    Abstract - (Show below) - (Hide below)

    This European Standard applies to:-fixed installations (downstream of the secondary of the substation transformer) and rolling stock equipment linked to the contact line of one of the systems defined in EN 50163;-rolling stock equipment linked to a train line.This European Standard gives simulation and/or test requirements for protection against transient overvoltages of such equipment.Long-term overvoltages are not addressed in this document.
