    Abstract - (Show below) - (Hide below)

    Applies to newly manufactured current transformers for use withelectrical measuring instruments and electrical protective devicesat frequencies from 15 Hz to 100 Hz. Applies basically totransformers with separate windings, but also to autotransformers.This consolidated version consists of the first edition (1996),its amendment 1 (2000) and its amendment 2 (2002). Therefore, no need to order amendments in addition to this publication.
