Railway applications. Insulation coordination - Overvoltages and related protection Ingestion-build-51215 designated A to D1 Scope 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
