Unlike other parts focusing on testing, this standard acts as a guide for system design. Core Scope and Coverage The standard addresses various technologies: Gapless Metal-Oxide (MO) Arresters: Covered under IEC 60099-4 Gapped Structures: Specific to units with series/parallel gaps (52 kV and below), referenced in IEC 60099-6. Externally Gapped Line Arresters (EGLA): Used in distribution and transmission lines, detailed in IEC 60099-8. Key Technical Updates in Edition 3.0 (2018) Replacing the 2013 version, the 2018 edition includes: Updated Classification: Selection methods aligned with the 2014 revisions in IEC 60099-4. Charge Classification: Enhanced focus on transitioning to new charge classifications, including methods for estimating stress. Energy Estimation: New annexes for calculating energy and cumulative charge during switching. Selection and Application Criteria Key factors for design include: IEC 60099-5 Ed. 3.0 en:2018 - Surge arresters - ANSI Webstore
The search results suggest "IEC 600995" is likely a typo for IEC 60099-5 , which is the international standard for the selection and application of surge arresters in power systems. Standard Overview: IEC 60099-5 This standard provides critical guidance for engineers and manufacturers on how to choose and coordinate surge arresters for three-phase systems with voltages above 1 kV. Latest Edition : The current version is IEC 60099-5:2018 (Edition 3.0) , which replaced the 2013 version to align with updated arrester classifications. Key Topics Covered : Selection criteria for metal-oxide surge arresters (MOSA). Insulation coordination and installation practices. Asset management, diagnostic tools, and end-of-life strategies. Target Users : Utility engineers, substation designers, and maintenance teams. Official PDF Links & Sources Since IEC standards are copyrighted, official full versions are typically paid documents.
