SOLVED: A single-phase 10-kVA 480/120-V transformer is to be used as an autotransformer tying a 600-V distribution line to a 480-V load. When it is tested as a conventional transformer, the following values are measured on the primary (480-V side) of the transformer: Open-circuit test: Voc = 480V, Short-circuit test: Vsc = 10.0V, loc = 0.41A, Isc = 10.6A, Psc = 38W. Find the per-unit equivalent circuit of the transformer when it is connected in the conventional manner. What is the efficiency of
