Main Features and Advantages
Superior Current Limitation Technology
Our advanced design incorporates inrush current limiting reactors that restrict instantaneous switching currents to less than 20 times the rated capacity, protecting your switchgear and extending equipment lifespan.
Precision Capacitance Control
Each unit maintains capacitance within 0-10% of rated values, with maximum variation between terminals under 1.06 ratio, ensuring consistent performance and predictable power factor correction.
Robust Overvoltage Handling
Built to withstand continuous operation at 110% rated voltage and temporary peaks up to 120% with harmonic content, providing exceptional reliability in unstable grid conditions.
Flexible Configuration Options
Available in both fixed and automatic switching configurations, our mv capacitor bank systems adapt to your specific load patterns and power factor requirements.
Practical Applications
Industrial Manufacturing
Perfect for steel mills, cement plants, and mining operations where large inductive loads demand robust reactive power support. Our enclosed designs handle dusty, high-vibration environments while paired with detuning reactors to prevent harmonic resonance.
Utility Distribution Networks
Grid operators rely on our open-rack configurations to maintain voltage profiles along transmission lines, featuring high-reliability fuseless designs that minimize maintenance interruptions.
Renewable Energy Integration
Wind and solar farms utilize our dynamic switching capabilities to meet strict grid code requirements at point of interconnection, managing rapid generation fluctuations effectively.
How It Works
Your mv capacitor bank operates by storing and releasing electrical energy in capacitive elements that generate leading reactive power. When inductive loads create lagging power factor, the capacitors automatically provide the necessary reactive power to achieve optimal power factor levels.
The system continuously monitors grid conditions through integrated protection relays. Automatic variants use vacuum contactors controlled by power factor controllers to step capacitance in or out based on real-time demand, preventing over-correction during light load periods.

FAQ
Q: How do I prevent harmonic resonance with my new capacitor bank?
A: We recommend installing detuned reactors rated at 6%, 7%, or 13% in series with capacitors. This shifts resonance frequency below dominant grid harmonics, preventing amplification and protecting your investment.
Q: What's the expected lifespan of these units?
A: Under normal operating conditions with proper maintenance, our design life typically reaches 20 years. Regular annual inspections help ensure optimal performance throughout this period.
Q: Should I choose internal or external fusing?
A: For large installations, internal fuses offer superior availability. They isolate only faulty elements while allowing continued operation with minimal capacity loss, unlike external fuses that disconnect entire units.
Q: What maintenance is required?
A: Maintenance is minimal but essential. Annual visual inspections, connection torque verification, protection relay testing, and insulator cleaning ensure reliable long-term operation.
