EN 50124-2:2001

Railway applications - Insulation coordination - Part 2: Overvoltages and related protection

This European Standard applies to:  Fixed installations (downstream 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 standard gives simulation and/or test requirements for protection against transient overvoltages of such equipment. Long-term overvoltages are not treated in this document.
