Mention the disadvantages of low power factor? How can it be improved?
Disadvantages of low power factor :
Line losses are 1.57 times unity power factor.
Larger generators and transformers are 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.
