What are the disadvantages of Low power factor?

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.
