| 적용범위 | Scope Interest in magnetic fields has been stimulated in recent years by concern over the physiological effects they may have on humans and animals and the deleterious effects they have on the performance of some electrical equipment, particularly video display units. Investigations have yielded results which are presented in this report as reference values.? Note 1 - The European Union EMC Directive has prompted magnetic field measurements, particularly in respect of the commercial office environments associated with supply authority substations and electrical distribution systems within buildings. Supply authorities have sponsored most of the work and the results are generally within the frequency range of 50 Hz to 2 kHz, and presented as r.m.s. values. There is, however, a need to have some knowledge about d.c. fields and the fields up to 150 kHz as they may interfere with some types of equipment.? Note 2 - Most of the magnetic field data in this report is associated with sinusoidal current sources and r.m.s. values may be assumed unless otherwise stated. Power supply systems operating at voltages less than or equal to 1 000 V are designated low-voltage, those above 1 000 V and up to 35 kV are designated medium-voltage, and those in excess of 35 kV are designated high-voltage.? --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------? Domaine d’application Les champs magn?tiques ont ?t? l'objet d'un regain d'int?r?t au cours de ces derni?res ann?es en raison des effets physiologiques qu'ils peuvent avoir sur les ?tres humains et les animaux et des effets d?favorables qu'ils ont sur le fonctionnement de certains ?quipements ?lectriques, notamment les ?crans de visualisation. Les r?sultats des recherches sont pr?sent?s dans ce rapport comme valeurs de r?f?rence.? NOTE 1 - La Directive CEM de la Commission Europ?enne a suscit? de faire des mesures de champs magn?tiques, particuli?rement dans des environnements de bureaux commerciaux ? proximit? de postes appartenant ? des compagnies d'?lectricit? ainsi que dans des environnements de r?seaux de distribution d'?lectricit? ? l'int?rieur des b?timents. Les distributeurs d'?lectricit? ont support? financi?rement la plupart des travaux et les r?sultats se situent g?n?ralement dans la gamme de fr?quence allant de 50 Hz ? 2 kHz et sont pr?sent?s comme des valeurs efficaces. Il est toutefois n?cessaire de conna?tre quelque peu les champs magn?tiques jusqu'? 150 kHz car ils interf?rent avec certains types d'appareils.? NOTE 2 - La plupart des valeurs de champs magn?tiques indiqu?es dans ce rapport correspondent ? des sources de courant sinuso?dal et on peut les consid?rer comme des valeurs efficaces sauf indications contraires. Les r?seaux d'alimentation de tensions inf?rieures ou ?gales ? 1 000 V sont consid?r?s comme des r?seaux basse tension, ceux exploit?s ? des tensions sup?rieures ? 1 000 V allant jusqu'? 35 kV comme des r?seaux moyenne tension et enfin ceux exploit?s ? des tensions sup?rieures ? 35 kV comme des r?seaux haute tension. |
