What is BS EN 50152-3-1-Devices for specific use in A.C. traction systems about?
BS EN 50152-3 is a European standard on particular requirements for A.C. switchgear that discusses devices for specific use in A.C. traction systems. BS EN 50152-3-1 is the first subpart of the third part of a multi-part series that applies to new low voltage devices for measurement, control, and protection that are:
- For indoor or outdoor fixed installations in traction systems operated in conjunction with high voltage equipment with an A.C. line voltage and frequency as specified in EN 50163
BS EN 50152-3-1 also applies to measurement, control, and protective devices other than low voltage devices and not covered by a specific railway product standard as far as reasonably possible.
Who is BS EN 50152-3-1-Devices for specific use in A.C. traction systems for?
BS EN 50152-3-1 on the devices for specific use in A.C. traction systems are relevant to:
- A.C. switchgear manufacturers
- Personnel or staff in charge of A.C. traction systems
- Regulatory authorities
Why should you use BS EN 50152-3-1-Devices for specific use in A.C. traction systems?
In an electric power system, A.C. switchgear is composed of electrical disconnected switches, fuse, or circuit breakers used to control, protect, and isolate electrical equipment. Switchgear is used both to de-energize equipment to allow it to be done and to clear faults downstream.
BS EN 50152-3-1 guideline assists you with requirements on voltage detection systems, devices at a supply voltage of a traction system, and protection devices for measurement, control, and protection devices for specific use in A.C. traction systems.
With obedience, and compliance of BS EN 50343 you can get appropriate guidance on measurement, control, and protection devices for specific use in A.C. traction systems and ensure that these devices are functioning well in the field.
What’s changed since the last update?
BS EN 50152-3-1:2017 supersedes EN 50152-3-1:2003, which is withdrawn. BS EN 50152-3-1:2017 has made some technical changes compared to EN 50152-3-1:2003. These includes:
- It has been completely reworked to distinguish between requirements, Clauses 4 and 5, and application guides, annexes
- It has been completely reworked to include requirements on devices e.g., control and protection relays not included before
- It has been reworked to remove parts already included in other standards, e.g., EN 50633 protection principles
