Moisture is continuously monitored in the vacuum evacuation and gas refill of oil-filled transformers. The moisture content of blanketing gases used in the transformers directly affects the dielectric properties of the oil, through water vapour dissolution.

One of the most widespread liquid electrical insulating materials is transformer oil. It is used to fill the pores in the fiber insulation and the space between the windings, thereby increasing the dielectric strength of the insulation and improving the heat removal from the windings and the core of a transformer.
