Consider the arrangement of SQCIM in an industrial plant shown below.

1.)Determine the maximum continuous current that must be supplied by the utility to the plant (all motors are running). Determine also the % voltage loss through the transformer.

2.) Motor B has a severity factor of 7.2 and it is a design class B motor. Determine the starting torque and current of this motor for a direct on line start. Also determine the voltage dip due to the transformer reactance.

3.) Repeat 2, if a star to delta scheme is used for starting the motor.

Please don\'t mind it being upside down, i tried fixing it.

Solution

alternator is driving 4 motors

haveing different utility factor 1.2

Imax= V/(x1 + x2 + x0)
