Question

A 440 V, three phase distribution feeder is supplying a load of 10 MVA with a lagging power factor. (a) If the load power factor is 0.85 lagging, how many

Mvars of shunt capacitors are required to increase the power factor of the load to 0.9 lagging? (b) If the load power factor is 0.9 lagging, how many Mvars of shunt capacitors are required to increase the power factor of the load to 0.95 lagging? (c) Which requires more reactive power, improving a low power factor load or a high power factor load?
