This paper presents a new method to locate partial discharge source of transformer single-winding with the transformer single-winding model and Matlab software simulation. This transformer single-winding model is composed of 300m long wire, which is equivalent to the parameter model composed of only capacitors and inductors through the frequency characteristic analysis of transformer winding. In the process of simulation, the bushing and neutral point current of transformer winding are measured when partial discharge occurs in different position. Then we can get position factor related to the current mean and variance measured through calculation, analysis and deduction. Accordingly the position of partial discharge can be found by corresponding relation. This simulation indicates that this method is effective and practical.
