This part of IEC 60044 applies to newly manufactured current transformers for use with electrical measuring instruments and electrical protective devices at frequencies from 15 Hz to 100 Hz. Although the requirements relate basically to transformers with separate windings, they are also applicable, where appropriate to autotransformers.
