Understanding IEC 60099-5: The Definitive Guide to Surge Arrester Selection and Application Updates

The (Edition 3.0) is the current international standard providing guidance and recommendations for the selection and application of surge arresters in three-phase systems above 1 kV. As a technical revision of the 2013 edition, it aligns application practices with the modern arrester classification system introduced in IEC 60099-4:2014 . Core Scope and Coverage

The standard provides a comprehensive structural framework optimized for medium-, high-, and extra-high-voltage power networks. Rather than detailing manufacturing processes, it focuses on the operational environment and application requirements.

Identical versions exist as BS EN IEC 60099-5:2018 (UK) or SIST EN IEC 60099-5:2018 (Slovenia/EU).
