View ProductWhat Is Power Factor Correction and Why Does It Matter?
Power factor correction improves electrical efficiency by reducing reactive power in a system, ensuring that more of the supplied electricity is effectively used for productive work.
Without correction, industrial facilities draw excess reactive power, which leads to:
- Higher electricity bills
- Utility penalty charges from KPLC
- Overloaded transformers and cables
- Reduced equipment lifespan
In Kenya’s industrial zones, poor power factor is a common issue due to heavy motor loads and aging electrical infrastructure.
What Are the Best Power Factor Correction Solutions?
The best power factor correction solutions include APFC panels, capacitor banks, and hybrid correction systems designed to automatically balance reactive power in real time.
