Maximiser l'efficacité et le facteur de puissance
A Contrôleur de condensateurs à haute tension is an automatic device used in substations or industrial power systems to manage the switching of high voltage capacitor banks. Unlike basic protection relays, this controller continuously monitors grid parameters such as reactive power, voltage, and current. When the system detects lagging power factor or voltage drops, it sends commands to close or open circuit breakers connected to capacitor units. The goal is to maintain power factor within a target range (e.g., 0.92–0.99) without over-compensation. Most units operate at 6kV, 10kV, or 35kV levels and include communication ports for SCADA integration
| Fonction | Description |
|---|---|
| Automatic Power Factor Regulation | Measures real-time reactive power demand and switches capacitor steps accordingly to keep power factor above set threshold. |
| Voltage Monitoring & Control | Prevents over-voltage or under-voltage by adjusting capacitor bank status; supports line drop compensation. |
| Harmonic Detection | Identifies harmonic distortion levels (e.g., 5th, 7th, 11th) and blocks switching if harmonics exceed safe limits. |
| Manual Override | Allows operators to force capacitor switching via local HMI or remote commands for maintenance or emergency. |
| Event Logging | Records switching times, alarms, and electrical parameters for troubleshooting and load analysis. |
| Communication | Provides RS485 (Modbus RTU), Ethernet (Modbus TCP), or IEC 61850 for integration with energy management systems. |
This table helps engineers and procurement teams quickly match the high voltage capacitor controller to their system requirements.

Where a High Voltage Capacitor Controller Makes the Difference
A capacitor bank alone won’t fix dynamic reactive power issues. You need a Contrôleur de condensateurs à haute tension to decide when and which capacitor step to switch. Below are real-world installations where our controller — paired with high voltage capacitors — cuts demand charges, stabilizes bus voltage under fluctuating loads, and prevents harmonic resonance that could damage other equipment.
Uses reactive power + voltage + time-of-day strategies, not just power factor. Avoids hunting between steps. This reduces mechanical wear on contactors and extends capacitor bank life by roughly 30%.
If total harmonic distortion (THD) rises above 12%, the controller locks out switching. Protects capacitors from overload. No external harmonic relay is needed, simplifying your panel wiring.
This high voltage capacitor controller works from -30°C to +60°C after custom coating. Used in steel plants, wind farms, and mining sites. The same controller can be deployed indoors or outdoors with optional IP54 enclosure.
The high voltage capacitor controller uses the same panel cutout and wiring layout as older Zhiming models. No need to redesign your switchgear. Typical replacement takes less than 40 minutes from power-off to restart.
Stores 90 days of power factor and switching events. Download via USB port (standard). Files are plain CSV – no proprietary software required for analysis.
Every controller comes with a 5-year warranty and access to Zhiming’s engineers for logic tuning. We also provide on-site training for your maintenance team within the first year of purchase.

Yes. The relay outputs are designed for 220V AC/DC coils. Just match the contactor coil voltage and current (≤5A resistive).
The controller will detect under-voltage (e.g., below 80% of nominal) and disable all outputs. An alarm LED lights up. No auto-closing occurs until voltage returns
No, but if your system has more than 20% THD at the PCC, the controller will block switching as a safety measure. You’d need a detuned filter bank for those cases.
Standard model handles up to 8 steps. Custom firmware supports 12 steps. Each step requires one relay output.
