Verified Answer
Calculate the time of operation of an IDMT type over-current relay is ...
Given, plug setting =125%
TMS=O.G
Fault current, If=4000A
Pick up current, I PK= plug setting × C.T. secondary current=1.25×1=1.25
Plug Setting multiplier,
Now, time of operation of any relay,
T=TMS x (Time calculated from IDMT table corresponding)
T = 0.6 x 3.3 = 1.98 sec
