The partial discharge (PD) simulation device developed by our company features an integrated design that is user-friendly, compact, and portable. It incorporates five types of discharge modules—point-to-plane, floating potential, free particle, surface discharge, and internal gas gap. By utilizing SF6 as the insulating medium, the device achieves an extremely low PD background level, ensuring clear discharge waveforms. It is particularly suitable for training and research purposes in universities, research institutes, large-scale power equipment manufacturers, and provincial or municipal power supply companies.

It simulates various discharge phenomena within Gas-Insulated Switchgear (GIS), making it ideal for experimental research on live PD detection and the performance evaluation of detection instruments.
Product Features:
1. High-Fidelity Physical Structure
Designed based on actual industrial-grade GIS structures, it accurately replicates the internal electric field distribution and the evolution process of partial discharge.
2. Compact, Integrated Design
High-voltage components—such as the step-up transformer and coupling capacitor—are built directly into the GIS enclosure, ensuring high integration and robust safety protection.
3. Multi-dimensional Defect Simulation and Composite Modeling
Supports the simulation of typical faults such as free particles, floating potential, point discharge, internal gas gaps, and surface flashover, as well as the superimposed evolution of multiple fault modes.
4. Precisely Controllable Fault Parameters
Discharge types can be switched as needed, and parameters such as inception voltage, extinction voltage, and discharge amplitude can be quantitatively adjusted for each discharge type.
5. Fully Compatible Detection Interfaces
Provides a complete set of standard test interfaces for mainstream detection methods, including the pulse current method, Ultra-High Frequency (UHF), Acoustic Emission (AE), High Frequency (HF), and SF6 decomposition product analysis.

6. Traceability and Standard Calibration
Features built-in coupling and calibration units for the pulse current method, supporting multi-parameter synchronous measurement and metrological verification.
7. High Reproducibility and Long-term Stability
Each fault simulation module is designed for durability and repeated use, maintaining highly stable physical characteristics of the discharge pulses.
8. Simplified External Control
Fault states can be triggered, adjusted, and cleared from outside the device without the need to disassemble the main structure. 9. Diverse specifications of basin-type insulators
Equipped with various types of basin insulators—including fully shielded, bare basin, and casting-port designs—to meet diverse testing requirements.
10. Visual monitoring of fault conditions
Integrated infrared and video monitoring probes allow for real-time observation of the internal chamber and dynamic capture of optical and electrical images during partial discharge events.
11. Integrated sensor comparison
A built-in, high-sensitivity UHF sensor serves as a standard reference, facilitating direct comparison of sensitivity and performance with the equipment under test.
