(Main)Operation of electrical installations - Part 1: General requirements
Operation of electrical installations - Part 1: General requirements
This document is applicable to all operation of and work activity on, with, or near electrical installations.
These are electrical installations operating at voltage levels from and including extra-low voltage up to and
including high voltage.
This latter term includes those levels commonly referred to as medium and extra-high voltage.
These electrical installations are designed for the generation, transmission, conversion, distribution and
use of electrical power. Some of these electrical installations are permanent and fixed, such as a distribution
installation in a factory or office complex, others are temporary, such as on construction sites and others
are mobile or capable of being moved either whilst energised or whilst not energised nor charged. Examples
are electrically driven excavating machines in quarries or open-cast coal sites.
This document sets out the requirements for the safe operation of and work activity on, with, or near these
electrical installations. The requirements apply to all operational, working and maintenance procedures.
They apply to all non-electrical work such as building work near to overhead lines or underground cables
as well as electrical work, when there is a risk of electrical danger.
This document does not apply to ordinary persons when using installations and equipment, provided that
the installations and equipment comply with relevant standards and are designed and installed for use by
ordinary persons.
This document has not been developed specifically to apply to the electrical installations listed below.
However, if there are no other rules or procedures, the principles of this document could be applied to them:
— on any aircraft and hovercraft moving under its own power, (these are subject to International Aviation
laws which take precedence over national laws in these situations);
— on any sea going ship moving under its own power, or under the direction of the master, (these are
subject to International Marine laws which take precedence over national laws in these situations);
— electronic telecommunications and information systems;
— electronic instrumentation, control and automation systems;
— at coal or other mines;
— on off-shore installations subject to International Marine laws;
— on vehicles;
— on electric traction systems;
— on experimental electrical research work.
Betrieb von elektrischen Anlagen - Teil 1: Allgemeine Anforderungen
Exploitation des installations électriques - Partie 1: Exigences générales
Le présent document s'applique à toute exploitation et opération sur ou à proximité des installations électriques. Il s'agit d'installations électriques qui fonctionnent à des niveaux de tension depuis la très basse tension incluse jusqu'à la haute tension incluse.
Ce dernier terme inclut les niveaux qui correspondent couramment aux appellations de moyenne et de très haute tension.
Ces installations électriques sont conçues pour la production, le transport, la transformation, la distribution et l'utilisation de l'énergie électrique. Certaines de ces installations électriques sont permanentes et fixes, par exemple une installation de distribution dans une usine ou dans un immeuble de bureaux, d'autres sont temporaires, par exemple sur des chantiers de construction, et d'autres sont mobiles ou susceptibles d'être déplacées, que ces installations soient sous tension ou hors tension et hors charge. Les machines excavatrices électriques en carrières ou mines de charbon à ciel ouvert constituent des exemples.
Le présent document définit les exigences pour l'exploitation et les opérations en toute sécurité sur ou à proximité des installations électriques. Les exigences s'appliquent à toutes les procédures d'exploitation, de travail et de maintenance. Elles s'appliquent, lorsqu'il existe un risque de danger électrique, à l'ensemble des travaux non électriques comme les travaux de construction à proximité des lignes aériennes ou des câbles souterrains, aussi bien qu'aux travaux électriques.
Le présent document ne s'applique pas aux personnes ordinaires lors de l'utilisation d'installations et d'équipements qui satisfont aux normes correspondantes et qui sont conçus et installés pour être utilisés par des personnes ordinaires.
Le présent document n'a pas été élaboré spécialement pour s'appliquer aux installations énumérées ci après. Cependant, en l'absence d'autres règles ou procédures, les principes indiqués dans le présent document peuvent être appliqués à ces installations:
— les avions ou aéroglisseurs alimentés par leur propre source d'énergie (ceux-ci sont assujettis aux lois de l'Aviation Internationale qui ont priorité sur les lois nationales dans ces situations);
— les bateaux alimentés par leur propre source d'énergie, ou sous la direction de leur maître de bord (ceux-ci sont assujettis aux lois de la Marine Internationale qui ont priorité sur les lois nationales dans ces situations);
— les systèmes électroniques de télécommunication et d'information;
— les systèmes électroniques d'instrumentation, de contrôle et d'automatisation;
— les mines de charbon ou autres mines;
— les installations en mer assujetties aux lois de la Marine Internationale;
— les véhicules;
— les systèmes de traction électrique;
— les travaux expérimentaux de recherche électrique.
Obratovanje električnih postrojev - 1. del: Splošne zahteve
Ta dokument se uporablja za vse obratovanje in delo na električnih inštalacijah, z njimi oziroma v njihovi bližini.
Te električne inštalacije obratujejo na različnih ravneh napetosti, in sicer od vključno izjemno nizkonapetostnih do vključno visokonapetostnih.
Slednji izraz vključuje ravni, običajno imenovane srednje in izredno visokonapetostne.
Te električne inštalacije so zasnovane za proizvodnjo, prenos, pretvorbo in distribucijo ter uporabo električne energije. Nekatere od njih, na primer inštalacije za distribucijo v tovarniških ali pisarniških kompleksih, so stalne in fiksne, nekatere pa začasne, na primer tiste na gradbiščih, spet druge pa so mobilne ali primerne za premikanje, ko so ali niso pod napetostjo oziroma napajanjem. Primer so stroji za izkopavanje na električni pogon, ki se uporabljajo v kamnolomih ali odprtih kopih premoga.
Ta dokument določa zahteve za varno obratovanje in delo na električnih inštalacijah, z njimi oziroma v njihovi bližini. Zahteve se uporabljajo za vse obratovalne, delovne in vzdrževalne postopke.
Uporabljajo se za vsa neelektrična dela, na primer za gradbena dela v bližini voznih vodov ali podzemnih kablov, pa tudi za električna dela, pri katerih obstaja tveganje nevarnosti električnega toka.
Ta dokument se ne uporablja za običajne osebe, ki uporabljajo inštalacije in opremo, pod pogojem, da so te inštalacije in oprema skladne z ustreznimi standardi ter so zasnovane in nameščene, da bi jih uporabljale običajne osebe.
Ta dokument ni bil posebej pripravljen, da bi se uporabljal za spodaj navedene električne inštalacije,
vendar se lahko načela, opisana v tem dokumentu, uporabljajo tudi zanje, če ne obstajajo druga pravila ali postopki:
– inštalacije na vseh zrakoplovih in vozilih na zračno blazino, ki se premikajo na lastni pogon (zanje se uporablja mednarodna zakonodaja s področja letalstva, ki ima v teh primerih prednost pred nacionalno zakonodajo);
– inštalacije na vseh morskih plovilih, ki se premikajo na lastni pogon (zanje se uporablja mednarodna zakonodaja s področja pomorstva, ki ima v teh primerih prednost pred nacionalno zakonodajo);
– elektronske telekomunikacije in informacijske sisteme;
– elektronske instrumente ter nadzorne in samodejne sisteme;
– inštalacije v premogovnikih ali drugih rudnikih;
– inštalacije na morju, za katere se uporablja mednarodna zakonodaja s področja pomorstva;
– inštalacije v vozilih;
– inštalacije v sistemih električne vleke;
– inštalacije, ki se uporabljajo pri eksperimentalnem raziskovalnem delu, pri katerem se uporablja električna energija.
