变压器零序阻抗的实测与计算

Actual Measurement and Calculation of Zero-sequence Impedance of Transformer

文章阐述了变压器零序电抗的实测方法并给出了折算成标幺值的公式 ,同时分析了常用的变压器零序电抗与正序阻抗之间的关系 ,为简化计算提供了方便。

The paper addresses the actual measurment method in additon to the formula for transformer zero-sequence impedance reduced to standard value. It also analyzes the relation between transformer zero-sequence impedance and transformer positive-sequence impedance, which affords convenience for simplified calculation.
