Partial Discharge Sensor for GIS

  • 원준 이 
Partial discharge diagnosis within GIS can be measured by installing an external installed UHF sensor and estimating the location of partial discharge occurring. In addition, partial discharge data are measured for real-time monitoring of partial discharge conditions occurring during GIS operation and data necessary for diagnosis of GIS insulation abnormal conditions are provided.

Partial Discharge Sensor for Transformer

  • 원준 이 
In the inlet transformer where insulators including insulating oil, insulating paper, and press board are used, poor manufacturing of insulating materials or deterioration of age may result in initial partial discharge due to weakening of insulation strength, and depending on the time of use, such partial discharge will further weaken the insulation resistance, leading to unforeseen major accidents.
