Scope

<!-- NEW! -->IEC 61558-2-10:2024 is available as <a href="https://webstore.iec.ch/publication/95759">IEC 61558-2-10:2024 RLV</a> which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.



IEC 61558-2-10:2024 deals with the safety of separating transformers with high insulation level and separating transformers with output voltages exceeding 1 000 V. Transformers incorporating electronic circuits are also covered by this document. This second edition cancels and replaces the first edition published in 2014. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:

a) adjustment of structure and references in accordance with IEC 61558-1:2017;

b) overvoltage categories I, II, III and IV for clearances and dielectric strength tests are included;

c) clearances for homogenous field conditions deleted.

It has the status of a group safety publication in accordance with IEC Guide 104.
