Study on the characteristics of hybrid ionized field under different transmission line structures

In order to study the complex electromagnetic environment under the AC and DC parallel transmission lines, the hybrid ionized field characteristics under different line structures are studied. The influence of DC line pole spacing, AC and DC parallel spacing, AC line voltage level and other factors on the hybrid ionized field are considered. The results show that the influence of the DC line polar distance on the hybrid ionized field is negligible, and the change of the AC and DC parallel spacing in different ranges has different effects on the hybrid ionized field, and with the increase of the AC line voltage level, it will reduce the hybrid ionized field under the line.
