What is the power factor, why does it need to be maintained, what power quantity or quality does it impact, and how can this impact be observed?

Question

Accepted Answer

Power factor is the ratio of real power to apparent power in an electrical system. It needs to be maintained for efficient power transfer and to avoid penalties from utility companies.

Power factor impacts the efficiency of power transfer in electrical systems
Low power factor can result in higher energy costs and penalties from utility companies
It affects the quality of power supply and can lead to voltage drops and equipment overheating
Power factor can be improved by using power factor correction devices such as capacitors
Maintaining a high power factor ensures optimal use of electrical power and reduces energy wastage
