Description
Product Description

The GIS Partial Discharge Test System is designed for sensitive insulation diagnostics where low background noise and reliable PD measurement are critical.

Partial discharge can be caused by defects such as metallic particles, insulation damage, surface contamination, protrusions, floating electrodes and other localized insulation problems.

The system combines high-voltage AC excitation with a PD measurement chain for detecting and analyzing discharge activity.

Main Functions
  • Partial discharge measurement
  • AC withstand voltage test
  • PD inception voltage
  • PD extinction voltage
  • PD magnitude measurement
  • Phase-resolved PD pattern
  • Noise identification
  • Digital data acquisition
  • Waveform recording
  • Test report generation
Low Background PD

Low background noise is particularly important when measuring small PD signals.

Industry GIS systems emphasize low PD background, with some systems specifying values below 10 pC or even lower depending on configuration and test conditions.

Applications
  • GIS
  • GIL
  • Transformers
  • Instrument transformers
  • Switchgear
  • Bushings
  • Insulators
  • Cables
Customer Pain Points

PD signal is too weak

The measurement system should have appropriate sensitivity, shielding, grounding and filtering.

Too much external interference

The testing environment, grounding arrangement, coupling method and measurement bandwidth all influence PD measurement quality.

Customer needs repeatable test results

Digital acquisition and standardized test procedures can improve repeatability.

FAQ

Q: What is partial discharge?

A: Partial discharge is a localized electrical discharge that does not completely bridge the insulation between conductors.

Q: Why is low background PD important?

A: Lower background interference makes it easier to distinguish actual discharge activity from external noise.

Q: Can you provide a PD measurement system together with the AC test system?

A: Yes. The complete solution can integrate the AC high-voltage source, coupling system, PD detector, measuring system and control software.
