Mention the disadvantages of low power factor? How can it be improved?
by

1 Answer

Answer :

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.
