GIS Partial Discharge Fault Simulation Test Setup

MOEORW-W5080U equipment is specially developed for scientific research on 110kV~500kV GIS detection, calibration of power detection instruments, power laboratory teaching in universities, and performance evaluation of testing equipment for power grid operation and maintenance units, serving as an industry-standard test platform for simulating all types of GIS partial discharge defects.
1.It can fully reproduce four typical single and composite insulation defects occurring in field GIS equipment: tip discharge, floating potential discharge, metal particle surface discharge, and air gap discharge inside insulators. Two independent simulation chambers for basin insulator defects and SF6 gas humidity deterioration are additionally equipped, covering over 95% of all GIS faults encountered on site.
2.Compatible with five mainstream live detection technologies: pulse current method, UHF ultra-high frequency method, AE ultrasonic method, HF high-frequency method, and SF6 gas composition analysis. It provides an all-in-one solution for R&D, factory calibration of testing equipment, and practical training for field operators.
3.Equipped with an integrated infrared visual monitoring module to capture micro discharge processes in real time and generate standardized partial discharge PRPD and phase patterns, supplying standard test samples for AI partial discharge pattern recognition databases.

Different from simple single-defect simulation devices available on the market, this equipment integrates authenticity, integrated structure, controllable discharge, multi-detection compatibility, metrological traceability, stable reusability, easy operation, visual monitoring, built-in sensors and mobility. Every feature is supported by hardware structure and quantified technical parameters without exaggerated marking.

1.High Simulation Authenticity: Fully replicates the tank structure, compartment separation and basin insulator installation form of real 110kV GIS equipment. The internal electric field distribution and insulation structure are consistent with on-site GIS, enabling test data to directly reflect actual operating conditions. The partial discharge level of the main body ≤1pC (the highest no-partial-discharge grade specified by national standards), so the inherent base discharge will not interfere with defect test results.

2.Integrated All-in-One Design: No external separate high-voltage power supply. The 5kVA no-partial-discharge test transformer and 50pF coupling capacitor are fully built into the GIS tank to eliminate interference from external high-voltage wiring. The whole unit supports single power supply with multiple reserved power interfaces for external testing equipment. Compared with split-type devices, it reduces floor space by 40% and wiring workload by 60%.

3.Full-Range Fault Simulation: Four basic defect modules can be triggered individually or simultaneously, matched with independent insulator fault chamber and humidity simulation chamber. Supports replacement of basin insulators of any manufacturer and specification for comparative tests. External screw rods adjust defect distance to precisely control discharge inception voltage, extinction voltage and partial discharge amplitude, with reproducible defect signals.

4.Temperature & Humidity Condition Simulation: Equipped with closed-loop temperature rise system and distributed temperature sensors, it can simulate GIS operating environments from -25℃ to 50℃, quantifying the impact of temperature on partial discharge signal amplitude and phase characteristics, suitable for scientific research on extreme working conditions.

5.Multi-Method Detection Compatibility Platform: Simultaneously supports five detection technologies including pulse current, UHF, ultrasonic, high frequency and SF6 gas analysis. One single unit can complete factory calibration for various partial discharge detectors, cutting customers' procurement costs for multiple testing devices.

6.Metrological Traceability Function: Built-in standard pulse coupling calibration rod with internal calibration reference, serving as a metrological transfer standard source. Test data generated has metrological credibility, meeting the instrument calibration business demands of third-party testing institutions.

7.Long-Term Stable Reusability: Discharge defect modules adopt special alloy insulation structure with designed service life over 5 years. The whole tank and sealing system can serve more than 20 years. Discharge characteristics show no obvious deviation after thousands of repeated discharge tests, eliminating frequent replacement of spare parts and greatly reducing customers' later maintenance costs.

8.Convenient External Control: All knobs for defect start/stop and intensity adjustment, gas charge/discharge valves and temperature control panels are arranged on the exterior of the unit. Test parameters can be adjusted without opening gas chambers, and one single operator can finish the whole test process.

9.Compatibility with Multiple Types of Basin Insulators: Supports quick disassembly and assembly of three mainstream insulator types: fully shielded, bare and casting port insulators, compatible with mainstream 110kV GIS matching insulators on the market. Customers can conduct customized fault tests with self-owned insulators.

10.Infrared Visual Monitoring: 4 built-in 480P infrared cameras capture internal discharge flashes in real time. Remote real-time viewing is available on Windows PCs, Android and iOS mobile terminals, with synchronous recording of discharge videos to preserve original test materials.

11.Integrated Built-In Sensors: UHF receiving antennas (detection sensitivity: 0.5pC) are pre-installed inside the tank, with standard signal output ports reserved externally. No extra external sensors are required, avoiding signal attenuation errors caused by external installation.

12.Mobile Base Structure: Equipped with silent load-bearing universal casters, the whole unit can be moved and transported by one person, enabling flexible switching between labs and test sites without hoisting equipment.

13.Sealing & Gas Safety: Annual gas leakage rate of single SF6 compartment ≤0.3%, no leakage alarm during 24-hour wrapping leak detection, stable gas pressure maintained within the standard test range of 0.45~0.6MPa. No frequent gas refilling is required for long-term tests, lowering SF6 consumable costs.

All parameters are verified through actual testing in third-party high-voltage laboratories. Each unit is delivered with a parameter calibration inspection report without vague marking, which can be directly cited for bidding and laboratory qualification applications.
