Gas insulated switchgears (GIS) are part of T&D facilities. The most serious issue for GIS inside inspection is that we need long time power outage, when withdrawing SF6 gas from GIS tanks and restoring it after the inspection. Therefore, we propose X-ray diagnosis service that can check the soundness of GIS without any power outage and opening GIS tanks.
The X-ray diagnosis checks inside of circuit breaker such as the moving parts, the fixed parts, wear and tear of arcing contact, fastening bolts and other components of GIS without power outage and without withdrawing SF6 gas. *
Images captured at the inspection are shade-corrected in a phased manner to collect clear and detailed data.
X-ray diagnosis can be performed without opening GIS tank, which means you do not need SF6 gas handling. It leads to cut inspection time and cost significantly.
You can detect loosened screws and inadequate insertion dimensions of the main contactor to prevent serious accidents quickly and easily. Furthermore, X-ray diagnosis does not require to work inside of tank. Therefore, you can prevent any kind of accidents and human errors concerning inspection job.
