IS-PDS-GI255M

Insulation defects occur due to electrical/mechanical stress and other environmental factors, with the occurrence patterns of partial discharge varying depending on the type of defect. In the case of Gas Insulated Switchgear (GIS), defects such as conductor and outer casing protrusions and spacer cracks may arise during manufacturing, transportation, installation, and operation. IS-PDS-GI255M measures partial discharge signals in the UHF (Ultra High Frequency) band caused by internal GIS defects, enabling early detection of GIS faults and supporting reliable equipment operation.
