A critical update involves the handling of switchgear. With the global push to reduce SF6 (Sulfur Hexafluoride) gas due to its high Global Warming Potential (GWP), the 2021 edition adapts design rules to accommodate GIS technologies that use alternative insulation gases (e.g., fluoroketones or compressed air). This includes updated pressure vessel safety guidelines and leak detection requirements.

when standard separation distances cannot be met.

For European users, the CENELEC amendment A11:2025 is particularly important because it aligns the standard with EU directives and adds binding national provisions. Whether you are a power system engineer, a safety manager, or a regulatory officer, IEC 61936‑1:2021 (and its European equivalent) provides the essential rules for ensuring that HV installations are safe, reliable, and compliant. iec 6193612021 link

IEC 61936-1:2021 provides updated international standards for designing and installing power systems over 1 kV AC and 1.5 kV DC, incorporating enhanced safety, fire protection, and harmonized global guidelines. This revision replaces the 2010 version, offering clearer definitions for high-voltage and improved accessibility requirements for personnel. Access the standard through the International Electrotechnical Commission (IEC) Webstore or industry platforms like NFPA LiNK .

Furthermore, it does not apply to the design of , for which separate IEC standards exist. A critical update involves the handling of switchgear

The amendment (published in 2021) is likely what you saw. Some systems concatenate numbers, turning "Part 1 – Amendment 1 - 2021" into a garbled "6193612021".

As shown in the table above, this standard references numerous other documents, including CIGRE Technical Brochures and IEEE Guide 998, creating a comprehensive "web" of resources for the power engineer. when standard separation distances cannot be met

In practical terms, the standard directly guides the engineering and construction of:
