Abstract  Against the lack of transient characteristic analysis conclusion of single-phase ground fault in resonance grounding system, the influence of fault initial phase and ground resistance was researched from time domain, the phase-frequency characteristic of equivalent impedance of various structural lines was analyzed detailed from frequency domain, the distribution rule of transient zero-sequence capacitive current in different structure of transmission lines was revealed, the SFB of resonance ground system was determined. The correctness of conclusion was verified by large of simulation experiment.
Key wordsresonance grounding system      single-phase ground fault      time-domain characteristic      phase-frequency characteristic      selected frequency band
