The parameters for a 250-kVA, 2400-480V, single phase transformer operating at a rated voltage, rated kVA, and 0.82 power factor lagging, are Xeq,hs=1.08Ω and Req,hs=0.123Ω. The transformer is operating in the step-down mode. Sketch the appropriate equivalent circuit and determine (a) the equivalent low-side parameters; (b)the no-load voltage; (c)the voltage regulation at 0.82 power-factor lagging.
