Instrument transformers - Current transformersInstrument transformers Part 1: Current transformers Executive summary Requirements for current transformers used in electrical measuring instruments and protective devices. Abstract This part of IEC 60044 applies to newly manufactured current transformers for use with electrical measuring instruments and electrical protective devices at frequencies from 15 100 Hz. Although the requirements relate to transformers with separate windings, they are also
