Abstract In response to issues such as the diverse waveforms of arc high impedance faults in distribution networks, significant discrepancies between simulated and actual waveforms, which resulting difficulty in generalizing existing fault recognition models, the voltage-current characteristics of existing simulation models are analyzed firstly in this paper. Then experimental data are obtained to examine the actual voltage-current characteristics, and the differences between simulation and measured waveforms are analyzed. Finally, the characteristics influencing waveforms, including nonlinearity, stochasticity, intermittency, thermal inertia, and “shoulder” offset, are summarized, and improvement suggestions are proposed based on the consideration of reactive components.

Key words： distribution network arc high impedance fault simulation model difference voltage- current characteristic
