Compensation Panel

Reactive Power Compensation — Improve Energy Efficiency, Reduce Costs

Compensation Panel

Compensation panels are systems that improve the power factor (cos φ) by balancing reactive power in electrical installations. Motors, transformers and other inductive loads used in industrial facilities consume reactive power; this both increases energy bills and negatively affects the electrical infrastructure.

Botex System compensation panels instantly balance reactive power consumption through automatically activated capacitor banks. This eliminates reactive power penalty payments and improves energy efficiency.

Thanks to the automatic power factor regulator (APFC), the system continuously maintains the optimum power factor by activating and deactivating capacitor banks according to changing load conditions.

Frequently Asked Questions

Questions and answers about Compensation Panel

How much penalty will I pay without a compensation panel?+
TEDAŞ charges reactive energy fees from businesses whose power factor falls below 0.90. In medium and large-scale factories, this penalty can reach 15-30% of the monthly energy bill. With the installation of a compensation panel, this payment is completely eliminated and the investment usually pays for itself in 6-18 months.
How many kVAr compensation panel is needed?+
The required compensation capacity is calculated based on the total reactive power consumption, transformer power and current power factor at your facility. As Botex System, we perform the needs analysis free of charge by measuring energy on-site and determine the correct capacity. Incorrect sizing makes the system inefficient.
What is the difference between automatic and manual compensation?+
In manual compensation, capacitors remain in fixed circuit; it cannot adapt to changing load conditions and there is a risk of over-compensation. Automatic compensation systems maintain optimum power factor in all conditions by activating and deactivating capacitor groups according to the instantaneous load status through the APFC regulator. Botex System only installs automatic systems.
Does a compensation panel cause harmonic problems?+
Standard capacitor banks can create resonance in harmonic environments. To prevent this risk, we use detuned reactors with harmonic filtering. Botex System compensation panels include p=7% and p=14% harmonic filtering reactors as standard; this completely eliminates the risk of harmonic amplification.
How often should compensation panel maintenance be done?+
The compensation panel should be periodically maintained once a year. During maintenance, capacitor capacity is measured, connections are checked, reactors and APFC regulator are tested. Capacitors that are not regularly maintained lose their capacity over time and the system starts to work inefficiently.
