With the implements of China's Western Development Project and West-East Power Transmission Project, transmission lines will inevitably pass through high altitude regions with complex atmospheric conditions. Air density and air humidity along the line passages will change much, which will affect the corona discharge performance of conductors. Studies about the effect of air density and air humidity...
Switching impulse discharge performance of air gaps at high altitudes, which is a fundamental in the extremely high voltage external insulation design, remains an unsolved key technology across the world. Due to the limited applicable range of "g" parameter method recommended by IEC Publication 60-1(1989), this paper aims to explore the relationship between positive switching impulse 50%...
