| Abstract: | In this paper, the concept of equivalent sounad velocity is defined and its stability is discussed. Based on the stability of equivalent sound velocity, three mathematical models for the location of partial discharge source in a power transformer are constructed and an algorithm by using optimization method is developped.The algorithm has been proved to be effective in practical locating examples. |
