Question

A load of 1000 kW at 0•8 power factor lagging is received at the end of a 3-phase line 20 km long. The resistance
and reactance of conductor are 0•25 Ω per km and 0•28 Ω per km. If the receiving end line voltage is maintained at
11 kV, calculate:
(i) Sending end voltage (line-to-line) (ii) percentage regulation and (iii) Transmission efficiency

Answer 1

Answer:

Sending end voltage (line-to-line(i) )
