| Abstract: | The static volt-ampere characteristics of arc and the arc stability influenced by the resistance, voltage and volt-ampere characteristics of the power source was analyzed through establishing the static model of arc fault in order to detect arc fault effectively and provide certain theoretical basis for arc fault detection technology. It was analyzed too that the dynamic characteristics of arc fault based on power frequency and phase characteristic of arc fault line cur- rent and voltage under power frequency half cycle. The above analysis showed that volt-ampere characteristics of arc is closely related to the factors such as the arc current value, electrode materials, arc length and arc around the cooling degree, gas composition, and the current frequency. |
