Introduction

This European Standard is part of the EN 50124 series, Railway applications – Insulation coordination.

EN 50124 consists of two parts:

— EN 50124-1, Railway applications - Insulation coordination - Part 1: Basic requirements -

Clearances and creepage distances for all electrical and electronic equipment;

— EN 50124-2, Railway applications - Insulation coordination - Part 2: Overvoltages and related

protection.

This Part 2 deals with the shortest durations of overvoltages referred to as Zone A and Zone B in

Figure A.1 in Annex A.

1 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 document.
2 Normative references

The following documents, in whole or in part, are normatively referenced in this document and are

indispensable for its application. For dated references, only the edition cited applies. For undated

references, the latest edition of the referenced document (including any amendments) applies.

EN 50163:2004, Railway applications - Supply voltages of traction systems
EN 50533, Railway applications - Three-phase train line voltage characteristics

EN 60099-4, Surge arresters - Part 4: Metal-oxide surge arresters without gaps for a.c. systems (IEC

60099-4)
3 Terms and Definitions
For the purposes of this document, the following terms and definitions apply:

NOTE The definitions are in accordance with those of EN 50163 (see also Annex A). Long-term, medium-

term and short-term overvoltages are equivalent to respectively temporary, switching and lightning overvoltages

defined in EN 60664–1.
3.1 Voltages
3.1.1
overvoltage

voltage having a peak value exceeding the corresponding peak value of maximum steady-state

voltage at normal operating conditions
[SOURCE: EN 60664-1]
3.1.2
long-term overvoltage
overvoltage at relatively long duration due to voltage variations

Note 1 to entry: A long-term overvoltage is independent of the network load. It is characterized by a voltage/time

curve.
---------------------- Page: 7 ----------------------
SIST EN 50124-2:2017
EN 50124-2:2017 (E)
3.1.3
transient overvoltage
short duration overvoltage of a few milliseconds or less due to current transfer

Note 1 to entry: A transient overvoltage depends on the network load. It cannot be characterized by a

voltage/time curve. Basically, a transient overvoltage is the result of a current transfer from a source to the load

(network).
3.1.4
medium-term overvoltage

transient overvoltage at any point of the system due to specific switching operation or fault

3.1.5
short-term overvoltage

transient overvoltage at any point of the system due to a specific lightning discharge

3.2
network

set of conductors fulfilling a certain function, the overvoltages of which are likely to damage the

equipment they are connected to
4 Contact line network

NOTE The provisions of this Clause 4 do not take into account rapid transient overvoltages in the

multimegahertz range such as generated by operation of vacuum circuit breakers which may require a specific

overvoltage protection.
4.1 Equipment not protected by a metal-oxide arrester

If the equipment is not protected by a metal-oxide arrester, the protection against overvoltages shall

take into account overvoltages limited only by the intrinsic insulation of the contact line and the

possible presence of other types of arrester or spark gaps.
4.2 Equipment protected by a metal-oxide arrester
4.2.1 General

If the supplier wants to benefit from the presence of a metal-oxide arrester for reducing constraints

resulting from 4.1, the supplier shall perform a simulation of the behaviour of the equipment with its

protection against overvoltages according to 4.2
