, titled "Surge arresters - Part 5: Selection and application recommendations," provides comprehensive guidance for the selection and application of surge arresters. While IEC 60099-4 defines the performance requirements and testing methods for metal-oxide surge arresters (without gaps) for AC systems, IEC 60099-5 explains how to apply those products in real-world scenarios.

The 2018 edition features expanded annexes on calculating cumulative charges and energy during line switching 1.2.3. IEC 60099-5 PDF Link: Accessing the Standard iec 600995 pdf link

To accurately design insulation coordination, engineers must evaluate three primary electrical constraints highlighted by the standard:

Its main features include:

The official standard serves as the ultimate international guideline for the selection and application of surge arresters in three-phase power systems operating above 1 kV . Published by the International Electrotechnical Commission (IEC), this document provides utility engineers, substation designers, and asset managers with the mathematical formulas, engineering criteria, and insulation coordination practices required to protect critical high-voltage infrastructure from transient overvoltages.
