    Book
    Open Access
    S'ha volgut donar un tractament tan simple com ha estat possible intentant abastar les tipologies de màquines més freqüents. Així s'han obviat les demostracions conduents a l'obtenció d'alguns esquemes equivalents pensant ...
  • Optimization of surge arrester locations in overhead distribution networks 

    Bullich Massagué, Eduard; Sumper, Andreas; Villafafila Robles, Roberto; Rull Duran, Joan (2015-04-01)
    Article
    Open Access
    Lightning is considered one of the main causes of faults in overhead distribution networks. Direct strokes usually lead to flashovers due to the insulation levels that are used. Induced overvoltages caused by indirect ...
