1.	The starting method for a 3-phase squirrel-cage induction motor which is inferior in view of poor starting torque per ampere of line current drawn is?(a) series-inductor method of starting(b) direct-on-line starting(c) auto-transformer method(d) star-delta methodThis question was posed to me at a job interview.My question is taken from Principle of Operation in portion Induction Machines of Electrical Machines
Answer» Right answer is (a) series-inductor method of STARTING Easiest explanation: DUE to inductor method, REACTANCE INCREASES and the starting TORQUE decreases.
