| Abstract: | According to the information on transformer faults provided by major electric power companies in China from 1990 to 1998, the statistics and analysis on the transformer damages caused by short circuit faults in 110kV and higher voltage classes are carried out. The general situation of high capacity power transformer damage caused by short circuit is summarized, the feature and regular patterns of these faults are put forward. The result of analysis can be used as a good guidance of improving power transformer secure operation and provides an objective foundation for the manufacturers of high capacity anti break down transformers in China. |
