Scope

Clause 1 of IEC 61869-1:2023 is replaced by the following:

This part of IEC 61869 applies to newly manufactured inductive voltage transformers intended for applications where the nominal voltage is higher than 1 kV AC for use with electrical measuring instruments and electrical protective devices at rated frequencies from 15 Hz to 400 Hz.

The requirements for inductive voltage transformers for applications in LV systems (nominal voltage ≤ 1 kV AC) are covered by the standard IEC 61869-203.

NOTE 301 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.

All voltage transformers shall be suitable for measurement applications, but in addition certain types may be suitable for protection applications. Voltage transformers for dual application of measurement and protection shall comply with all clauses of this standard.
