摘要
实际运行中 ,变压器差动保护可能在非故障的情况下发生误动。文章认为二次回路阻抗偏大及存在大功率谐波源是产生这一现象的主要原因 ,并介绍了处理方法。
In practical running, the differential protection of transformer may happen to be tripped in non fault. The article holds the primary reasons for this phenomenon are secondary circuit arise to high-impedance and there is the high power harmonic source,the article also introduces some ways to avoid them.
