Technical Specifications

Main Features and Advantages

Superior Voltage Regulation

Your power system benefits from automatic reactive power compensation that maintains voltage stability across transmission networks. Our banks prevent voltage collapse during peak load conditions.

Enhanced Transmission Capacity

By correcting power factor at strategic points, you can free up thermal capacity on transformers and transmission lines, allowing more active power transfer without infrastructure upgrades.

Reduced System Losses

Our high-efficiency design significantly lowers I²R losses across long-distance conductors, directly reducing your operational costs and improving grid efficiency.

Harmonic Management

Advanced detuning reactor integration protects against resonance while filtering harmful harmonics from your electrical system.

Modular Design

Stack-rack configurations allow you to expand capacity as your power demands grow, providing excellent scalability for future needs.

Practical Applications

HVDC Converter Stations

Our banks serve dual purposes in HVDC systems - providing essential reactive power for thyristor valve commutation while acting as AC harmonic filters to ensure stable DC link operation.

Long-Distance Transmission Corridors

Perfect for intermediate substations where voltage naturally degrades due to line impedance. Our outdoor-rated units withstand extreme environmental conditions while delivering reliable VAR support.

Renewable Energy Integration

Wind and solar farms connecting to transmission grids require precise power factor control. Our solutions ensure Grid Code compliance for Low Voltage Ride Through requirements.

Industrial Substations

Heavy industrial facilities with large inductive loads benefit from our banks' ability to provide local reactive power, reducing utility penalties and improving overall power quality.

How It Works

Your transmission capacitor bank operates by storing electrical energy and injecting leading reactive power into the network. When inductive loads create lagging power factor, our capacitors provide the necessary reactive current to balance the system.

The bank's sophisticated control system monitors voltage levels and automatically switches capacitor units in and out of service as needed. This dynamic response ensures optimal power factor correction while maintaining voltage stability throughout your transmission network.

FAQ

Q: How do you prevent harmonic resonance issues?

A: We perform detailed harmonic analysis and integrate detuning reactors (typically 6% or 7% impedance) to shift resonance points away from dominant grid harmonics.

Q: What maintenance is required?

A: Routine maintenance includes infrared thermography scans, visual inspections for capacitor bulging, leak checks, and verification of protection relay functionality.

Q: What's the expected lifespan?

A: With proper operation within rated parameters, you can expect 20-30 years of reliable service from our units.

Q: How do you handle switching transients?

A: We install current limiting reactors and recommend circuit breakers with pre-insertion resistors or point-on-wave switching controllers.

Q: What fusing technology is best for my application?

A: For voltages above 35kV, we typically recommend fuseless designs for maximum reliability, while internally fused units work well for lower voltage applications.
