  • Analysis of the breakdown fault in field voltage withstand

    So this paper suggests that the production process of SF6 current transformer should be monitored. And after it has been installed, we have to do the aging test and voltage withstand test. To prevent the same fault of 500kv current transformer occurs again, the results in this paper can give some reference and engineering application consult.

  • SF6 Circuit Breakers - TestGuy

    SF6 has a tendency to liquefy and pool at colder temperatures. This reduces the internal pressure, which reduces the dielectric strength. Dead Tanks vs. Live Tanks. Dead tank breakers have grounded tanks. Live tank breakers use the insulating column to house the mechanism and contact assemblies, so they are energized at system voltage (live).
