The IEC 60099 family is composed of several parts, each addressing a specific type or application of surge arrester:

The standard document provides definitive international guidelines for the selection and application of surge arresters in three-phase power systems operating above 1 kV . Officially titled "Surge arresters – Part 5: Selection and application recommendations," the latest version is the Third Edition (2018) , which replaces older iterations to incorporate technical adjustments from IEC 60099-4. High-voltage engineers and utility managers use this document to calculate protective levels, establish insulation coordination, and manage the complete lifecycle of grid-protective assets.
