Question: A 1 0 0 kVA, 2 0 0 0 / 2 0 0 V , single phase two winding transformer is to be used as

A 100kVA, 2000/200V, single phase two winding transformer is to be used as an auto transformer to step up the voltage from 2000V to 2200V. At the rated load, the two winding transformer has 2.5% loss, 3% voltage regulation and 4% impedance. For the autotransformer, determine: Voltage and Current Rating, kVA rating, efficiency, percentage impedance and regulation.
