| Model NO. | On-load Voltage & Reactive Power Regulation System |
| Rated voltage | 6/10/35kV |
| Rated frequency | 50Hz |
| Series | RWTBB |
The RWTBB series on-load voltage and reactive power regulation system is designed for substations with voltage levels ranging from 6 kV to 220 kV, installed on 6 kV / 10 kV / 35 kV busbars.By integrating on-load tap changer (OLTC) control and reactive power compensation, the device provides comprehensive voltage and power factor management for modern power distribution networks.
The RWTBB voltage-regulating and capacity-adjustable high-voltage reactive power compensation device is designed for 6kV-220kV power systems and installed on 6kV/10kV/35kV busbars in substations.
It is widely used in power utilities, metallurgy, coal mining, petrochemical industries and other high-voltage networks to improve voltage stability, increase power factor, and reduce system losses.
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.
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.
