Product Description

Product Description

PARTIAL DISCHARGE DETECTOR EQUIPMENT

Partial discharge detector is suitable for the online partial discharge measurementof electrical apparatus, such as surge arresters, insulators, power transformers,generators, CT/VT, GIS, capacitors, power cables and switchgears. 

Specification

Applications

1.Accurate Partial Discharge Detection:Real-time captures partial discharge signals inside power equipment (e.g., transformers, switchgears, cables, instrument transformers), precisely locating the discharge position and intensity.
2.Early Warning for Insulation Hazards:Judges potential issues like insulation aging or damage through test data, issuing early warnings before serious failures (such as short circuits or breakdowns) occur.
3.Ensure System Safe Operation:Prevents power outages caused by insulation failure, reduces operation and maintenance costs as well as safety risks, and extends the service life of power equipment.
4.Multi-scenario Adaptation:Supports offline on-site testing, online real-time monitoring, factory quality inspection and other scenarios, meeting the needs of power engineering, industrial production, etc.
