Dimensions des tores constitués d'oxydes magnétiques ou de poudre de fer
Donne des renseignements destinés à orienter la future conception de tores de section rectangulaire, constitués d'oxydes magnétiques ou de poudre de fer, pour les transformateurs à large bande ou les transformateurs d'impulsions. Les tores à enroulement de rubans magnétiques font l'objet d'une publication séparée.
Class 0.5, 1 and 2 alternating-current watt-hour meters
Applies only to newly manufactured induction type watt-hour meters of accuracy classes 0.5, 1 and 2, for the measurement of alternating current electrical active energy of a frequency in the range 45 Hz to 65 Hz and to their type tests only.
This publication supersedes IEC 43 (1960), 170 (1964) and 280 (1968).
Stabilized power supplies, d.c. output - Part 3: Radio-frequency interference tests
Specifies the measuring equipment and techniques to be used in assessing the conducted electromagnetic interference (EMI) generated by stabilized power supplies and especially by switched-mode power supplies. Relates mainly to power supplies for which the source current required does not exceed 25 A. The techniques employed follow the general principles given in CISPR publications. Requirements…
