With voltage priority control features, these capacitor banks enhance voltage regulation and improve your system's voltage pass rate.

Technical Specifications

Main Features and Advantages

Our capacitor banks feature modular designs that ensure easy installation and maintenance. The robust steel enclosures protect sensitive components from environmental hazards and industrial contaminants. You'll appreciate the integrated current-limiting reactors that prevent dangerous resonance conditions.

Safety stands as our top priority. Each unit includes Kirk Key interlock systems and visual grounding switches. The unbalance detection schemes instantly isolate faults to protect your equipment and personnel. Advanced harmonic filtering capabilities ensure compliance with IEEE 519 standards.

The low-loss dielectric fluids in our capacitor units provide exceptional thermal stability. High-quality vacuum switches with pre-insertion resistors control inrush currents effectively. Our designs meet strict utility grid code requirements for seamless integration.

Practical Applications

Heavy Industrial & Metallurgy: Steel mills with Electric Arc Furnaces benefit from our harmonic-filtered metal enclosed capacitor banks. These units manage extreme load fluctuations while protecting against metallic dust contamination.

Renewable Energy: Wind and solar farms utilize our systems at substation levels for power factor regulation. They provide essential voltage support during generation variability periods.

Petrochemical Refineries: Large induction motor starting applications require substantial reactive power. Our explosion-proof designs operate safely in hazardous environments with flammable gases.

Commercial Buildings: Shopping centers and office complexes reduce utility penalties while improving electrical system efficiency.

How It Works

The system continuously monitors your facility's power factor through advanced control relays. When reactive power demand increases, the control system automatically switches capacitor steps online. This process maintains optimal power factor levels without manual intervention.

Current transformers provide real-time feedback to the control system. Protective relays monitor for overvoltage, overcurrent, and unbalance conditions. The integrated harmonic filters prevent resonance while maintaining power quality standards.

During switching operations, inrush current limiting reactors protect both the capacitors and your electrical system. The robust control logic ensures smooth operation across varying load conditions.
