A 10-kVA, 480/120-V, 1-Φ transformer is to be used as an autotransformer to transform a 600-V source to a 480-V supply. As a 1-Φ transformer delivering rated load at 0.90 power factor lagging, its efficiency is 0.96%a. show the connection diagram of an autotransformerb. determine the KVA rating as an autotranformerc. find the efficiency as an autotransformer deliverling rate capacity at 480 V and 0.80 power facing lagging
