: Adds new informative annexes (H, I, and J) regarding class transition calculations, switching surge estimations, and guidance on replacing older SiC arresters.

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.

The International Electrotechnical Commission (IEC) framework categorizes surge protection devices (SPDs) and arresters under the IEC 60099 family. While testing obligations for manufacturers are split across distinct documents—such as IEC 60099-4 for gapless metal-oxide surge arresters (MOSA) and IEC 60099-8 for externally gapped line arresters (EGLA)—. Scope of the Standard

Surge arresters with series and parallel gapped structures rated at 52 kV or less (IEC 60099-6). The standard covers various aspects of surge arrester
