摘要
Y/△变压器差动保护调试过程中,由于人员对其原理理解存在偏差,变斜率差动曲线的验证往往成为难点。分析了其保护原理并总结其采用的电流补偿方法。以Y/△变压器为例介绍了校验步骤,提出了验证差动曲线的方法。
There is a deviated understanding of the principles in the debugging process of Y/△ transformer differential protection,so the validation of the variable slope differential curve often becomes difficult.Aanalyzes the principle of the protection and summarizes the current compensation method.Introduces verification steps with Y/△ transformer as an example,and puts forward methods to verify the differential curve.
