    Translate this pageSF6 is an electronegative gas with superior insulation characteristics (see section 3.1.2). The gas also has the ability to assist arc quenching, due to its thermal and electronegative properties. The gas is kept in a closed cycle, i.e. not released to the atmosphere. The circuit breakers are usually spring operated.

    Translate this pageCommissioning a substation or medium-voltage switchgear line-up both safely and on schedule requires signifi- cant planning, documentation, and effort, as discussed by Bowen in [1]. Most new switchgear is assembled and tested in the factory. However, some equipment suppliers may claim to test the switchgear but in fact may not truly perform comprehensive testing.

    This, in turn, causes further increase in temperature of the winding. Fortunately, heat is also dissipated (naturally, by forced air, by water, by some gas, etc.) and the rate at which it is dissipated is proportional to td4, where td is the temperature differential (temperature reached – ambient temperature).
