One of the methods that can be applied to improve the lightning performance of overhead power distribution lines is the use of shield wires. Although the effectiveness of this measure against direct strokes is quite limited unless the shield wire is grounded at every pole, the ground resistances are low, and the line has sufficient CFO between the ground lead and the phase conductors, the line performance...
The mechanisms from which lightning overvoltages can be produced on a power line depend on the system voltage. In medium voltage (MV) overhead distribution systems, lightning transients can be originated by either direct or indirect strokes. The main methods that can be adopted to improve the line lightning performance concern the increase of the critical flashover voltage (CFO) of the line structures,...
