Determine the time of operation of 5A , 3 Seconds overcurrent relay having a current setting of 150% and a time setting multiplier of 0.8 connected to supply circuit through a 500/5 current transformer when the circuit carries a fualt current of 5000A. (If plug setting multiplier comes to be less than 5, then time of operation is 2.5 seconds and if plug setting multiplier comes to be less than 5, then time of operation is 3.5 seconds.)
