The standard provides specific guidance on earthing metal fences around substations. For example, it suggests installing a supplementary horizontal earth electrode connected to the fence at a distance of approximately 1 meter to reduce touch voltage. Protection Against Fire and External Hazards

IEC 61936 requires that equipment be selected not just for its electrical rating (voltage/current), but for its environmental context. iec 61936

Specifically titled “Power installations exceeding 1 kV a.c.” , this standard is the backbone of safety and design for power plants, substations, and heavy industrial infrastructure. The standard provides specific guidance on earthing metal

Designers must account for seismic activity, vibration, and even the effects of local wildlife or micro-organisms on the installation's integrity. 3. Operational Safety and Accessibility iec 61936
