  • UHF PD Monitoring for GIS – GE Grid Solutions

    UHF PD Monitoring for GIS. Gas Insulated Substations have become more frequent sites due to their reduced footprint and high reliability of operation. But this reliability can be undermined by the presence of free moving metallic particles originating from breaker operations or mechanical vibrations. These particles can generate high electric fields locally initiating partial discharges (PD) within the insulation.
