A well-written, essential standard that excels at "general requirements" but deliberately leaves component-level and advanced analysis to other standards. Keep it on your shelf – but keep its companion standards closer.
Substations contain low-voltage (230/400 V AC) supplies for lighting, heating, and control. The standard only touches on segregation and basic protection. For LV design, you still need IEC 60364 series. A well-written, essential standard that excels at "general
You only work on <1 kV systems, DC traction substations, or fully enclosed factory-assembled switchgear (where the manufacturer already complies with 61936-1 via IEC 62271-200). The standard only touches on segregation and basic
This standard is a fundamental reference for utility and industrial high-voltage (HV) substations up to 220 kV (though principles can apply beyond). This review covers its strengths, limitations, and practical application. Rating: 4/5 (Excellent for its scope, but requires companion standards) This standard is a fundamental reference for utility
IEC 61936-1 is the first line of defense for basic safety and design coordination of HV AC substations. It does not replace detailed equipment standards (IEC 62271 series) or specific installation rules, but it provides the overarching principles. For anyone designing, operating, or maintaining a substation >1 kV AC, this is a mandatory reference. 1. Holistic Safety Approach (The "Common Rules") Unlike equipment-focused standards, 61936-1 covers the entire installation: clearances, earthing, fire protection, access control, and warning signs. The section on protection against electric shock (including touch and step voltages) is particularly well-integrated with IEC 61936-1's own earthing calculations.
