Power Factor

Last updated May 16, 2025, generated by Sumble

What is Power Factor?

Power factor is the ratio of real power (kW) to apparent power (kVA) in an electrical circuit. It represents how effectively electrical power is being used. A low power factor indicates that more current is needed to deliver the same amount of real power, leading to increased energy losses, higher electricity bills, and potential equipment overheating. Power factor correction techniques, such as using capacitors, are employed to improve the power factor, making the electrical system more efficient.
