The transmission line is a vital infrastructure in an electrical system, used for transferring electrical energy from power plants to consumers. The main networks of transmission lines, such as conductors and ground wires, are supported by steel lattice towers, and the entire energy system will be disrupted if the tower collapses.

Recently, many transmission towers have collapsed under extreme loading conditions, such as strong winds, earthquakes, rain, ice storms, and cable rupture, causing serious power outages. The shock of earthquake or cable rupture has a great effect on the vibration amplitude of the transmission tower. Therefore, it is essential to propose effective methods to obtain the vibration characteristics and strength capacity of a transmission tower, revealing its failure mechanism. Many scholars have made some pioneering works, and however, there still exist some critical issues, such as the shock theory of extreme loadings, mechanical model of joint effect, the coupling vibration of tower and line, etc.

The Special Issue calls for high-quality unpublished original research and reviews which aim to cover ongoing, emerging developments in the vibration analysis of electrical systems.

Potential topics include but are not limited to the following:

• Shock effects of transmission tower subjected to cable breakage
• Wind-induced vibration analysis of transmission lines
• Calculation model of extreme loads
• Distribution characteristics of extreme climates
• Seismic vibration of transmission lines
• Accurate simulation of tower capacity
• New vibration control technologies
• Fragility analysis of transmission line
• Sensitivity analysis of influencing parameters
• Coupling vibration effect of tower and line
• Failure mechanism of transmission tower
