How the System Works
The VS-ZGF500-30 converts AC input power into high-frequency voltage through the intelligent control unit. The high-frequency voltage is then stepped up and rectified by the high-voltage multiplier tower to generate a stable DC high-voltage output.
During testing, the integrated optical fiber microammeter measures leakage current directly at the high-voltage side and transmits the measurement data to the control unit through optical fiber communication. The intelligent controller continuously monitors voltage and current conditions while providing automatic protection against overvoltage, overcurrent, and flashover events.
