Electronic voltage transformer detection

Scope

This section is applicable to newly manufactured electronic voltage transformers with analog output, used for electrical measuring instruments and protective devices with frequencies ranging from 15Hz to 100Hz Note 1: Optical devices typically include electronic devices, therefore they are considered within the scope of application of this part Note 2: The technical information of electronic voltage transformers is detailed in Appendix C

Note 3: This section does not include requirements specific to three-phase voltage transformers, but they are related. The requirements of Chapters 3-11 apply to these transformers.

Some provisions also include the content of three-phase voltage transformers (such as 2.1.5, 5.1.1, 5.2, 11.2.1, and 11.2.2).
