Definitions
For the purposes of this European Standard, the terms and definitions given in EN 50122-1, EN 50160
and the following apply.
--`,,,``,-`-`,,`,,`,`,,`---
3.1
electric traction system
railway electrical distribution network used to provide energy for rolling stock
NOTE The system may comprise
–
contact line systems,
–
return circuit of electric traction systems,
–
running rails of non-electric traction systems, which are in the vicinity of, and conductively connected to the running rails of an
electric traction system,
–
electrical installations, which are supplied from contact lines either directly or via a transformer,
–
electrical installations in power plants and substations, which are utilized solely for generation and distribution of power directly
to the contact line,
–
electrical installations of switching stations.
[EN 50122–1]
3.2
voltage U
potential at the train’s current collector or elsewhere on the contact line, measured between the contact
line and the return circuit.
The values considered in this European Standard are the mean value of d.c. voltage or the r.m.s. value of
the fundamental a.c. voltage
3.3
nominal voltage Un
designated value for a system
3.4
highest permanent voltage Umax1
maximum value of the voltage likely to be present indefinitely
3.5
highest non permanent voltage Umax2
maximum value of the voltage likely to be present as highest non permanent voltage for a limited period
of time
3.6
highest long term overvoltage Umax3
Voltage defined as the highest value of the long-term overvoltage for t = 20 ms. This value is independent
from frequency
3.7
lowest permanent voltage Umin1
minimum value of the voltage likely to be present indefinitely
3.8
lowest non permanent voltage Umin2
minimum value of the voltage likely to be present for a limited period of time

EN 50163:2004
–6–
3.9
long-term overvoltage
overvoltage higher than Umax2 lasting typically more than 20 ms, due to low impedance phenomena e.g. a
rise in substation primary voltage
--`,,,``,-`-`,,`,,`,`,,`---
NOTE Such overvoltages are independent of line load and may be described by a voltage-time curve only. See Annex A for
information on this curve.
3.10
voltage variation
increase or decrease of voltage normally due to variation of the total load of a distribution system or a part
of it
NOTE Adapted from EN 50160.
3.11
rapid voltage change
single rapid variation of the r.m.s. value of a voltage between two consecutive levels which are sustained
for definite but unspecified durations
NOTE Adapted from EN 50160.
3.12
supply voltage dip
sudden reduction of the supply voltage to a value less than Umin2, followed by a voltage recovery after a
short period of time. Conventionally the duration of a voltage dip is between 10 ms and 1 min. The depth
of a voltage dip is defined as the difference between the minimum r.m.s. voltage during the voltage dip
and the nominal voltage Un. Voltage changes which do not reduce the supply voltage to less than Umin2
are not considered to be dips
3.13
supply interruption
condition in which the voltage at the supply-terminals is lower than 1 % of the nominal voltage Un.
A supply interruption can be classified as
–
prearranged, when consumers are informed in advance, to allow the execution of scheduled works
on the distribution systems, or
–
accidental, caused by permanent or transient faults, mostly related to external events, equipment
failures or interference. An accidental interruption is classified as
•
a long interruption (longer than 3 min) caused by a permanent fault,
•
a short interruption (up to 3 min) caused by a transient fault (see EN 50160).
3.14
contact line
conductor system for supplying electric energy to vehicles through current-collecting equipment
[IEC 60050-811-33-01]
NOTE Contact line covers overhead contact line and conductor rail as defined in EN 50119 and EN 50122-1.
3.15
(traction) substation
installation, the main function of which is to supply a contact line system, at which the voltage of a primary
supply system, and in certain cases the frequency, is converted to the voltage and frequency of the
contact line

design. Power supply equipment is operated according to standard rules.
NOTE Standard rules may vary depending on the infrastructure manager’s policy.
3.17
abnormal operating conditions
either higher traffic loads or outage of power supply equipment outside the standard rules
NOTE Under these conditions, traffic may not operate to the design timetable.

Future d.c. traction systems for tramways and local railways should conform with system nominal voltage of 750 V,
1 500 V or 3 000 V.
b
Special national conditions for Belgium, see Annex B.

b) the duration of voltages between Umax1 and Umax2 shall not exceed 5 min;
c) the voltage of the busbar at the substation at no load condition shall be less than or equal to Umax1.
For d.c. substations it is acceptable to have this voltage at no load condition less than or equal to
Umax2, knowing that when a train is present, the voltage at this train’s pantograph (s) shall be in
accordance with Table 1 and its requirements;
d) under normal operating conditions, voltages shall lie within the range Umin1 ≤ U ≤ Umax2;

e) under abnormal operating conditions the voltages in the range Umin2 ≤ U ≤ Umin1 in Table 1 shall not
cause any damages or failures.
NOTE 1 The use of train power limitation devices on board may limit the presence of low voltage on the overhead line (see
EN 50388).
f)
if voltages between Umax1 and Umax2 are reached, it shall be followed by a level below or equal to
Umax1, for an unspecified period.
Voltages between Umax1 and Umax2 shall only be reached for non permanent conditions such as
–
regenerative braking,
–
move of voltage regulation systems such as mechanical tap changer.
g) lowest operational voltage: under abnormal operating conditions Umin2 is the lowest limit of the contact
line voltage for which the rolling stock is intended to operate.
NOTE 2 Recommended values for undervoltage tripping: The setting of undervoltage relays in fixed installations or on board
rolling stock should be set from 85 % to 95 % of Umin2.
4.2
Frequency
The frequency of the 50 Hz electric traction system is imposed by the three phase grid. Therefore, the
values stated by EN 50160 are applicable. The frequency of the 16,7 Hz electric traction system (except
for synchronous- synchronous converters) is not imposed by the three phase grid.
NOTE 1 About the 16,7 Hz electric traction system, strictly considered, the frequency corresponds to 16⅔ Hz. In order to simplify
the denomination of the system, it is agreed to state the frequency as 16,7 Hz. This denomination is used in this European
Standard.
The frequencies on a.c. railway power systems and their permissible limits are shown thereafter.
Under normal operating conditions, the mean value of the fundamental frequency measured over 10 s
shall be within a range of the HV supply network.

NOTE 2 In practice, the variation of frequency is more closely controlled in Europe than stated above. Vehicles will operate only
within the frequency tolerances for 15 kV 16,7 Hz from 16,17 Hz to 17 Hz and for 25 kV/50 Hz range from 49 Hz to 51 Hz. If the
frequency is out of this range, the vehicles performance may be reduced or the vehicle drives shall be disconnected.
The effects of the frequency variations may be examined by the railway operators to ensure the absence of harmful consequences
on the train signalling.

France
4.1
For existing urban networks which have complied with the relevant national
standard before 1996-03-01 ("dop" of EN 50163:1995), this previous standard
may continue to apply for those networks within the context of partial renewals, as
long as dualness is demonstrable for 15 years after 1996-03-01.
NOTE From EN 50163:1995.
United Kingdom
4.1
For existing networks, which are not compliant with this European Standard, the
values of lowest non-permanent voltage Umin2, for normal traffic loads but where
there are power supply equipment outages outside design standards, shall be as
follows:
– 400 V, instead of 500 V on the 750 V British third rail d.c. network
– 14 000 V on the 25 000 V network, minimum voltage at which a train shall
continue to operate for up to ten minutes without being damaged
– 12 500 V on the 25 000 V network, minimum voltage at which a train shall
continue to operate for up to two minutes without being damaged.
For existing networks where there is no provision for voltage regulation systems,
Umax1 may be exceeded.

Annex C
(informative)
Changes, interruptions and distortion of voltages
C.1
Rapid voltage changes
Rapid voltage changes within the ranges set up in Table 1 are an inherent part of railway electrification
due to changes in traction load, configuration of traction power supply network or configuration of the
public or railway power supply network.
C.2
Contact Line voltage dips
Voltage dips are caused by faults on the contact line or on public distribution systems.
The majority of voltage dips have a duration less than 1 s and a depth less than 50 % of Un.
C.3
Short interruptions of the voltage
Under normal operating conditions, voltage short interruptions are generally caused by circuit breakers
tripping and auto-reclosing operations after the detection of faults. The auto-reclosing cycles are
described in switchgear standards (EN 50123 series, EN 50152 series).
Information is also given in the EN 50388.
The annual occurrence of short interruptions of the supply voltage ranges from up to a few tens to up to
several hundreds. The duration of approximately 70 % of the short interruptions may be less than 10 s.
C.4
Long interruptions of the voltage
Accidental interruptions are usually caused by, external events or actions which cannot be prevented by
the infrastructure manager.
It is not possible to indicate typical values for duration of long interruptions.
Under normal operating conditions the annual frequency of voltage interruptions longer than three
minutes may be less than some units.
Indicative values are not given for prearranged interruptions, because they are announced in advance.
C.5
Distortion of the voltage (a.c. and d.c.)
The voltage is distorted by traction and auxiliary loads, converter substations and the public distribution
system.
This results in high and low frequency harmonics which may include, only for a.c., offset (transient) and
extra zero crossings.

Testing
C.6.1
General
The parameters for voltage changes are set out in Clauses C.1, C.2, C.3 and C.4 (technical). Testing and
acceptance requirements are detailed below.
C.6.2
Rolling stock
The requirements for testing of rolling stock after completion of construction and before entry into service
are set out in EN 50215, 9.2. (e) and (f), 9.12, 9.14.2 and 9.15. See also the product standards.

Clauses C.1, C.2, C.3 and C.4 (technical) do not require any
specific type or routine test. However after the introduction of
service, if a problem is noted which is related to the quality of the
voltage, then it is suggested that the voltage should be monitored
over a representative period after the introduction of full normal
service. The results should be analysed as follows.
Rapid voltage changes and contact line voltage dips.
Capture voltages below Umin2 and analyse data to give voltage
level as a percentage of Un and duration in milliseconds.
Tabulate worst cases in terms of lowest voltage levels and
duration. Identify any faults or switching on the railway
electrification or public distribution systems at the time of the
tabulated changes.
•
Short and long interruptions of the voltage
Capture all voltage interruptions and record time of each
interruption.
Tabulate voltage interruptions by number in the following time
bands:
– < 10 s
–
10 s - 1 min
–
1 min - 3 min
–
> 3 min
Give time for any interruptions exceeding 3 min but ignore any
pre-arranged interruptions.
