Dissolved Gas Analysis Using the Dempster-Shafer Rule of Combination

Dempster-Shafer 결합 규칙을 이용한 유중 가스 분석법

This paper presents a new approach to diagnose and detect faults in oil-filled power transformers based on various dissolved gas analyses. A theoretic fuzzy information model is introduced, An inference scheme which yields the 'most' consistent conclusion proposed. A framework is established that allows various dissolved gas analyses to be combined in a systematic way such as the Dempster-Shafer rule. Good diagnosis accuracy is obtained with the proposed approach.
