Improving a tower earthing system by reducing the impedance is an effective solution to prevent back flashover from occurring and thus maintaining sustainable operation of power supply. Knowledge soil structure important element when designing determine parameters transmission line (TL). This paper presents computation interpretation based on several designs using current distribution, electrom...

Traditionally in workshops conflicts arise between requirements for the safety of human beings and requirements to prevent stray currents. Within workshops more strict limits for step and touch voltages apply than for the rest of the railway system. These requirements can be met in case the running rails are connected to ground, but this will increase stray currents. As The Netherlands is a ver...

In the usual practice, evaluation of overvoltages due to direct lightning strikes overhead power lines is focused on representation effects current injection, whilst coupling between conductors and electromagnetic pulse (LEMP) disregarded. Motivated by recent results obtained for case a medium voltage line configuration with shield wire, this paper extends analysis assess contribution LEMP perf...
