Iec 600995 Pdf

The IEC 60099-5 PDF 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

4. Third Possibility: IEC 60099 (Surge Arresters)

If the application is power system protection (lightning arresters, surge protective devices), the standard is IEC 60099. iec 600995 pdf

The importance of IEC 60099-5

The standard acts as an informative guide (rather than a mandatory test specification) to help engineers choose the correct arrester for specific network conditions. It covers: BSI Knowledge Gapless Metal-Oxide (MO) Arresters : As defined in IEC 60099-4. Gapped Metal-Oxide Designs : Both internally gapped (rated is less than or equal to 52 kV) and externally gapped line arresters (EGLA).
