A single-phase 10 kVA, 2300/230V two-winding transformer is connected as an autotransformer to step up the voltage from 2300 to 2530V.
a. Draw the schematic diagram of the autotransformer showing the winding connections and all voltages and currents at full-load.
b. Find the kVA rating of the autotransformer. Do not allow the currents of windings to exceed their rated values.
