Functional features

Automatic control of reactive power compensation for power capacitor bank in 6-35kV double section bus operation system

Color LCD display in Chinese / English

Automatically identify and adapt to the operation mode of single and double variable system

Two control strategies of voltage reactive power and power factor

8-channel capacitor bank control output, 5-channel protection output

Fault input, switch position signal, external switch status, temperature alarm signal, etc

It includes the whole point record, SOE, switching record, capacitor switching frequency and practice, fault locking information, input record, etc

Over voltage protection, under voltage protection, voltage harmonic out of limit protection, refuse to operate, capacitor fault locking and other protection functions

RS485, RS232 dual port communication function, background communication function, "four remote" function

Display bus voltage, current, active power, reactive power, power factor and capacitor bank status

Display system protection, capacitor protection feedback, front switch off information and other alarm protection information

The data and bar graph show the 27th voltage, current harmonics and total distortion rate
