Analysis of the electrical characteristics and surge protection of EHV transmission lines supported by tall towers

•Electric parameters of the 280-m-tall transmission line were analyzed.•Frequency-domain analysis of the longitudinal parameters.•Time-domain analysis of the electromagnetic transients and possible overvoltages.•Proposal of an alternative lightning protection using ZnO line surge arresters.•Major su...
