Since the second industrial revolution, electric energy has always been the most important and indispensable clean energy in the international community. As a kind of transmission technology with small loss ratio and long transmission distance, UHV transmission is widely used and vigorously promoted in the world. However, UHV transmission lines are often assumed to be vulnerable to thunderstorm discharge in some harsh geographical environment. In order to improve the calculation accuracy of line shielding failure rate, an improved electrical geometric model is proposed to study the shielding failure characteristics of transmission lines under complex mountainous areas, and various typical characteristics including mountain tops, valleys, slopes, climbing, and crossing trenches are summarized.
