This equipment can make on line current measurement for the net work capacitors, regulate the load switch positions of the arc-eliminating coils to make the inductance current in the arc-eliminating coils offset with the current in the earthened capacitors. With the connection of a damping resistor, it can make over? Compensation, less-compensation and full-compensation for the capacitor current. It can not only minimize the earth remaining current but also prohibit voltage resonance in the network.

From the panel of the equipment, the net work off resonance, network capacitor current, neutral point asymmetrical voltage, neutral point voltage, reactance numbers etc. Can be displayed at any time. Manual and automatic operation buttons are installed and the automatic operation can be selected to the automatic tuning and tracing position for the no-man-on-duty stations.
