IEC 62128-1:2003 pdf – Railway applications – Fixed installations – Part 1: Protective provisions relating to electrical safety and earthing.
1 Scope This part of IEC 62128 specifies requirements for the protective provisions relating to electrical safety in fixed installations associated with a.c.- and d.c.-traction systems and to any installations that may be endangered by the traction power supply system. It also applies to all fixed installations that are necessary to ensure electrical safety during maintenance work within electric traction systems. NOTE Other provisions to protect work sites for maintenance purposes which are not included in this standard may be required. This standard applies to all new lines and to all major revisions to existing lines for the following electric traction systems: − railways; − guided mass transport systems such as: tramways, elevated and underground railways, mountain railways, trolleybus systems and magnetic levitated systems; − material transportation systems. This standard does not apply to: – traction systems in underground mines; – cranes, transportable platforms and similar transportation equipment on rails, temporary structures (for example 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 traction power supply system; – suspended cable cars; – funicular railways; – maintenance work. 2 Normative references The following referenced documents are indispensable for the application of this document.
