The power and electrical industry prioritizes insulation safety to prevent short circuits and electric shocks, and the Withstand Voltage Tester is a critical tool for this. It detects insulation weaknesses, solving hidden safety hazards in equipment and systems.
Power Transformer Testing: Ensuring Insulation Reliability
Firstly, power transformers are core components of grids, and their insulation performance directly affects system stability. The Withstand Voltage Tester applies AC/DC high voltage to transformer windings, checking for insulation breakdown.
Moreover, it supports variable voltage output (up to 100kV) to match different transformer ratings. This solution identifies insulation aging or defects early, avoiding transformer burnout and costly grid outages.
Electrical Equipment Manufacturing: Compliance with Safety Standards
Manufacturers of motors, switchgear, and cables must meet IEC 60664 and GB 14711 insulation standards. The Withstand Voltage Tester conducts routine withstand voltage tests during production, ensuring products meet market access requirements.
นอกจากนี้, it has built-in arc detection to avoid damaging good products during testing. This solves the problem of over-testing or under-testing, balancing product quality and production efficiency.
Power Distribution Network: Preventing Line Faults
Secondly, power distribution lines and switch cabinets face insulation degradation due to humidity, dust, and aging. The Withstand Voltage Tester performs on-site tests to evaluate insulation condition.
Furthermore, its portable design allows testing in remote areas or high-altitude power stations. This solution helps maintenance teams replace faulty components in advance, reducing line tripping rates by 35%.
Renewable Energy Systems: Testing PV & Wind Power Equipment
PV modules and wind turbine converters operate in harsh outdoor environments, requiring robust insulation. The Withstand Voltage Tester checks the insulation of PV strings and wind power inverters, ensuring safe operation.
For example, it tests the withstand voltage of PV module junction boxes to prevent leakage current. This solution extends the service life of renewable energy equipment and reduces maintenance costs.
Electrical Maintenance & Overhaul: Post-Repair Validation
ในที่สุด, after repairing electrical equipment (เช่น, motors, transformers), maintenance teams use the Withstand Voltage Tester to verify insulation recovery. This ensures the equipment is safe to put back into service.
Its data logging function records test results for traceability, meeting the documentation requirements of industrial safety audits. This solution eliminates potential safety risks from incomplete repairs.
Core Value: Safety & Compliance Driven by Precision Testing
The Withstand Voltage Tester combines high voltage accuracy (±1% of full scale) with user-friendly operation. It is available in bench-top and portable models, adapting to different testing scenarios.
In the power and electrical industry, it’s not just a tester—it’s a solution that safeguards personnel safety, ensures system stability, and helps enterprises comply with strict insulation standards.
