Applies to new inductive voltage transformers for use with electrical measuring instruments and electrical protective devices at frequencies from 15 to 100 Hz. This standard relates basically to transformers with separate windings, but also to autotransformers. It replaces HD 554(92) plus Amendments 1 and 2 only for inductive voltage transformers. HD 554 remains in force for capacitive voltage transformers.
