The is the definitive international guide for the selection and application of surge arresters in three-phase power systems with nominal voltages exceeding 1 kV . Rather than defining product tests (which are handled by IEC 60099-4 ), Part 5 provides engineers with the methodology to choose the right arrester for specific grid conditions. Core Scope of IEC 60099-5

IEC 60099-5 is a part of the IEC 60099 series, which covers surge arresters used in electrical power systems. This specific part provides guidelines for the selection and application of surge arresters.
The final version of any IEC standard is a copyrighted, paid document. There are no legal "free" PDF copies available from official sources. However, the standard is widely available for purchase from several official channels. iec 600995 pdf
) . This shift allows for a more precise mathematical evaluation of the thermal energy an arrester can absorb during switching surges. 4. Insulation Coordination and Protection Margins
