Partial Discharge Measurement (GIS)

Partial discharge measurement is one of the most important tools for GIS insulation condition assessment. Partial discharge (PD) in gas insulated switchgear is a leading indicator that a fault is going to occur and immediate action needs to be taken. A GIS failure would be a calamity. PD in GIS can be caused by particles floating in the gas insulation, or loose or broken components such as a piece of metal shaving that gets too close to a conductor. PD can occur in solid, gas or liquid medium and PD voltages vary depending on the insulation material.

UHF 800

Our portable, easy-to-use UHF 800 system performs sensitive offline and online partial discharge (PD) measurement and analysis in the ultra-high frequency (UHF) range from 100 to 2000 MHz on gas-insulated switchgear (GIS) and gas-insulated lines (GIL). This ultra-high frequency partial discharge testing system is used for insulation condition assessment and insulation defect detection in noisy testing environments – especially during on-site commissioning (acceptance testing) and troubleshooting.
