The application analysis of the on-line monitoring system of dissolved gas in transformer oil

Technology of on-line monitoring of dissolved gas in transformer oil is the focus of attention nowadays. As the technologies of computer, macromolecule materials and optical spectrum analysis develop rapidly, the on-line monitoring devices are more and more perfect and are used more popular in electric power production. In this paper, the on-line monitoring device of dissolved gas in transformer oil typed HYDRAN20li is set as an example and the working principle and the properties of this kind of systems are introduced. Some common problems in using on-line monitoring devices are brought up and the settlement methods are described. This paper gives consultation to the maintaining of the on-line monitoring devices.
