Can you explain operating principle of Inverse Definite Minimum Time” (IDMT) relay..

Answer / naresh

it is the combination of inverse & definite time
characterstics.......

in inv time cahr relay the time of operation is inversely
proportional to fault current i.e, more fault current less
operation time......

in definite time irrespective of fault current the time is
constant....

in the above question the time will be varying inversely to
some extent and after saturation of the relay coil it is
having the properties of definite time relay....
