A single phase generator supplies an inductive load of 4800 KW at a power factor of 0.6 lagging by means of an overhead line which is 25 km long. The line resistance and inductance are respectively 0.02 and 0.58 m H per km. The voltage at the receiving end is to be kept constant at 10.5 KV. Find the sending end voltage and the voltage regulation of the line. (8)
