Transformers and inductors for use in electronic and telecommunication equipment - Measuring methods and test procedures
IEC 61007:2020 describes a number of tests for use in determining the significant parameters and performance characteristics of transformers and inductors for use in electronics and telecommunication equipment. These test methods are designed primarily for transformers and inductors used in all types of electronics applications that can be involved in any specification for such components. Even though these tests can be useful to the other types of transformers used in power distribution applications in utilities, industry, and others, the tests discussed in this document can supplement or complement the tests but are not intended to replace the tests in standards for transformers. Some of the tests described are intended for qualifying a product for a specific application, while others are test practices used for manufacturing and customer acceptance testing. The test methods described here include those parameters most commonly used in the electronics transformer and inductor industry: electric strength, resistance, power loss, inductance, impedance, balance, transformation ratio and many others used less frequently. This edition includes the following significant technical changes with respect to the previous edition: a) scope: the application of the scope of IEC 61007 was extended; b) Clause 2: added new references and updated the references; c) Clause 3: new definitions were added in 3.3, and in 3.7 the voltage-time product was redefined; d) test procedures were updated; e) environmental test procedures: new references were added; f) Annexes A to G were added.

Transformateurs et inductances utilisés dans les équipements électroniques et de télécommunications - Méthodes de mesure et procédures d'essais
L'IEC 61007:2020 décrit plusieurs essais utilisés pour la détermination des paramètres importants et des caractéristiques de fonctionnement des transformateurs et inductances utilisés dans les équipements électroniques et de télécommunications. Ces méthodes d'essai sont principalement conçues pour les transformateurs et inductances utilisés dans tous les types d'applications électroniques qui peuvent être employés dans toute spécification de ces composants. Bien que ces essais puissent être utiles pour d'autres types de transformateurs utilisés dans les applications de distribution de puissance dans les services publics, dans l'industrie et d'autres secteurs, les essais traités dans le présent document peuvent s'ajouter aux essais décrits dans les normes relatives aux transformateurs ou les compléter, mais ne sont pas destinés à les remplacer. Certains des essais décrits visent à qualifier un produit pour une application spécifique, tandis que d'autres sont des pratiques d'essai utilisées lors de la fabrication et pour les essais d'acceptation client. Les méthodes d'essai décrites ici comprennent les paramètres les plus couramment utilisés dans l'industrie des transformateurs et inductances électroniques: rigidité diélectrique, résistance, perte de puissance, inductance, impédance, équilibre, rapport de transformation, et de nombreux autres paramètres utilisés moins fréquemment. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) domaine d'application: extension du domaine d'application de l'IEC 61007; b) Article 2: ajout de nouvelles références et mise à jour des références; c) Article 3: ajout de nouvelles définitions en 3.3, et redéfinition du produit tension-temps en 3.7; d) mise à jour des procédures d'essai; e) procédures d'essais d'environnement: ajout de nouvelles références; f) ajout des Annexes A à G.
