摘要
根据自耦变压器的特性，分析了自耦变压器发生区内、区外接地故障时的故障电流，讨论了３种形式的自耦变压器零序差动保护的优、缺点，并提出改进建议。
According to the characteristics of autotransformer, the fault current of autotransformer is analyzed when the ground fault happens in and outside of the protected zone. The advantages and disadvantages of three kinds of zero-sequence current differential protections of autotransformer are discussed and some suggestions are given . This paper has something important to improve the application and sensitivity of zero-sequence current differential protection of autotransformer.
