IEC 60099-5 is a standard published by the International Electrotechnical Commission (IEC) that deals with "Surge arresters - Part 5: Selection and application recommendations".
Here's a brief guide to get you started:
What is IEC 60099-5?
IEC 60099-5 provides guidelines for the selection and application of surge arresters (SAs) used to protect electrical power systems from overvoltages caused by lightning or switching operations.
Scope of the standard
The standard covers the following aspects: IEC 60099-5 standard, specifically the latest 2018 edition
Key topics in IEC 60099-5
Some key topics covered in the standard include:
Why is IEC 60099-5 important?
IEC 60099-5 is important because it provides a framework for ensuring the safe and effective use of surge arresters in electrical power systems. Surge arresters play a critical role in protecting equipment and personnel from overvoltages, and their proper selection and application are essential for reliable system operation.

IEC 60099-5 is Part 5 of the IEC 60099 series of international standards. While other parts of the series (like Part 4) focus on the testing and manufacturing specifications of surge arresters, Part 5 is the application guide.
Published by the International Electrotechnical Commission (IEC), this standard provides recommendations and guidelines for users (utilities, engineers, contractors) on how to select the correct surge arrester for a specific electrical system and how to apply it effectively to protect equipment from overvoltages.
Current Status: The standard has evolved. The most widely referenced version is IEC 60099-5:2018 (Edition 3.0). This edition replaced the 2000 version and its amendment, incorporating significant changes regarding high-voltage arresters and modern Metal-Oxide (MO) technology.
Many manufacturers (e.g., Siemens, ABB, Eaton, Hitachi Energy) publish free application notes that summarize the key selection criteria from IEC 60099-5. While not a substitute for the full standard, these can answer 70% of routine questions.
