摘      要：This part of International Standard IEC 60044 applies to newly manufactured electronic voltage transformers with analogue output, for use with electrical measuring instruments and electrical protective devices at frequencies from 15 Hz to 100 *** 1 Optical arrangements usually include electronic components and are therefore considered to be within the application of this *** 2 Detailed information is given in annex BNOTE 3 Requirements specific to three-phase voltage transformers are not included in this standard but, so far as they are relevant, the requirements in clauses 3 to 11 apply to these transformers and a few references to them are included in those clauses (e.g.. see 2.1.5, 5.1.1, 5.2, 11.2.1 and 11.2.2).
