Determine the required tapping on the transformer, Electrical Engineering

Assignment Help:

An induction motor has a starting current that is 6 times the full-load current and a per-unit full- load slip of 0.04. The machine is to be provided with an autotransformer starter. If the minimum starting torque must be 0.3 times the full-load torque, determine the required tapping on the transformer and the per-unit supply-source line current at starting.
