Partial discharge testers are widely used for partial discharge detection in high-voltage electrical equipment such as transformers, GIS (gas-insulated switchgear), high-voltage switchgear, cables (and terminals), motors (especially drive motors for new energy vehicles), instrument transformers, bushings, surge arresters, and capacitors. Application scenarios cover equipment type testing, factory testing, R&D testing, on-site inspection, live-line testing, and online monitoring. They are used in power equipment manufacturers, power generation and supply operation departments, power construction, installation, and commissioning departments, and research institutions.
Power Equipment Manufacturing: Type testing, factory testing, and new product development testing of high-voltage electrical equipment such as transformers, instrument transformers, cables, bushings, capacitors, surge arresters, GIS, and switches, ensuring insulation quality meets the requirements of standards such as IEC 60270 and GB/T 7354.
Power System Operation and Maintenance: Live-line inspections, handover tests, and periodic inspections in substations, distribution rooms, and other locations to promptly detect insulation deterioration, installation defects, or latent faults, supporting the transition from "periodic maintenance" to "condition-based maintenance."
Scientific Research and University Experiments: Used for research on insulation material properties, discharge mechanisms, verification of new detection technologies, and insulation design evaluation of high-voltage equipment.
