GIS AC Withstand Voltage and Partial Discharge Test Equipment for GIS Commissioning – High Voltage Resonant Test System for Substations

The GIS AC Withstand Voltage and Partial Discharge Test Equipment is designed for electrical substations where GIS commissioning requires both high-voltage insulation testing and partial discharge diagnostics.

GIS commissioning is a critical stage because transportation, installation, assembly and site conditions can potentially affect insulation performance. A combined HV and PD test provides engineers with more information than a simple withstand test.

1. AC Withstand Voltage Test

   Apply the specified AC test voltage to evaluate GIS dielectric strength.

2. Partial Discharge Measurement

   Detect and analyze localized discharge activity during or around the high-voltage test.

3. PDIV/PDEV Measurement

   Determine the voltage at which PD begins and the voltage at which it disappears.

4. PRPD Analysis

   Display discharge activity according to phase position and amplitude to assist defect diagnosis.

5. Test Data Recording

   Store voltage, current, discharge and test-time information.

6. Automatic Test Report

   Generate test reports for commissioning and customer acceptance.
