IEC 61558-2-10:2024
Safety of transformers, reactors, power supply units and combinations thereof - Part 2-10: Particular requirements and tests for separating transformers with high insulation level and separating transformers with output voltages exceeding 1 000 V
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.

IEC 61558-2-10:2014 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 standard. This first edition cancels and replaces Chapter ll Section Three of IEC 60989 published in 1991. It constitutes a technical revision. The main changes consist of a) updating this part in accordance with IEC 61558-1:2005, and b) adding power supply units to the scope. The attention of National Committees is drawn to the fact that equipment manufacturers and testing organizations may need a transitional period following publication of a new, amended or revised IEC publication in which to make products in accordance with the new requirements and to equip themselves for conducting new or revised tests. It is the recommendation of the committee that the content of this publication be adopted for implementation nationally not earlier than 12 months from the date of publication. The transitional period is not longer than 3 years after the publication of this standard. This publication is to be read in conjunction with IEC 61558-1:2005.
The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.
The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
