This document specifies the main characteristics of the voltage at a network user's supply terminals in public low voltage, medium, high, and extra-high voltage AC electricity networks under normal operating conditions. This document specifies the limits or values within which the voltage characteristics can be expected to remain at any supply terminal in public European electricity networks, only. Industrial networks are excluded from the scope of EN 50160.
NOTE 1   If non-public networks (e.g. residential quarters, energy communities, office centres, shopping centres) have similar end-users as public networks, it is strongly advised to apply the same requirements as for public networks.
This document does not apply under abnormal operating conditions, including the following:
a)   a temporary supply arrangement to keep network users supplied during conditions arising as a result of a fault, maintenance and construction work, or to minimize the extent and duration of a loss of supply;
b)   in the case of non-compliance of a network user's installation or equipment with the relevant standards or with the technical requirements for connection, established either by the public authorities or the network operator, including the limits for the emission of conducted disturbances;
NOTE 2   A network user’s installation can include load and generation.
c)   in exceptional situations, in particular:
1)   exceptional weather conditions and other natural disasters;
2)   third party interference;
3)   acts by public authorities,
4)   industrial actions (subject to legal requirements);
5)   force majeure;
6)   power shortages resulting from external events.
The voltage characteristics given in this document refer to conducted disturbances in public electric power networks. They are not intended to be used as electromagnetic compatibility (EMC) levels or product emission limits.
Power quality is related to EMC in several ways - especially because compliance with power quality requirements depends on the control of cumulative effect of electromagnetic emissions from all/multiple equipment and/or installations. Therefore, the voltage characteristics given in this document gives guidance for specifying requirements in equipment product standards and in installation standards.
NOTE 3   The performance of equipment might be impaired if it is subjected to supply conditions which are not specified in the equipment product standard.
NOTE 4   This document can be superseded in total or in part by the terms of a contract between the individual network user and the network operator.
The sharing of complaint management and problem mitigation costs between the involved parties is outside the scope of EN 50160.
Measurement methods to be applied in this document are described in EN 61000-4-30.

This document specifies requirements for protective provisions against the effects of stray currents, which result from the operation of DC electric traction power supply systems.
As several decades' experience has not shown evident corrosion effects from AC electric traction power supply systems, this document only deals with stray currents flowing from a DC electric traction power supply system.
This document applies to all metallic fixed installations which form part of the traction system, and also to any other metallic components located in any position in the earth, which can carry stray currents resulting from the operation of the railway system.
This document applies to all new DC lines and to all major revisions to existing DC lines. The principles can also be applied to existing electrified transportation systems where it is necessary to consider the effects of stray currents.
This document does not specify working rules for maintenance but provides design requirements to allow maintenance.
The range of application includes:
a)   railways,
b)   guided mass transport systems such as:
1)   tramways,
2)   elevated and underground railways,
3)   mountain railways,
4)   magnetically levitated systems, which use a contact line system, and
5)   trolleybus systems,
c)   material transportation systems.
This document does not apply to
a)   electric traction power supply systems in underground mines,
b)   cranes, transportable platforms and similar transportation equipment on rails, temporary structures (e.g. exhibition structures) in so far as these are not supplied directly from the contact line system and are not endangered by the electric traction power supply system,
c)   suspended cable cars,
d)   funicular railways.

This document specifies requirements for the protective provisions relating to electrical safety in fixed installations, when it is reasonably likely that hazardous voltages or currents will arise for people or equipment, as a result of the mutual interaction of AC and DC electric power supply traction systems.
It also applies to all aspects of fixed installations that are necessary to ensure electrical safety during maintenance work within electric power supply traction systems.
The mutual interaction can be of any of the following kinds:
—   parallel running of AC and DC electric traction power supply systems;
—   crossing of AC and DC electric traction power supply systems;
—   shared use of tracks, buildings or other structures;
—   system separation sections between AC and DC electric traction power supply systems.
The scope is limited to galvanic, inductive and capacitive coupling of the fundamental frequency voltages and currents and their superposition.
This document applies to all new lines, extensions and to all major revisions to existing lines for the following electric traction power supply systems:
a)   railways;
b)   guided mass transport systems such as:
1)   tramways,
2)   elevated and underground railways,
3)   mountain railways,
4)   magnetically levitated systems, which use a contact line system,
5)   trolleybus systems, and
6)   electric traction power supply systems for road vehicles, which use an overhead contact line system;
c)   material transportation systems.
The document does not apply to:
a)   electric traction power supply systems in underground mines;
b)   cranes, transportable platforms and similar transportation equipment on rails, temporary structures (e.g. exhibition structures) in so far as these are not supplied directly or via transformers from the contact line system and are not endangered by the electric traction power supply system for railways;
c)   suspended cable cars;
d)   funicular railways;
e)   procedures or rules for maintenance.
The rules given in this document can also be applied to mutual interaction with non-electrified tracks, if hazardous voltages or currents can arise from AC or DC electric traction power supply systems.
