Tap-changers - Part 1: Performance requirements and test methods
Applies to on-load tap-changers of both resistor and reactor types, off-circuit tap-changers, and their motor drive mechanisms. Applies mainly to tap-changers immersed in transformer oil according to EN 60296 but may also be used for tap-changers with gas insulation or immersed in other insulating liquids.

Changeurs de prises - Partie 1: Prescriptions de performances et méthodes d'essai
S'applique aux changeurs de prises en charge aussi bien de type à résistance qu'à bobine d'inductance, aux changeurs de prises hors circuit et à leurs mécanismes d'entraînement à moteur. S'applique essentiellement aux changeurs de prises immergés dans de l'huile pour transformateur selon la EN 60296, mais peut également être utilisée pour des changeurs de prises à isolation gazeuse ou immergés dans d'autres liquides isolants.
