Introduction to Power Factor Correction Capacitor
A power factor correction capacitor is an essential electrical component used to improve power efficiency by reducing reactive power in a system. In modern electrical networks, especially those with inductive loads like motors and transformers, power factor tends to drop, leading to energy losses and higher electricity costs.
Using a power factor correction capacitor helps optimize energy usage, stabilize voltage, and enhance overall system performance. This makes it a critical solution in industrial and commercial power systems.
What is a Power Factor Correction Capacitor
A power factor correction capacitor is designed to supply reactive power locally, reducing the burden on the power supply. It improves the power factor, which is the ratio of real power to apparent power in an electrical system.
A higher power factor means:
- Better energy efficiency
- Lower losses
- Reduced utility penalties
How a Power Factor Correction Capacitor Works
