Description
PDS-GIS is a professional full-size GIS partial discharge simulation test platform designed for partial discharge mechanism research, detection equipment performance verification, operator skill training and PD fingerprint database establishment in power research institutes, universities, high-voltage equipment manufacturers, power training centers and third-party testing institutions. It strictly complies with IEC 60270, GB/T 7354-2003 and DL/T 1630-2016 standards, adopting a horizontally arranged true GIS sealed chamber filled with SF₆ gas that truly restores the internal insulation structure and operating environment of actual GIS equipment.
The system integrates 5 classic GIS insulation defect models including metal tip, floating potential, internal air gap, free metal particle and insulator surface discharge, with continuously adjustable discharge magnitude and good repeatability. Its ultra-low background partial discharge (≤1pC) ensures the authenticity and accuracy of test signals. It is fully compatible with mainstream PD detection methods including pulse current method, ultra-high frequency (UHF) method, ultrasonic method and high frequency current transformer (HFCT) method, with reserved standard interfaces for various sensors, supporting comparative test and multi-method joint detection research.

FAQ
Q: What types of GIS partial discharge defects can this system simulate?
A: PDS-GIS integrates 5 classic GIS insulation defect models, covering almost all common fault types in actual operation:
- Metal tip discharge: simulates conductor burrs and installation scratches
- Floating potential discharge: simulates ungrounded metal components
- Internal air gap discharge: simulates epoxy insulator internal manufacturing voids
- Free metal particle discharge: simulates conductive contaminants left during installation
- Insulator surface discharge: simulates surface contamination and moisture faults Each defect can be independently switched, and also supports composite defect superposition test.
Q: What is the significance of ≤1pC background partial discharge?
A: Background discharge is the inherent discharge of the test system itself. If the background is too high, it will submerge the weak defect signal and affect the authenticity and accuracy of the test. The ≤1pC ultra-low background of PDS-GIS can ensure that the detected signal completely comes from the defect model, and can stably detect micro-discharge as low as 0.1pC, which meets the requirements of high-sensitivity test and equipment calibration.
Q: Which partial discharge detection methods can be supported?
A: The system fully supports 4 mainstream GIS PD detection methods:
- Pulse current method: standard IEC 60270 quantitative detection
- UHF method: ultra-high frequency electromagnetic wave detection
- Ultrasonic method: acoustic vibration detection
- HFCT method: high frequency current detection on grounding wire Reserved standard installation interfaces for each detection method, which can be used with various brands of PD testers for calibration and comparative test.
Q: Can this system be used to calibrate partial discharge testers?
A: Yes. PDS-GIS is equipped with a standard pulse injection port, which can be connected to a PD calibrator for quantitative calibration. The discharge magnitude of each defect model is continuously adjustable and has good repeatability, which can be used as a standard signal source to verify the detection sensitivity, measurement accuracy and defect recognition ability of various PD testers.
