摘　　要：通过实例分析,提出了变压器出厂前、运输后和短路电流冲击后,用低电压电抗法检测电力变压器绕组和铁芯的动稳定状态参数的方法,并对几种方法进行了比较,分别指出了其作用和意义。Based on an example, before transformer leaves the factory, after transportation and short-circuit current, using low voltage reactance law to check the electric power transformer winding and the iron core＇s dynamic stability state parameter method is suggested. Comparison on several kinds method has given, and has pointed out whose effect and significance respectively.
