  • Based on the equivalent circuit of V/X wiring traction transformer, a calculation model of short-circuit reactance was established to effectively detect the transformer winding deformation by using the monitoring current and voltage data of each primary phase and the feeder line. According to the relative standard deviation of monitoring data, the precision control method for test results was presented. The results show that even without additional sensor installed on the windings, the tested short-circuit reactances of A-B phase and C-B phase of a V/X wiring traction transformer with the proposed method are 67.31 and 61.18 Ω, respectively, which are very close to the off-line test data of 67.40 and 61.27 Ω, revealing that the proposed on-line monitoring method is effective and practical.
