We have 800KW motor operating at 6600Volt,50 Hz supply.During 1st startup it tripped on overcurrent trip.It's FLA is 88 Amps.The K factor of Thermal overloaaad was set on .94 initially.then we set at 0.97 and then it started fine.i dont understand why it tripped first?What are the protections which comes in picture during starting ?
