Description
Product Description

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.

Key Testing Functions
  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.

Customer Benefits
  • Faster commissioning workflow
  • Reduced need for multiple separate systems
  • Improved insulation diagnosis
  • Suitable for indoor and outdoor substations
  • Modular configuration
  • Customized test voltage and capacity
  • Professional technical support
FAQ
Can this system be used after GIS installation?
Yes. GIS high-voltage testing systems can be designed for on-site commissioning applications.
Can it test GIS without removing the insulating gas?
The answer depends on the test system architecture and GIS configuration. Some specialized resonance systems are specifically designed to interface with GIS through existing voltage transformers without draining and refilling the insulating gas.
Is PD testing mandatory for every project?
Testing requirements depend on the applicable standard, project specification, GIS manufacturer and utility requirements. The customer's project specification should always be checked before selecting the test procedure.
