摘要

A novel strategy for monitoring the state of power transformer windings by on-line measurement of short-circuit reactance is studied on a model transformer in lab condition. The results and their comparisons with those obtained in out-of-service condition show that the on-line method is able to detect short-circuit reactance variations with high degree of accuracy, precision and good stability, and therefore can be used for diagnosis of deformation in the transformer windings. The changes of the operation condition of transformer and the external factors, such as the field interference, do not exert an effective influence to the results.
