A 25-kVA, 2500/250-V distribution transformer is connected as a stepup autotransformer, with the load connected to both the primary and secondary windings and the input connected to the secondary windings only. For this combination, draw the circuit diagram and determine:
a) the primary winding voltage,
b) the secondary winding voltage,
c) the voltage transformation ratio,
d) the nominal rating of the autotransformer.
