Hello friends,
I would like to know the difference between overvoltages & overcurrents. Which is more dangerous & why do we normally use an Inverse definite minimum time(IDMT) relay for an Overcurrent relay & a definite time relay for an over-voltage relay. Is this because that in case of overvoltages, in spite of heavy voltage there wouldn't be too much of a damage or what's the actual funda in the whole thing.
