Ultimate capacity analysis of transmission tower line system under wind load

open access: yesIOP Conference Series: Earth and Environmental Science, 2021
Abstract As an important part of the large complex lifeline system, the transmission tower line system has many accidents. Based on the static and dynamic calculation theory, the response of the structure is analyzed, the ultimate capacity of the transmission tower system is obtained, and the weak position is studied, and the ultimate ...

Application of the insulator coordination gap models and effect of line design to backflashover studies [PDF]

open access: yes, 2010
Any insulation coordination study must accurately (or as accurately as possible) express the type and magnitude of all overvoltages on the power system. If these overvoltages are higher than the rating of the equipment, they will result in damage to that
