The analysis of secondary arc spectrum characteristics on UHV transmission lines


On ultra-high-voltage (UHV) lines, the existence of secondary arc impact on the stable operation of system, so it is necessary to further study secondary arc. The paper adopts total harmonic distortion (THD) to judge the status of arc. First, the simulation model of secondary arc is established by ATP software. Then, faulted phase voltage and secondary arc… (More)
