| Abstract: | This paper discussed the effectiveness of preventive tests for large power transformer, such as insulation resistance and DC resistance measureme'nt,dielectric loss factor,oil-paper insulation dissolved gas analysis, water content in oil and so on. Some advisements, such as detect method, fault diagnosis, and development of condition-based maintenance of power transformer are put forward in this paper. |
