A 200 KVA single-phase transformer with a voltage ratio 6350/660 V has the following winding resistances and reactances:
Rp = 1.56 12, Rs = 0.016 Q, Xp = 4.67 , Xs = 0.048 0.
On no load the transformer takes a current of 0.96 A at a power factor of 0.263 lagging. Calculate the equivalent circuit parameters referred to the high- voltage winding.
Using the data above, calculate approximately the inherent voltage regulation at a power factor of:
(a) 1
(b) 0.8 lagging
(c) 0.8 leading
