Case Analysing and Fault Judgment in Measuring Transformer DC Resistance
Zhang Jian-xue · Journal of Electric Power · 2010
This paper described some factors that affect the accuracy of transformer DC resistance measurement.Then it preliminarily judges the specific reasons of unbalanced three-phase rate exceeding through living examples.And it takes some necessary measures.Furthermore Using another method to determine the correctness of the preliminary judgment,it provides the foundation of the correct data for accurate judgment of transformer fault location and fault type.
