1. Sensitivity analysis of secondary arc current for different transmission lines / Analise de sensibilidade da corrente de arco secundario para diferentes linhas de transmissão
The secondary arc appears in single-phase switching during clearing of non-permanent ground single-phase to ground faults. The problem happens especially on EHV lines, on aerial isolation, in faults with non permanent characteristics. In this work different transmission lines with voltage levels of 345 kV up to 765 kV and with 150 km up to 900 km length are
