(1) A 3-phase squirrel-cage induction motor takes 175% of full-load line current and develops 35% of full-load torque at starting when operated by a star-delta switch. Estimate the full-load slip. What would be the starting torque (as a percentage of the full-load torque), supply and motor line currents (each as a percentage of full-load line current) if an auto-transformer starter with 80% tapping were employed?
