Course Description
Classification and effects of overvoltages. Internal overvoltages: power frequency overvoltages (sudden load rejection, Ferranti effect, ground faults), switching overvoltages. External overvoltages: properties and effects of lightning, propagation of surges. Traveling wave problems: reflection and transmission of traveling waves, Bewley and Bergeron methods. Protection against overvoltages: protection devices, their selection, and installation. Protection against the lightning. High voltage insulators. Insulation coordination: definitions and classification, statistical evaluation.
