Important points for SF6 gas leakage on-site test for high voltage switchgear
SF6 Gas Leakage Testing on SitePurposeSF6 gas leakage testing is conducted to ensure that there are no gas leaks at the field-assembled joints of Gas-Insulated Switchgear (GIS). Leaks can occur during field assembly due to various factors such as damaged sealing surfaces, improper placement, incorrect application of seals, seal damage or omission, improper application of lubricants and sealants, misalignment or inadequate tightening of mating surfaces, and contamination.ScopeExclusions: There is
