Railway applications - Fixed installations - Electrical safety, earthing and the return circuit - Part 3: Mutual Interaction of a.c. and d.c. traction systems

This European Standard 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 a.c. and d.c. electric traction systems. It also applies to all aspects of fixed installations that are necessary to ensure electrical safety during maintenance work within electric traction systems. The mutual interaction can be of any of the following kinds: – parallel running of a.c. and d.c. electric traction systems; – crossing of a.c. and d.c. electric traction systems; – shared use of tracks, buildings or other structures; – system separation sections between a.c. and d.c. electric traction systems. Scope is limited to basic frequency voltages and currents and their superposition. This European Standard does not cover radiated interferences. This European Standard applies to all new lines, extensions and to all major revisions to existing lines for the following electric traction systems: a) railways; b) guided mass transport systems such as: 1) tramways, 2) elevated and underground railways, 3) mountain railways, 4) trolleybus systems, and 5) magnetically levitated systems, which use a contact line system; c) material transportation systems. The standard does not apply to: d) mine traction systems in underground mines; e) 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 traction power supply system for railways; f) suspended cable cars; g) funicular railways; h) procedures or rules for maintenance. NOTE The rules given in this European Standard can also be applied to mutual interaction with non-electrified tracks, if hazardous voltages or currents can arise from a.c. or d.c. electric traction systems.

Železniške naprave - Stabilne naprave električne vleke - 3. del: Medsebojno vplivanje med izmeničnimi in enosmernimi sistemi vleke

Ta evropski standard določa zahteve za zaščitne ukrepe v zvezi z električno varnostjo v stabilnih napravah električne vleke, kadar obstaja razumna možnost nastanka napetosti ali tokov, nevarnih za ljudi ali opremo, kot posledica medsebojnega vplivanja med izmeničnimi in enosmernimi električnimi sistemi vleke. Velja tudi za vse vidike stabilnih naprav, potrebne za zagotavljanje električne varnosti med vzdrževalnim delom v električnih sistemih vleke. Vrste medsebojnega vplivanja so lahko naslednje: - vzporedno tekoči enosmerni in izmenični električni sistemi vleke; - križanje enosmernih in izmeničnih električnih sistemov vleke; - souporaba tirnic, stavb ali drugih konstrukcij; - deli za ločevanje sistemov med enosmernimi in izmeničnimi električnimi sistemi vleke. Področje uporabe je omejeno na napetosti in tokove osnovne frekvence in njihovo superpozicijo. Ta evropski standard ne zajema izsevanih interferenc. Ta evropski standard velja za vse nove vode, razširitve in za vse večje prenove obstoječih vodov za naslednje električne sisteme vleke: a) železniške proge, b) vodene masovne prevozne sisteme, kot so: 1) tramvajske proge, 2) nadzemne in podzemne železnice, 3) gorske železnice, 4) trolejbusni sistemi, in 5) sistemi z magnetnim lebdenjem, ki uporabljajo sistem voznih vodov, c) sisteme za prevoz materiala. Ta standard ne velja za: d) rudniške vlečne sisteme v podzemnih rudnikih, e) žerjave, prenosne platforme in podobno opremo za prevoz po tirih, začasne strukture (npr. razstavne strukture), če ne prihajajo neposredno ali preko transformatorjev  s sistema voznih vodov in jih ne ogroža napajanje sistema vleke za železnice, f) viseče kabinske žičnice, g) vzpenjače; h) postopke ali pravila za vzdrževanje.
