An autotransformer is used to connect a 12.6-kV distribution line to a 13.8-kV distribution line. It must be capable of handling 2000 kVA. There are three phases, connected Y-Y with their neutrals solidly grounded.

(a) What must the N_C/ N_SE turns ratio be to accomplish this connection?

(b) How much apparent power must the windings of each autotransformer handle?

(d) If one of the autotransformers were reconnected as an ordinary transformer, what would its ratings be?
