A factory has an electrical load of 1600 kW at a lagging powerfactor of 0.8. An additional variable power factor load is to be added tothe factory. The new load will add 320 kW to the real power load of thefactory. The power factor of the added load is to be adjusted so that theoverall power factor of the factory is 0.96 lagging. Assume the factory described above is fed from a linehaving an impedance of 0.05+j0.4 Ω. The voltage at the factory ismaintained at 2400 V(rms). 1. a) Find the average power loss in the line before and after the loadis added.2. b) Find the magnitude of the voltage at the sending end of the linebefore and after the load is added.

Question

A factory has an electrical load of 1600 kW at a lagging power
factor of 0.8. An additional variable power factor load is to be added to
the factory. The new load will add 320 kW to the real power load of the
factory. The power factor of the added load is to be adjusted so that the
overall power factor of the factory is 0.96 lagging.

Assume the factory described above is fed from a line
having an impedance of 0.05+j0.4 Ω. The voltage at the factory is
maintained at 2400 V(rms).

1. a) Find the average power loss in the line before and after the load
is added.
2. b) Find the magnitude of the voltage at the sending end of the line
before and after the load is added.
