Protecting people from electric shocks and arc flash hazards.

High-voltage transformers containing flammable dielectric fluids represent significant fire hazards. The framework outlines fire mitigation practices, including explicit physical segregation barriers, water spray systems, and fluid-containment catchments to shield nearby buildings from thermal propagation.

: Standard grid substations as well as dedicated railway power supply facilities.

: Requirements for GIS (Gas-Insulated Switchgear) and transformer installations have been reintroduced or improved.

Designing a substation or power plant under IEC 61936-1:2021 requires strict adherence to physical and electrical parameters. 1. Insulation and Clearances

Every time you walk past a transformer station in a city, or drive by a high-voltage substation, and you don't hear an explosion or feel a tingle in your feet, you are living in the "happily ever after" written by this standard. It is the silent guardian of the high-voltage age.

The 2021 iteration introduced structural changes to align high-voltage practices with contemporary engineering fields: IEC 61936-1:2021
