The secondary winding of a transformer has a terminal voltage of vsec (t) = 234 sin (377t) V. The turns ratio of the transformer (N1/N2) is 72:201. If the secondary current of the transformer isec (t) = 12 sin(377t+ [25°]), (a) What is the RMS value of the primary current of this transformer? (b) What are its voltage reg- ulation and (c) efficiency? The impedances of this transformer referred to the primary side are Rsc = 0.292, Xsc = 0.752 and Re=30092, Xm = 709.
