IEC 60099-5:2018 (Edition 3.0) is the international standard providing guidance for the selection and application of surge arresters in systems above 1 kV. IEC Webstore Key Deep Feature: Integrated Selection Methodology
The PDF document contains 116 pages of detailed specifications, guidelines, and testing methods for surge arresters. The standard covers various aspects, including: While IEC 60099-5 itself has not been updated
The technical shift introduced in the latest iteration () moves the industry away from obsolete line discharge classifications and establishes an advanced, energy-centric modeling framework. This complete engineering guide covers the core methodologies, calculation parameters, and updates foundational to the IEC 60099-5 PDF standard. Key Technical Scope of IEC 60099-5
IEC 60099-5 is the fifth part of the IEC 60099 series, titled "Surge arresters – Part 5: Selection and application recommendations." Unlike mandatory specifications that dictate exact product characteristics, this standard serves as an essential guidebook. It provides in-depth information, practical guidance, and best-practice recommendations for the correct selection and application of surge arresters in three-phase AC power systems.
