Electric and magnetic field levels generated by AC power systems - Measurement procedures with regard to public exposure

IEC 62110:2009 establishes measurement procedures for electric and magnetic field levels generated by AC power systems to evaluate the exposure levels of the human body to these fields. This standard is not applicable to DC power transmission systems. IEC 62110:2009 is applicable to public exposure in the domestic environment and in areas accessible to the public. It specifies fundamental procedures for the measurement of fields, and, with regard to human exposure, for obtaining a field value that corresponds to a spatial average over the entire human body. IEC 62110:2009 is not applicable to occupational exposure associated with, for example, the operation and/or maintenance of the power systems. Such exposure may occur when working inside a distribution or transmission substation, a power plant, in a manhole or a tunnel for underground cables, or on an overhead line tower or pole.

Elektrische und magnetische Felder, die von Wechselstrom-Energieversorgungssystemen erzeugt werden - Messverfahren im Hinblick auf die Exposition der Allgemeinbevölkerung

Champs électriques et magnétiques générés par les systèmes d'alimentation à courant alternatif - Procédures de mesure des niveaux d'exposition du public

La CEI 62110:2009 établit des procédures de mesure des niveaux de champs électriques et magnétiques générés par des systèmes d'alimentation à courant alternatif, afin d'évaluer les niveaux d'exposition du corps humain à ces champs. La présente norme ne s'applique pas aux systèmes de transport à courant continu. La CEI 62110:2009 s'applique à l'exposition humaine dans l'environnement domestique et dans les lieux qui sont accessibles augrand public. Elle spécifie les procédures fondamentales destinées à mesurer des champs, et concernant l'exposition humaine, à obtenir une valeur de champ correspondant à la moyenne spatiale sur l'ensemble du corps humain. La CEI 62110:2009 s'applique pas à l'exposition en milieu professionnel associée, par exemple, à l'exploitation et/ou la maintenance des systèmes d'alimentation. Une telle exposition peut avoir lieu lorsqu'on travaille dans un poste électrique de distribution ou de transport, une centrale, dans un puis d'accès ou un tunnel pour câbles souterrains, ou sur un poteau ou un pylône de ligne aérienne.

Merilni postopki za merjenje nivoja električnih in magnetnih polj, ki jih generirajo izmenični napajalni sistemi, z vidika izpostavljenosti ljudi (IEC 62110:2009)

Ta mednarodni standard vzpostavlja merilne postopke za merjenje električnih in magnetnih polj, ki jih generirajo izmenični napajalni sistemi, za vrednotenje ravni izpostavljenosti človeškega telesa tem poljem. Ta standard ne velja za enosmerne sisteme prenosa električne energije. Ta mednarodni standard velja za javno izpostavljenost v domačem okolju in na območjih, dostopnih javnosti. Ta standard določa bistvene postopke za merjenje polj in, z vidika izpostavljenosti ljudi, za pridobivanje vrednosti polja, ki ustreza prostorskemu povprečju za celotno človeško telo.  Ta standard ne velja za izpostavljenost pri delu, povezano na primer z delovanjem in/ali vzdrževanjem napajalnih sistemov. Do takšne izpostavljenosti lahko pride med delom v razdelilni postaji za distribucijo ali prenos električne energije, v elektrarni, vstopnem jašku ali tunelu za podzemne kable ali na nadzemnih električnih stolpih ali drogovih.
