Given: A 40 HP elevator motor fed from a 300 kVA transformer. Assume across-the-line starter and neglect line impedances, etc. The question has come up re. how does the motor starting voltage drop change from the unloaded transformer condition to the loaded transformer condition? Assume no load in the first case and, say, a 200 kVA steady state load for the second case.
