Key Features
- Integrated Voltage & Reactive Power Control
Automatically adjusts transformer tap positions and capacitor compensation to maintain stable bus voltage and optimal power factor. - Flexible Configuration
Supports multiple compensation sections for precise and efficient reactive power management. - Improved System Efficiency
Reduces line losses, relieves transformer burden, and enhances overall grid power quality. - Smart Monitoring & Protection
Real-time monitoring of operating status and protections against over-voltage, over-current, unbalanced current and harmonic influence. - Extended Equipment Lifetime
Minimizes capacitor switching frequency and mitigates impact currents. - Adaptable for Harsh Industrial Environments
Suitable for heavy-load, large-capacity motor systems with frequent fluctuations.
Working Principle (Simplified)
The controller adjusts:
- Transformer voltage regulation
- Reactive compensation level via capacitor group switching
This ensures stable output voltage and proper reactive power balance across the distribution network.
