ZDSVG-RVC Series Low-Voltage Reactive Power Compensation Cabinet (SVG)

The ZDSVGRVC lowvoltage reactive power compensation device is used in lowvoltage distribution networks of power systems. By compensating reactive power, it improves power factor, reduces line losses, optimizes voltage quality, and thus enhances power grid efficiency and operational stability of equipment.

It is widely applied in lowvoltage distribution systems in industrial, commercial building, and public facility fields, and particularly suitable for occasions with many inductive loads such as motors and transformers.

Features of LowVoltage Reactive Power Compensation Device

1. Improved Power Factor

Automatically compensates reactive power to raise the system power factor close to 1, reducing reactive current and lowering losses in lines and transformers.

2. Dynamic Compensation Capability

Adopts Thyristor Switched Capacitor (TSC) technology for millisecondlevel fast response, adapting to frequently fluctuating loads.

3. Modular Design

Supports modular combination, allowing flexible configuration of compensation capacity according to actual demands, facilitating later capacity expansion and maintenance.

4. Intelligent Control and Protection

Builtin intelligent controller monitors voltage, current, power factor and other parameters in real time, automatically switches capacitor banks, and provides overvoltage, undervoltage, overcurrent, overtemperature and other protection functions.

5. Energy Saving and Consumption Reduction

Reduces line losses and transformer copper losses caused by reactive power, significantly cutting power consumption and electricity costs.

6. High Reliability

Uses highquality capacitors and hightemperature resistant components with heat dissipation design, ensuring longterm stable operation in harsh environments.

7. Multiple Compensation Modes

Supports threephase common compensation, phasesplit compensation or hybrid compensation, adapting to threephase unbalanced loads and improving compensation accuracy.

8. UserFriendly HMI

Equipped with LCD or touch screen, displaying realtime operating parameters and alarm information, supporting manual/auto mode switching and parameter setting.

9. Active Filtering Function

Within its rated capacity, the static var generator actively filters odd and even harmonic currents from the 2nd to 50th order, preventing harmonic damage to capacitors and improving system power quality.

10. LowNoise Operation

Adopts contactless switching technology with low operating noise, suitable for noisesensitive locations.

11. Remote Monitoring and Communication

Supports communication interfaces including RS485, Modbus and Ethernet, connectable to SCADA or intelligent operation and maintenance platforms for remote monitoring and data analysis.

12. Easy Installation and Maintenance

Compact structure for compact cabinet installation; modular replacement enables quick repair during maintenance, reducing power outage time.

13. Environmental Protection and Safety

Uses dry selfhealing capacitors with no oil leakage risk, meeting environmental requirements; equipped with discharge resistors for fast and safe discharge after power failure.

14. Extended Equipment Service Life

Improves voltage quality and reduces equipment degradation caused by voltage fluctuations or harmonics, extending the service life of motors, transformers and other devices.

15. Compliance with Industry Standards

Meets international and domestic standards such as IEC and GB, and passes strict tests including EMC, voltage withstand and temperature rise, ensuring safety and compatibility.
