The 2018 edition is a comprehensive document, containing of detailed information and is priced at CHF 475.00 from the IEC Webstore. Its table of contents is structured to guide the user through the entire process of surge arrester deployment: The standard, officially titled "Surge arresters – Part

For high-voltage transmission systems, arresters are classified by "Line Discharge Classes" (Class 1 through 5).

. Officially designated by the International Electrotechnical Commission as Surge arresters – Part 5: Selection and application recommendations , this document plays an indispensable role in industrial insulation coordination. It bridges the technical testing benchmarks established in manufacturing standards with the real-world operational environments managed by power utility engineers and electrical designers.
