BS EN 50526-3:2016

This standard BS EN 50526-3:2016 Railway application. Fixed installations. D.C. surge arresters and voltage limiting devices is classified in these ICS categories:

• 29.280 Electric traction equipment
• 29.120.50 Fuses and other overcurrent protection devices

This Application Guide supports the European Standards EN 50526‑1 and EN 50526‑2 .

Guidance is offered on the following subjects:

• the selection and installation of surge arresters;

• the selection and installation of voltage limiting devices as VLD-O and VLD-F;

• the arrangement of the surge arresters and VLDs.

Because of differences in the established, proven methods, electric traction systems of nominal voltage d.c. 600 V — d.c. 750 V are treated separately from the systems at higher nominal voltages.

This Application Guide only applies to d.c. electrified traction systems
