Introduction
This European Standard is part of the series EN 50124, Railway applications - Insulation coordination,
which consists of two parts:
− EN 50124-1 Part 1: Basic requirements - Clearances and creepage distances for all electrical
and electronic equipment;
− EN 50124-2 Part 2: Overvoltages and related protection.
This EN 50124-2 is also linked to EN 50163:1995, Railway applications - Supply voltages of traction
systems. This EN 50124-2 deals with the shortest durations of overvoltages referred to as zone A and
zone B in annex A of EN 50163, which is reproduced as an informative annex A of this EN 50124-2.

1 Scope
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.
