Overview
Partial discharge detection of GIS equipment serves as a core method for condition-based maintenance of power equipment. In field operations, it is difficult to stably obtain typical faults such as tip discharge, floating discharge, particle discharge and surface discharge. Field fault tests carry high risks and are non-reproducible, which creates major challenges for technician training and partial discharge instrument calibration.
MOEORW-WPi80 GIS Partial Discharge Defect Simulation Device adopts an SF6 gas-filled sealed cavity. It can stably reproduce four typical types of GIS partial discharge defects, providing safe and controllable partial discharge test conditions for state grid enterprises, equipment manufacturers and research institutions.
01 Core Product Highlights
✅ Integrated with four typical defects. The SF6 gas chamber embeds four discharge simulation modules: tip, floating, particle and surface discharge. The defect signatures are close to real GIS faults, enabling repeatable simulation tests.
✅ Ultra-low background partial discharge interference. Background partial discharge ≤2 pC under rated voltage; system noise ≤45 dB. Waveforms are clean and distinct, preventing background noise from interfering with defect identification.
✅ Manual / automatic dual control modes. Matched with an automatic operation console integrated with an isolation transformer to suppress external electromagnetic interference. Simple voltage boosting operation, suitable for teaching demonstrations and batch comparison tests.
✅ Multiple signal output interfaces. Equipped with partial discharge sampling ports and ultra-high frequency (UHF) interfaces. Compatible with pulse current, UHF and multiple partial discharge detection instruments for equipment calibration and spectrum collection & comparison.
✅ Complete high-voltage safety protection. Overvoltage and overcurrent protection included. Continuous operation for up to 30 minutes under rated working conditions to support stable training and research tests. Fitted with casters for easy on-site relocation.
