IEC/TR 62271-208:2009 gives practical guidance for the evaluation and documentation of the external electromagnetic fields which are generated by HV switchgear assemblies and HV/LV prefabricated substations. Basic requirements to measure or calculate the electric and magnetic fields are summarised for switchgear assemblies covered by IEC 62271-200 and IEC 62271-201, and for prefabricated substations covered by IEC 62271-202. This technical report applies to equipment rated for voltages up to and including 52 kV and power-frequencies from 15 Hz to 60 Hz. La CEI/TR 62271-208:2009 donne des conseils pratiques pour evaluer et documenter les champs electromagnetiques externes generes par des appareillages HT et des postes HT/BT prefabriques. Les exigences de base pour mesurer ou calculer les champs electrique et magnetique sont resumees pour des appareillages couverts par la CEI 62271-200 et la CEI 62271-201 et pour les postes prefabriques couverts par la CEI 62271-202. Ce rapport technique sapplique aux equipements assignes pour des tensions jusqua et y compris 52 kV et des frequences reseau de 15 Hz a 60 Hz.
