IEC 61000-4-7-ed.2.0

Anotácia textu normy IEC 61000-4-7-ed.2.0 :

Applies to instrumentation intended for measuring spectral components in the frequency range up to 9 kHz which are superimposed on the fundamental of the power supply systems at 50 Hz and 60 Hz. For practical considerations, this standard distinguishes between harmonics, interharmonics and other components above the harmonic frequency range, up to 9 kHz. Defines the measurement instrumentation intended for testing individual items of equipment in accordance with emission limits given in certain standards (for example, harmonic current limits as given in IEC 61000-3-2) as well as for the measurement of harmonic currents and voltages in actual supply systems. The contents of the corrigendum of July 2004 have been included in this copy. Sapplique a linstrumentation destinee a mesurer les composantes spectrales dans la gamme de frequence allant jusqua 9 kHz, qui se superposent au fondamental des reseaux dalimentation a 50 Hz et 60 Hz. Pour des raisons pratiques, la presente norme etablit une distinction entre les harmoniques, les interharmoniques et les composantes au-dela de la plage de frequence harmonique, jusqua 9 kHz. Definit linstrumentation de mesure destinee aux essais dappareils individuels conformement aux limites demission donnees dans certaines normes (par exemple, les limites de courant harmonique donnees dans la CEI 61000-3-2) ainsi qua la mesure des courants et tensions harmoniques sur les reseaux dalimentation eux-memes. Le contenu du corrigendum de juillet 2004 a ete pris en consideration dans cet exemplaire.
