Partial Discharge Sensor for Transformer
ISAAC-PDS-MH165
| Product Overview |
| 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. Depending on the time of use, such partial discharge will further weaken the insulation resistance, leading to unforeseen major accidents.
The UHF PD measuring sensor (ISAAC-PDS-MH165) is a transformer manhole mounted sensor that measures partial discharge within the transformer by connecting to a system that pre-detects insulation deterioration of the transformer. The above equipment detects signals in the UHF band and improves measurement sensitivity and is good for reducing external noise. |
