What is Reactive Power Compensation? Benefits of Compensation Panels
Reactive power compensation is the process of improving the power factor by using capacitor banks to compensate for the reactive power drawn from the grid by inductive loads. This process both increases energy efficiency and prevents reactive energy penalties.
What is the Power Factor (Cosφ)?
The power factor is the ratio of active power to apparent power, indicating how much of the energy drawn from the grid is converted into useful work. The ideal value is close to 1. A low power factor leads to unnecessary current draw and line losses.
Benefits of Compensation Panels
- Preventing reactive energy penalties.
- Reduction in line and transformer losses.
- More efficient use of network capacity.
- Improvement in voltage drop.
Fixed and Automatic Compensation
While fixed-load compensation is sufficient for installations with a constant load, automatic compensation with a reactive power control relay is preferred for installations with a variable load. Reactor-based compensation is necessary for installations with high harmonic content.

Frequently Asked Questions
What is reactive power compensation?
This process improves the power factor and increases energy efficiency by using capacitors to counteract the reactive power drawn by inductive loads.
Why is a compensation panel necessary?
It prevents reactive energy penalties, reduces line and transformer losses, uses grid capacity efficiently, and improves voltage drop.
When is automatic compensation used?
In installations with variable loads, automatic compensation, where stages are automatically activated using a reactive power control relay, is preferred.
