ZBWKG-3000 High Voltage Reactive Power Compensation Controller adopts 16-bit single-chip microcomputer chip, AC sampling technology, LCD Chinese display, quadrant analysis and other technologies, realizes real-time data collection, communication, power statistics, historical data storage, fault alarm, grid harmonic analysis, reactive power compensation and other functions, and can be directly connected to the computer for online operation. The high-voltage reactive power compensation controller can control the automatic switching of the reactive power compensation capacitor group according to the parameters of the grid. Make the capacitor work in the best condition, ensure that the voltage qualification rate meets the requirements, effectively reduce the reactive power loss and keep the system power factor in a high range.
