GIS or Gas Insulated Switchgears utilizes SF₆ as the insulating medium. Hence, it extremely important to ensure that there is no gas leakage and the SF₆ gas quality is in good condition.
At CST, we have the equipment and necessary expertise to detect gas leakage as well as testing the quality of SF₆ gas.
Parameters measured include, which includes Dew Point, SO₂ content and SF₆ purity, are compared with IEEE guideline to determine the quality of the gas.
All gas extracted for the analysis will be pumped back to the GIS, there are no concerns of gas depletion in the GIS and environmental pollution.
