SC 14 - Data element principles
To prepare international publications for the interfaces and methods of measurement used with personal computing systems, equipment, and related multimedia products. These publications include specifications and requirements for power and control interfaces, methods of measurement for power consumption and energy efficiency, and interoperability with other systems and equipment
Principes concernant les données-types
La normalisation dans le champ des transformateurs de puissance, des changeurs de prise en charge et des réactances pour une utilisation à la génération de puissance, la transmission et la distribution. Généralement, ces transformateurs ont des puissances assignées supérieures à 1 kVA en monophasé et à 5 kVA en polyphasé et comme plus haute tension dans l’enroulement 1000 V ou plus, cependant le domaine d’application comprend des transformateurs et des régulateurs de moindre tension utilisés pour les applications de distribution de puissance. Sont exclus : - Les transformateurs d’instrument - Les transformateurs d’essai - Les transformateurs de traction montés sur du matériel roulant - Les transformateurs pour souder - Les transformateurs dédiés aux applications couvertes par le TC96.
General Information
Gives insulation requirements for power transformers and the corresponding insulation tests for specific windings. Applies to single-phase and three-phase oil-immersed power transformers as defined in the IEC 60076-1. It Includes appendices on: partial discharge measurements during induced a.c. withstand voltage test on transformers; overvoltage transferred from a high-voltage winding to a low-voltage winding; information to be supplied with enquiries and orders.[

Assists in the selection of tap-changers designed in accordance with IEC 60214-1 for use in conjunction with the tapped windings of transformers or reactors. Also assists in understanding the various types of tap-changers and their associated equipment available. Covers both on-load tap-changers and off-circuit tap-changers.

Identifies the requirements for power transformers to sustain without damage the effects of overcurrents originated by external short circuits. Describes the calculation procedures used to demonstrate the thermal ability of a power transformer to withstand such overcurrents and both the special test and the theoretical evaluation method used to demonstrate the ability to withstand the relevant dynamic effects.

Applies to three-phase and single-phase transformers including autotransformers. Defines the rating and connection symbols. Gives certain specifications for transformers having a tapped winding. Defines information which shall be marked on the rating plate and the tests to be conducted. Supersedes IEC 60076-1(1976) and IEC 60076-4 (1976).[
