摘　　要：采用单相接地故障相经低励磁阻抗变压器接地方式,在对单相接地故障实施保护的同时,通过低励磁阻抗变压器注入信号实现单相接地故障的定位与隔离,经现场试验,验证了理论分析的正确性。The single-phase grounding fault phase is grounded through the low excitation impedance transformer.While protecting the single-phase grounding fault,the single-phase grounding fault location and isolation are realized through the injection signal of the low excitation impedance transformer.The correctness of the theoretical analysis is verified by the field test.

关 键 词：低励磁阻抗变压器 信号注入
