What are the disadvantages of Low power factor?


#1

Disadvantages of Low Power Factor

Line losses are 1.57 times unity power factor

Larger generators and transformers required

Low lagging power factor causes a large voltage drop,hence extra regulation equipment is required to keep voltage drop within prescribed limits.

Greater Conductor size -To transmit or distribute a fixed amount of power at fixed voltage,the conductors will have to carry more current at low power factor.This requires a large conductor size.
