Dimensions of toroids made of magnetic oxides or iron powder
Gives information to serve as a guide for the future design of toroids (ring cores) of rectangular cross-section, made of magnetic oxides or iron powder, for pulse and broadband transformers. Toroidal magnetic strip-wound cores form the subject of a separate publication.
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.
Assists the selection of suitable on-load tap-changers for use in conjunction with the tapped windings of transformers or reactors. This publication should be read in conjunction with IEC 60214 and IEC 60076. Gives field service advice concerning safety of operation, parallel operation, contact erosion and oil contamination, also comprehensive details for accompanying enquiries and orders.
Guide d'application pour changeurs de prises en charge
Aide au choix des changeurs de prises en charge convenables destinés à être utilisés avec les enroulements de réglages des transformateurs ou des inductances. Celle publication doit être utilisée avec la CEI 60214, ainsi qu'avec la CEI 60076. Donne des renseignements sur le fonctionnement sur place concernant la sécurité des opérations, la marche en parallèle, l'usure des contacts et la…
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…
Variable capacitors. Part 4: Type specification for variable pre-set capacitors Type C
These three publications give test methods and requirements for judging electrical, mechanical and climatic properties and for a system of classification into categories according to the ability of the capacitors to withstand the conditions specified.
Expression of the properties of cathode-ray oscilloscopes. Part 1: General
Applicable to general-purpose cathode-ray oscilloscopes for measuring electrical quantities. Special definitions. Standard data. Conditions and methods for testing the properties. This publication supersedes IEC 60351 (1971).
Supplement E - Measurement of the electrical properties of microwave tubes - Part 2: General measure...
Gives terms, definitions, basic theory and recommended methods of measurement of the effects of non-linearity in electronic tubes. Although primarily intended for electronic tubes, this publication also applies to other electronic devices.
Complément E - Mesure des caractéristiques électriques des tubes pour hyperfréquences - Deuxième par...
Donne les termes et définitions, la théorie de base et les méthodes de mesure recommandées des effets non linéaires dans les tubes électroniques. Bien que traitant avant tout des tubes électroniques, cette publication s'applique aussi à d'autres dispositifs électroniques.
