MCQ
+2 marks
-0.66 marks
A 50kVA, 400V, 3-phase, 50Hz squirrel cage induction motor has full load slip of 5%. Its standstill impedance is 0.866 ohms/phase. It is started using a tapped autotransformer. It the maximum allowable supply current at the time of starting is 100A, then calculate the tap position and the ratio of starting torque to full load torque
