IEC 60099-5 is a standard that specifies the requirements for surge arresters used to protect electrical power systems from overvoltages caused by lightning, switching operations, or other external factors. Surge arresters are critical components in power systems, as they help prevent damage to equipment and ensure the reliability of the electrical infrastructure. The standard covers various aspects of surge arrester design, testing, and application, including materials, construction, and performance requirements.

To help users see what has changed between editions, the IEC now offers a for many standards. The IEC 60095-1:2018 RLV contains the official standard alongside a version where all changes from the previous edition are highlighted in red, providing a quick and easy way to see the technical revisions.
Improved methodologies for determining arrester behavior under severe environmental and heavy pollution conditions. The standard covers various aspects of surge arrester
Engineers must estimate the cumulative electrical charge injected during high-voltage switching surges and lightning strikes. The standard outlines mathematical modeling procedures to calculate thermal stress, ensuring that the selected arrester block does not suffer localized thermal runaway or physical structural cracking from overheating. IEC 60099-5:2018
The scope of the standard is focused on systems with nominal voltages above 1 kV. It is designed to be used alongside several other key standards in the series, including:
used for lightning flashover prevention on overhead transmission lines as defined by IEC 60099-8.
The standard introduces specialized annexes (Annex H and Annex I) featuring detailed mathematical models. These formulas enable engineers to calculate and estimate cumulative charges and energy stresses sustained by arresters during severe grid operations, such as long-distance transmission line switching. 3.
