Technical Specifications

Main Features and Advantages

Self-Healing Technology: Our capacitors feature advanced self-healing properties that automatically isolate internal breakdowns, ensuring continuous operation and extended service life.

Superior Dielectric System: The all-film polypropylene construction with biodegradable synthetic fluid provides excellent partial discharge resistance and environmental safety.

Flexible Configuration Options: Available in both internally fused and externally fused configurations to match your specific application requirements and budget considerations.

Robust Protection: Internal discharge resistors safely reduce residual voltage, while specialized fusing technology prevents tank rupture during fault conditions.

Low Maintenance Design: Engineered for minimal maintenance with annual inspection schedules and predictable 15-20 year service life under proper operating conditions.

Harmonic Resilience: Optional detuned reactor configurations protect against harmonic amplification in networks with non-linear loads.

Practical Applications

Your 11 kv capacitor bank serves multiple critical applications across various industries. Distribution substations use these systems to maintain optimal power factor and reduce transmission losses. Heavy industrial facilities rely on them to offset reactive power from large induction motors and transformers.

Manufacturing plants benefit from reduced utility power factor penalties and improved voltage stability during peak demand periods. Mining operations use these banks to support arc furnaces and large motor drives. Commercial buildings integrate them into their electrical infrastructure to maximize transformer capacity utilization.

Power generation facilities employ these systems to optimize grid connection efficiency. Water treatment plants use them to support pump motor operations and maintain stable voltage profiles.

How It Works

Your system operates by providing leading reactive current that neutralizes the lagging inductive current from motors, transformers, and other inductive loads. Multiple capacitor units connect in star or double-star configurations to inject reactive power (kVAR) directly into your electrical network.

The capacitor bank automatically responds to changing load conditions, providing reactive power compensation where and when you need it most. This local reactive power source reduces the burden on your supply grid and improves overall system efficiency.

Advanced control systems monitor power factor continuously and switch capacitor steps as needed. Protection relays guard against over-voltage, unbalance, and harmonic conditions that could damage the equipment.

FAQ

Q: What's the difference between internally and externally fused units?

A: Internally fused units isolate individual faulty elements while maintaining operation, ideal for larger banks. Externally fused units disconnect the entire unit during faults - simpler and more economical for smaller installations.

Q: Do I need reactors with my capacitor bank?

A: If your system has variable frequency drives or UPS equipment, reactors prevent harmonic resonance that could damage capacitors. We recommend 6% or 7% detuned reactors for such applications.

Q: How long do these capacitor banks last?

A: With proper installation and maintenance, expect 15-20 years of service life. Operating temperature and harmonic exposure are the primary factors affecting longevity.

Q: What maintenance do these units require?

A: Annual visual inspections, thermal imaging for connection integrity, and capacitance measurements. Our maintenance guidelines ensure optimal performance throughout the service life.
