I dont know much about high voltage breakers, but can tell you that if your breaker is low on SF6, it probably has a leak. Most leaks allow atmospheric gas to enter while the contained gas leaks out.Leak Testing, Transformer Tanks, Assemblies: 695 MVA2014-9-29How to Calculate the Short Circuit kA Level of 132kv/34.5kV 30MVA T…2014-7-8low pressure drain and high pressure vent line2009-1-3Power Supply for Advantest R4131A2008-1-7See more results
