Applies to new inductive voltage transformers for use withelectrical measuring instruments and electrical protective devicesat frequencies from 15 to 100 Hz. This standard relates basically to transformers with separate windings, but also to autotransformers.It replaces IEC 60186 (1987) plus Amendments 1 and 2only for inductive voltage transformers. IEC 60186 remains in forcefor capacitive voltage transformers.This consolidated version consists of the first edition (1997) and its amendment 1 (2000). Therefore, no need to order amendment inaddition to this publication.
