  • Fill Up or Top-up 132kV With SF6 Gas - CR4 Discussion Thread

    Jan 28, 2013I 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. This means that if you refill the breaker with SF6, the contaminating gasses will still be present in substantial quantities.Leak Testing, Transformer Tanks, Assemblies: 695 MVASep 28, 2014Opening of 132kV Breaker with Very Low SF6 PressureFeb 14, 2012low pressure drain and high pressure vent lineJan 02, 2009Power Supply for Advantest R4131AJan 06, 2008See more results

    The first generation of SF6 circuit breakers was the lower voltage classes of 72kV and 145kV. As SF6 breaker technology improved, circuit breaker manufacturers introduced a dual pressure design for 145kV through 800kV applications, as well as air-blast breakers utilizing SF6 as the line-to ground dielectric insulation.
