SF6 End-of-life Analysis for 132kv

SF6 End-of-life Analysis for 132kv

The transformer is YN-auto-connected with an on-load tap changer in the neutral. The low voltage terminal can be connected to one of several tappings in off-circuit condition. In this way the following voltage ratios are achieved: 400kV to 230kV, 400kV to 132kV, 400kV to 110kV, 230kV to 132kV and 230kV to 107kV.

  • SF6 circuit breaker maintenance | TD Guardian Articles

    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.
