A 1100V, 50Hz, delta connected induction motor has a starconnected slip ring rotor with a phase transformation ratio of 3.8.The rotor resistance and standstill leakage reactance per phase are0.012ohms and 0.25ohms respectively. Neglecting stator impedanceand magnetizing current determine the rotor current in Amperes atstart with slip rings shorted. Find the power factor at start withslip ring shorted.(round to the nearest whole number)
