Dissolved gas analysis using expert system

This project is to study a dissolved gas analysis of transformer oil using an expert system. A prototype of an expert system based on the dissolved gas analysis techniques for diagnosis of a suspected transformer faults and the appropriate maintenance actions to be taken. This method is proposed to assist the conventional gas ratio method based on the International Electrotechnical Commission (IEC), Central Electric Board (CEGB) and California State University-Sacramento (CSUS) standards and guidelines. A software program called Exsys Corvid has been used in the decision making. Exsys Corvid is a new and revolutionary approach in developing and fielding online advisory systems that provide the much needed requirements. An expert system can be used as an alternative to the conventional methods where no is calculation is needed. It also gives the user information pertaining to transformer operating conditions and the recommended actions should be carried out before any failures to occur.
