THERMAL DECOMPOSITION OF SF6 AND SF6-AIR …

With a normal leakage rate of SFß of 1% per year from equipment, the concentration of SFß in the substation air is expected to be well below the TLV. However, during gas filling and venting operations of gas components, there are times when the concentrations of SFß in air in specific loions are much higher than from leakage alone.

Temperature Distribution and Pressure Response of …

Introduction For high-voltage transmissions, gas-insulated switchgear (GIS) is of many merits such as compactness and high reliability. GIS was first used in the latter half of the 1960’s in Japan, since then, it has been highly developed because it answered for the unmanned, digital and smart tendency of transformer substation.
