ABSTRACT:
An apparatus for monitoring gas dissolved in an electrically insulating oil used in an electrical apparatus comprises a sampling device connected to a tank for sampling a portion of the insulating oil from the electrical apparatus, an extracting device connected to the sampling device for extracting a volume of dissolved gas from the portion of the insulating oil in the sampling device, and a measuring device connected to the extracting device for measuring the components of the dissolved gas. All of the volume of dissolved gas is delivered from the extracting device either by pumping the oil from the tank to the extracting device to force the dissolved gas to the measuring device or by using a plate of the extracting device to force the dissolved gas therefrom. All of the volume of dissolved gas measured is exhausted from the measuring device. The portion of the insulating oil remaining in the extracting device is returned to the tank.
