The safety and reliability of high-voltage power systems are paramount for modern society. IEC 61936-1:2021 provides the "common rules" for the design and erection of electrical power installations, serving as the primary reference for engineers, utilities, and regulators.

In your technical specification, write: ”The substation shall be designed and erected in accordance with . All clearances, earthing, and safety distances shall meet or exceed Clause 6 and Clause 9 requirements.”

IEC 61936-1:2021 provides updated international standards for designing and erecting AC high-voltage power installations exceeding 1 kV, emphasizing safety for personnel and property. This version includes major technical enhancements regarding gas-insulated switchgear, HVAC requirements, and improved accessibility standards, often implemented as EN IEC 61936-1:2021 in Europe. The full standard is available for purchase on the IEC Webstore . IEC 61936-1:2021

The IEC 61936-1:2021 is a mandatory reference for anyone involved in high-voltage infrastructure. By following the IEC 61936-1:2021 link to obtain a legal copy, you ensure that your projects meet the highest global safety standards, protecting both your workforce and your investment. To help you apply these standards to your specific project:

New requirements for labeling were added for situations where multiple power sources must be disconnected to ensure safety. Gas-Insulated Switchgear (GIS):
