewise if a fault current of 16KA persists in the
system the IDMT delay time will automatically reduce to 1.5
sec and so on. It is used in applications of overcurrent
relays and earth fault relays.
