APFC Capacitor Guide for Power Factor Improvement
Introduction to APFC Capacitor Systems
An APFC capacitor (Automatic Power Factor Correction capacitor) is used to automatically improve the power factor in electrical systems. In modern industrial and commercial environments, poor power factor leads to energy losses and higher electricity costs. Using an APFC capacitor helps maintain efficiency, stabilize voltage, and optimize energy usage.
Understanding Power Factor and Correction
Power factor represents how effectively electrical power is used.
Common causes of poor power factor include:
- Inductive loads
- Motors and transformers
- Industrial equipment
A correction system helps balance reactive and active power.
