变压器纵差保护调试方法解析

Analysis of Transformer Vertical Differential Protection Test Method

阐述了国内不同变压器保护装置厂家主流变压器纵差保护的折算原理,根据不同厂家采用的折算过程,对各种变压器纵差保护的三相平衡、单相平衡、定值校核试验方法进行了详细解析,建议工程调试人员应根据各生产厂家的纵差保护折算原理采取不同的方法进行校验,避免得出错误的试验结论。

Based upon calculating principle of transformer vertical differential protection from individual manufacturer’s product, test method of three-phrase balance,single-phrase balance and settings verification are analyzed in detail in this thesis. Conclusions are presented that different test methods should be adapted to different calculating principle.
