A single phase overhead transmission line delivers 4000 kW at 11 kV at 0·8 p.f. lagging. If resistance and reactance per conductor are 0·15 Ω and 0·02 Ω respectively, calculate:
(i) percentage regulation
(ii) sending end power factor
(iii) line losses
(i) Percentage regulation,
(ii) Sending end power factor,
(iii) Line loss,
