SF6 Breakers maintenance systems manufacturer

Oct 19, 2006SF6 breakers are relitively maintenace free, however that does not mean maintenance should be ignored. As a formed service rep for a HV breaker manufacturer, I can assure you that megger or doble type tests will fail to yield any significant results (other than good) for an SF6 breaker.

  • SF6 circuit breaker maintenance | TD Guardian Articles | USA

    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.
