The current measurement transformer uses a sampling current transformer with easy installation and high reliability, which improves the installation quality, aging resistance, lightning resistance and long life. It has perfect protection functions such as over-voltage, under-voltage, harmonics, over-current, and current unbalance.

It can realize the multi-level automatic switching control function, make the reactive power compensation curve of the high-voltage line smoother and better, and adopt reliable microprocessor and control technology to realize the automatic control, data statistics and storage functions of the compensation system.

The purpose of long-distance data collection and control is realized through GPRS remote wireless communication, and the special vacuum contactor for switching capacitor is used as the switching switch, which is suitable for on-off capacitive current and has higher reliability.

There are five automatic compensation methods: 1 dynamic compensation, 1 static compensation + 1 dynamic compensation, 1 static compensation + 2 dynamic compensation, 2 dynamic compensation, 3 dynamic compensation, and the total compensation capacity of this compensation device can be 50kvar-900kvar.
