Its main features include:

The current version, , represents a significant update, designed to align with the latest developments in surge arrester technology and revised testing procedures. This version includes updated normative references and comprehensive guidance on the application of metal-oxide surge arresters in high-voltage systems. How to Obtain the IEC 60099-5 PDF Link

: It applies to gapless metal-oxide surge arresters (IEC 60099-4), gapped structures (IEC 60099-6), and external series gap arresters for transmission (IEC 60099-8). Major Updates in Edition 3.0 :

You can access the IEC 60099-5 standard through the following link:

The latest edition () introduced a paradigm shift by completely aligning its selection procedures with the new energy and charge-based classifications established in the product-testing standard, IEC 60099-4. Arrester Technologies Covered iec 600995 pdf link

: The current version is IEC 60099-5:2018 (Edition 3.0) , which replaced the 2013 version to align with updated arrester classifications. Key Topics Covered : Selection criteria for metal-oxide surge arresters (MOSA). Insulation coordination and installation practices.

Other key topics covered in the 190-page document include general application principles, insulation coordination, special applications, and diagnostic indicators for arresters in service.

The standard, officially titled "Surge arresters – Part 5: Selection and application recommendations," serves as the definitive global blueprint for engineering professionals who design, select, and deploy surge protection systems. Operating medium- and high-voltage power networks requires specialized engineering to combat unpredictable overvoltages caused by atmospheric lightning strikes or heavy-load grid switching. This comprehensive standard bridges the gap between raw hardware manufacturing metrics and real-world system reliability. Core Purpose and Scope of IEC 60099-5

The correct designation is likely:

: As strictly defined by testing configurations in IEC 60099-4.

: Covers gapless metal-oxide arresters (IEC 60099-4), gapped structures (IEC 60099-6), and externally gapped line arresters (EGLA, IEC 60099-8).

Could you double-check the standard number? If you meant (the most probable match for "60099x"), it's published in multiple parts covering different domains of electrotechnology.

For engineers and buyers, the next step is to obtain the relevant IEC 60095 parts and incorporate their test‑condition language into specifications and acceptance tests. While the full standard text is sold through national standards bodies (IEC, ANSI, BSI, etc.), summaries and guidance can be found in technical articles and vendor whitepapers that interpret its requirements for real applications. Its main features include: The current version, ,

The document you are looking for is officially designated as IEC 60099-5

provides comprehensive guidance for selecting and applying surge arresters in three-phase systems with nominal voltages above 1 kV. Core Content of IEC 60099-5

: Includes new annexes (Annex H and I) for calculating arrester cumulative charges and energies during line switching. Application Guidance

The standard underwent a profound technical structural shift in its third edition. The core driver was aligning selection guidelines with the fundamental modifications introduced in the hardware standard, which permanently dismantled the long-standing "Line Discharge Class" mechanism. Key Feature / Metric IEC 60099-5:2013 (Second Edition) IEC 60099-5:2018 (Third Edition) Arrester Classification Basis Line Discharge Classes (Class 1 through 5). Thermal Charge ( Qthcap Q sub t h end-sub ) and Repetitive Charge ( Qrscap Q sub r s end-sub Switching Surge Metrics Expressed strictly via kinetic energy calculations ( Calculated through physical charge transfers ( ) during line switching.
