Portable GIS Partial Discharge Detector

Model: JHPD-20

JHPD-20 detects and diagnoses the partial discharge inside the gas insulated switchgear (GIS). By using the UHF sensor attached on the surface of GIS or inside the GIS and the noise sensor which excludes the disturbance signal, the detector analyzes the GIS operation condition.

  Features
 
---  Light weight: easy for on site operation.
---  User friendly interface and simple operation design.
---  Outside and inside sensor are acceptable to monitor the partial discharge inside the GIS.
---  Acoustic sensor distinguishes the ambient noise and improves the reliable of the PD signal recognition.
