Abstract

Transformer DC resistance test is one of the routine test in the transformer core project, but the test efficiency is generally low.The paper ,through the analysis of transient process of large DC resistance measurement of transformer coil, core hysteresis phenomenon and the influence of residual magnetism on the measurement process.Improve the working principle, a method of fast measurement, large transformer DC resistance does not increase ,in other devices,characteristics of combination of YNd11 connection of three-phase transformer testing instrument and physical characteristics of the proposes. Field test proves that this method effectively utilizes the remanence, can get the main transformer winding DC resistance test results quickly and accurately.
