Abstract
An electrical apparatus for a medium- to high-voltage current transport line having a gas insulation including: a sealed housing filled with an electrically insulating gas including at least one fluorinated compound such as a fluoroketone, at least one electrical component arranged inside the inner space of the housing, and a mechanism regulating an amount of the fluorinated compound inside the inner space of the housing. The regulating mechanism includes a heater, heating a liquid resulting from condensation of the fluorinated product present in the insulating gas, to cause at least a portion of the liquid to vaporize.
