This part of IEC 61869 applies to new inductive voltage transformers for use with electrical measuring instruments and electrical protective devices at frequencies from 15 Hz to 100 Hz. Requirements specific to three-phase voltage transformers are not included in this standard but, so far as they are relevant, the requirements in clauses 4 to 10 apply to these transformers and a few references to them are included in those clauses (for example, see 3.1.303, 5.301.1, 5.301.2, 5.5.301, 6.13.301.1 and Table 304). All the transformers shall be suitable for measuring purposes, but, in addition, certain types may be suitable for protection purposes. Transformers for the dual purpose of measurement and protection shall comply with all clauses of this standard. The responsible committee is K 471 "Messwandler" ("Instrument transformers") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
