ABSTRACT:
The removal of undesirable substances such as water, PCB's and air from the internal components of electrical devices such as transformers and power capacitors is efficiently and effectively achieved by contacting, in the absence of air, the internal components of these various electrical devices with a heat-stable fluid material. The heat-stable fluid materials are preferably halogenated aliphatic hydrocarbons and most preferably perchloroethylene or FREON 113.
