3) external fault
外部故障
1.
Analysis of the maloperation of transformer differential protection after external fault removed;
变压器外部故障切除后差动保护误动原因的分析
2.
Based on this, the paper presents a new transformer protection criterion to distinguish internal faults and external faults by correlation coefficients of sampled current values.
在此基础上,提出一种基于电流采样值相关度的变压器保护新判据,利用变压器两侧电流采样值波形的相关度来区分内部故障和外部故障。
3.
Mal-operation of the transformer differential protection will occasionally take place after the removal of the external fault.
针对近年来相继出现的变压器差动保护在外部故障切除后发生误动的现象,研究了电流互感器(current transformer,CT)饱和以及Y/Δ接线变压器补偿方式对差动保护的影响。
4) outside faults
