Fixed installations for railway applications - Electrical safety, earthing and the return circuit - Part 3: Mutual Interaction of AC and DC traction systems

Fixed installations for railway applications - Electrical safety, earthing and the return circuit - Part 3: Mutual Interaction of AC and DC traction systems

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.

SIST EN IEC 60077-4:2020(Main)
Railway applications - Electric equipment for rolling stock - Part 4: Electrotechnical components - Rules for AC circuit-breakers
EN IEC 60077-4:2019

In addition to the general requirements of IEC 60077-2, this part of IEC 60077 gives rules for
AC circuit-breakers, the main contacts of which are connected to AC overhead contact lines;
the nominal voltage of these circuits being in accordance with IEC 60850.
This document, together with IEC 60077-2, states specifically:
a) the characteristics of the circuit-breakers;
b) the service conditions with which circuit-breakers comply with reference to:
– operation and behaviour in normal service;
– operation and behaviour in short-circuit;
– dielectric properties;
c) the tests for confirming the compliance of the components with the characteristics under
the service conditions and the methods to be adopted for these tests;
d) the information to be marked on, or given with the circuit-breaker.
NOTE 1 Circuit-breakers which are dealt with in this document can be provided with devices for automatic
opening under pre-determined conditions other than those of overcurrent, for example, undervoltage and reversal
of power flow direction. This document does not deal with the verification of operation under such predetermined
conditions.
NOTE 2 The incorporation of electronic components or electronic sub-assemblies into electrotechnical components
is now common practice.
Although this document is not applicable to electronic equipment, the presence of electronic components does not
provide a reason to exclude such electrotechnical components from the scope.
Electronic sub-assemblies included in the circuit-breakers comply with the relevant standard for electronics
(IEC 60571).
NOTE 3 Certain of these rules, after agreement between the user and the manufacturer, are used for
electrotechnical components installed on vehicles other than rail rolling stock such as mine locomotives,
trolleybuses, etc. In this case, particular additional requirements can be necessary.
This document does not cover industrial circuit-breakers which comply with IEC 62271-100.
For these, in order to ensure satisfactory operation, this document is used to specify only the
particular requirements for rolling stock. In such cases, a specific document states the
additional requirements with which the industrial circuit-breakers comply, for example:
– either to be adapted (e.g. for control voltage, environmental conditions, etc.);
– or to be installed and used so that they do not have to endure specific rolling stock
conditions;
– or to be additionally tested to prove that these components can withstand satisfactorily the
rolling stock conditions.

The purpose of NEN-EN-IEC 60077-5 is to give additional or amended rules for high voltage (HV) fuses as a supplement to those given by IEC 60077-2. The high voltage fuses concerned are those connected into power and/or auxiliary circuits. The nominal voltage of these circuits lies between 600 V DC and 3 000 V DC, according to IEC 60850. These fuses can also be used in auxiliary AC circuits up to a nominal voltage of 1500 V. This document together with IEC 60077-2 states specifically: a) the characteristics of the fuses; b) the service conditions with which the fuses comply with reference to: - operation and behaviour in normal service; - operation and behaviour in case of short circuit; - dielectric properties. c) the tests intended for confirming the compliance of the fuse with the characteristics under the service conditions and the methods adopted for these tests; d) the information marked on, or given with, the fuse. This document does not cover parallel connection of fuses. During preparation of this document, IEC 60269-1 and IEC 60282-1 have been considered and their requirements have been kept as far as possible. This document makes reference to the general rules for electrotechnical components given in IEC 60077-2, but for general conditions reference is made directly to IEC 60077-1.

Fixed installations for railway applications - Electrical safety, earthing and the return circuit - Part 2: Provisions against the effects of stray currents caused by DC traction systems
EN 50122-2:2022/prA1:2024

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.
