Fault localization on transformer winding by frequency response analysis and evidential reasoning

Fault localization on transformer winding by frequency response analysis and evidential reasoning

In this paper, a novel fault localization method combining frequency response analysis (FRA) and evidential reasoning process is proposed. FRA test is conducted at first so that we can obtain corresponding responses of several monitoring nodes on the winding. Traditional FRA interpretation methods s...
