ZD-GWJ Medium Voltage(3kV~24kV) group automatic reactive power compensation device automatically switches capacitor banks according to the voltage and reactive power of the power supply bus, and performs reactive power compensation by tracking load changes, thereby providing power factor, improving power supply quality, and reducing power consumption. It is often installed in front of the control cabinet of the high-voltage motor of the working condition enterprise for fixed compensation.

A high voltage group automatic reactive power compensation system is a technology used in electrical power systems to manage reactive power and improve power quality. Reactive power is a component of alternating current (AC) that does not perform useful work but is required for the operation of inductive loads such as motors, transformers, and magnetic coils.

This system includes capacitors and reactors that are connected in parallel or series with the power equipment to compensate for reactive power. The capacitors provide reactive power in lagging (inductive) mode to counterbalance the reactive power absorbed by inductive loads, while reactors provide reactive power in leading (capacitive) mode to compensate for excess capacitive reactive power.

Overall, a high voltage group automatic reactive power compensation system helps optimize power transmission and distribution, improves power quality, and reduces energy consumption and costs.
