Answer Posted / klm
It is inverse in the sense , the tripping time will decrease as the magnitude of fault current increase.
simply saying,
"for a fault current of 25KA-the time delay may be 2s.
& for a fault current of 30KA the tme delay may be 1.5s.thus as the fault current increases the time delay decreases.
