A: As of 2025, IEC 61000-4-30 Edition 3.1 (2021) + Corrigendum 1 (2022). Check the IEC webstore for any newer amendments.

If you are an engineer tasked with selecting a surge arrester, follow this workflow using the standard:

  • Evaluate Stress: Determine the expected lightning and switching surge activity in your network.
  • Insulation Coordination:
  • Check Pressure Relief: Ensure the arrester has a pressure relief class suitable for the available fault current at the installation point.

    • A: No. It is a common typo. Use IEC 61000-4-30 or IEC 62586.

    The IEC 60099-5:2018 (Edition 3.0) standard serves as the primary, updated guide for selecting and applying surge arresters in three-phase systems with nominal voltages above 1 kV. It covers gapless metal-oxide, gapped, and line surge arresters (EGLA), incorporating performance-based ratings such as Qrscap Q sub r s end-sub Qthcap Q sub t h end-sub

    instead of traditional line discharge classifications. For more details, visit IEC Webstore. IEC 60099-5:2018

    As of 2026, IEC 60099-5 Edition 3.0 (2018) remains the current standard, offering guidelines for selecting and applying surge arresters in three-phase systems exceeding 1 kV. This 2018 version, which replaced the 2013 edition, is active and directly aligned with the revised classification system in IEC 60099-4:2014. Key technical updates include:

    Classification Shift: Replaced "line discharge class" with a focus on thermal energy ratings ( Qthcap Q sub t h end-sub Wthcap W sub t h end-sub ) and repetitive charge transfer ratings ( Qrscap Q sub r s end-sub ).

    Updated Guidance: Enhanced formulas for calculating charge and new annexes covering class comparisons (Annex H), energy estimation (Annex I), and SiC arrester replacement (Annex J).
