sf6 insulated switchgear Analysis for Transformers

Since gas insulated switchgear (GIS) is filled with SF6 gas as insulation, partial discharge can be caused by floating particles, loose or broken components such as a piece of metal shaving that gets too close to a conductor. Partial discharge can occur in different type of medium whether it be in a solid, gas or liquid.

  • SF6 Insulated Current Transformers – Trench Group

    SF 6 insulated current transformer are used to convert high transmission line currents (up to 6000 A) to standardized low and easily measurable values, which will be used for metering, protection and control of the high voltage system. As such, the need for accurate and reliable current transformation is essential. The reliability and security of Trench gas-insulated instrument transformers
