摘要
变压器纵差保护的差动回路中出现的不平衡电流越大,保护的灵敏度也就越低。因此重点分析变压器纵差保护不平衡电流产生的原因,并寻求减少它对变压器纵差保护影响的主要措施。
The more unbalance current appears in the transformer longitudinal differential protection differential circuit,the less sensitivity it has. The cause of its creating unbalanced current was emphasized to analyze. The main measures for reducing the impact on this protection were sought.
