What is a power factor correction capacitor, and why is it used?

Question

Accepted Answer

A power factor correction capacitor improves the power factor in electrical systems, enhancing efficiency and reducing energy costs.

Improves Power Factor: Capacitors counteract inductive loads, helping to align voltage and current waveforms.
Reduces Energy Costs: By improving power factor, businesses can lower their electricity bills due to reduced demand charges.
Enhances System Capacity: Correcting power factor allows for more efficient use of existing electrical infrastructure.
Example: In industrial settings, motors and transformers often create a lagging power factor, which can be corrected using capacitors.
Compliance: Many utility companies require a minimum power factor; correction capacitors help meet these standards.
