In the ever-evolving world of electrical engineering, maintaining an optimal power factor is key to achieving energy efficiency. With increasing demands on electrical systems, Power Factor Correction (PFC) has become a necessity. Eaton, a renowned name in power management, has designed a Power Factor Correction Calculator to aid professionals in this arena. This technical blog aims to shed light on this invaluable tool.

What is Power Factor Correction?

Power Factor Correction is a technique to align electrical current and voltage, thereby improving efficiency. In many systems, especially those with inductive loads like motors and transformers, the power factor can drift, causing inefficient operation.
