In the paper, the reduced single phase short-circuit current equation expressing as positivesequence impi dance only is showed.
文中还提出了低压系统中只用正序阻抗表达的单相短路电流的简化计算公式。

The three phase detecting method closely connects with the Park transform and the result is the positivesequence part of the fundamental frequency.
三相求法与派克变换有很密切的联系，求出的是三相基波正序分量。
