Railway applications - Electromagnetic compatibility - Part 5: Emission and immunity of fixed power supply installations and apparatus
This European Standard applies to emission and immunity aspects of EMC for electrical and electronic apparatus and systems intended for use in railway fixed installations for power supply. This includes the power feed to the apparatus, the apparatus itself with its protective control circuits, trackside items such as switching stations, power autotransformers, booster transformers, substation power switchgear and power switchgear to other longitudinal and local supplies. Filters operating at railway system voltage (for example, for harmonic suppression or power factor correction) are not included in this standard since each site has special requirements. Filters would normally have separate enclosures with separate rules for access. If electromagnetic limits are required, these will appear in the specification for the equipment. If a port is intended to transmit or receive for the purpose of radio communication (intentional radiators, e.g. transponder systems), then the radiated emission requirement in this standard are not intended to be applicable to the intentional transmission from a radio-transmitter as defined by the ITU. The frequency range considered is from DC to 400 GHz. No measurements need to be performed at frequencies where no requirement is specified. Emission and immunity limits are given for items of apparatus which are situated: a) within the boundary of a substation which delivers electric power to a railway; b) beside the track for the purpose of controlling or regulating the railway power supply, including power factor correction; c) along the track for the purpose of supplying electrical power to the railway other than by means of the conductors used for contact current collection, and associated return conductors. Included are high voltage feeder systems within the boundary of the railway which supply substations at which the voltage is reduced to the railway system voltage; d) beside the track for controlling or regulating electric power supplies to ancillary railway uses. This category includes power supplies to marshalling yards, maintenance depots and stations; e) various other non-traction power supplies from railway sources which are shared with railway traction. The immunity levels given in this standard apply for: - vital equipment such as protection devices; - equipment having connections to the traction power conductors; - apparatus inside the 3 m zone; - ports of apparatus inside the 10 m zone with connection inside the 3 m zone; - ports of apparatus inside the 10 m zone with cable length > 30 m. Apparatus and systems which are in an environment which can be described as residential, commercial or light industry, even when placed within the physical boundary of the railway substation, shall comply with EN 61000-6-1:2007 for immunity and EN 61000-6-3:2007 for emission requirements. Excluded from the immunity requirements of this standard is power supply apparatus which is intrinsically immune to the tests defined in Tables 1 to 6. NOTE An example is an 18 MVA 230 kV to 25 kV power supply transformer. These specific provisions are to be used in conjunction with the general provisions in EN 50121-1. This part of the standard covers requirements for both apparatus and fixed installations. The sections for fixed installations are not relevant for CE marking.

Introduction
The requirements of this standard have been specified so as to ensure a level of electromagnetic
emission which will cause minimal disturbance to other equipment. The levels, however, do not cover
the following cases:
a) which may occur with an extremely low probability of occurrence in any location;
b) where highly susceptible apparatus will be used in close proximity of the equipment covered by
this standard, in which case further measures may have to be taken.
The emission limits given are on the basis that the equipment of the product family range is installed in
railway substation areas.

1 Scope
This document applies to emission and immunity aspects of EMC for electrical and electronic
apparatus and systems intended for use in railway fixed installations for power supply. This includes
the power feed to the apparatus, the apparatus itself with its protective control circuits, trackside items
such as switching stations, power autotransformers, booster transformers, substation power
switchgear and power switchgear to other longitudinal and local supplies.
Filters operating at railway system voltage (for example, for harmonic suppression or power factor
correction) are not included in this document since each site has special requirements. Filters would
normally have separate enclosures with separate rules for access. If electromagnetic limits are
required, these will appear in the specification for the equipment.
The frequency range considered is from DC to 400 GHz. No measurements need to be performed at
frequencies where no requirement is specified.
Emission and immunity limits are given for items of apparatus which are situated:
a) within the boundary of a substation which delivers electric power to a railway;
b) beside the track for the purpose of controlling or regulating the railway power supply, including
power factor correction;
c) along the track for the purpose of supplying electrical power to the railway other than by means of
the conductors used for contact current collection, and associated return conductors. Included are
high voltage feeder systems within the boundary of the railway which supply substations at which
the voltage is reduced to the railway system voltage;
d) beside the track for controlling or regulating electric power supplies to ancillary railway uses. This
category includes power supplies to marshalling yards, maintenance depots and stations;
e) various other non-traction power supplies from railway sources which are shared with railway
traction.
These specific provisions are to be used in conjunction with the general provisions in EN 50121-1.

4 Performance criteria
A functional description and a definition of the specific performance criteria of the equipment under test
(EUT), identifying acceptable degradation from normal performance during or as a consequence of
immunity testing, shall be provided in the equipment’s test specification and noted in the test report.
Acceptable degradation is a deviation of performance of the equipment that a reasonable user
accepts, when used as intended.
NOTE 1: Generally, the acceptable degradation of performance can be determined from an understanding of the
purpose of the equipment (e.g. from its functional description, documentation or common specifications for that
type of equipment).
The EUT’s specific performance criteria shall be consistent with the following general criteria for each
test as specified in Table 2 to Table 6:
Performance criterion A:
During and after the immunity test, the equipment shall;
— continue to operate and to remain controllable as intended within the identified acceptable
degradation from normal performance,
— not unintentionally change its operating state,
— not unintentionally change any critical stored data.
Performance criterion B:
The immunity test shall not result in;
— the mode of operation after the test being different to that at the beginning of the test,
— unintentional change to critical stored data
After the immunity test, the equipment shall operate as intended.
Performance criterion C:
The immunity test may result in loss of function, provided the function is self-recoverable, or can be
restored by the operation of the controls by the user. A reboot or re-start operation is allowed. The
immunity test shall not result in an unintentional change to critical stored data.
NOTE 2: critical data includes data previously saved by the user.

5 Emission tests and limits
5.1 Emission from the substation to the outside world
Limit values for this emission, over the frequency range 150 kHz to 1 GHz are given in EN 50121-2.
Guidance values are given in EN 50121-2 for emission of DC and power frequency magnetic fields.
Conductors (overhead or underground) between the substation and the railway are part of the railway
installation, but because of their wide variety of positions and ampere loadings, limit values cannot be
set for the magnetic fields which they produce.
No limits are set for emissions into the active space of the underground railway due to the complexities
of obtaining measurements in the confined space and the lack of a precise method of relating the
measured values to the degree of disturbance which other apparatus would suffer.
No measurements are necessary for total underground railway systems with no surface operation.
5.2 Emission test for apparatus operating at less than 1 000 V rms AC
The emission limits for apparatus covered by this standard which is supplied with electrical power at a
voltage below 1 000 V rms are given on a port by port basis in EN IEC 61000-6-4.
5.3 Emission values within the boundary of the substation
Because there is such a wide variety of options for the design and the construction of the substation,
limits are not given for emission within the general space inside the boundary of the substation.
Practical measurements have been made and guidance values are given in Annex A. These are for
information only a
