) and compare them against the tolerable limits. If the actual voltages exceed the limits, the design must be refined (e.g., by adding more conductors or ground rods). Academia.edu Key Technical Parameters Description Typical Target Value cap R sub g Ground Resistance (large substations); (distribution) Step Voltage Voltage between feet 1m apart Must be less than tolerable cap E sub s t e p end-sub Touch Voltage Voltage between hand and feet Must be less than tolerable cap E sub t o u c h end-sub Grid Depth Burial depth of the mat Common range: 0.5m to 1.5m Official Access & Resources Official Document : You can purchase or access the full text through the IEEE Xplore Digital Library Sample Calculations : For a detailed walkthrough of the math, review Annex B of the standard , which provides complex design examples. IEEE Guide for Safety in AC Substation - Grounding

Are you designing for a or auditing an existing grid ? ieee standard 80-2013 pdf

Defines the limits of tolerable touch and step voltages to protect human beings, based on body weight, soil resistivity, and fault duration.

Note: The official, authorized version of IEEE Standard 80-2013 is a copyrighted document available for purchase and download through the IEEE Xplore Digital Library or authorized standards resellers.

The standard itself is often dense theoretical text, but the annexes are where the practical engineering work happens: Multiply the maximum grid current ( Igcap I

Provides methodology for optimizing grid conductor size, spacing, and burial depth.

The design process recommended in the standard generally follows this sequence:

Without the standard, you would never know the difference until the first fault kills a technician. Academia

Electrical grounding is the backbone of power system safety. Among the various codes and standards governing electrical engineering, IEEE Standard 80-2013 stands as the global benchmark for safety in AC substation grounding. Developed by the IEEE Power and Energy Society, this document provides the analytical tools, design guidelines, and safety criteria necessary to protect human life and equipment from the hazards of high-voltage faults.

If you're looking for practical examples of how to apply the IEEE 80-2013 standard, or have a specific design challenge (like high-resistivity soil), I can help you:

) that a human body can tolerate before entering ventricular fibrillation. The standard provides formulas for two distinct body weights: and 70 kg (154 lbs) . The formula for the tolerable body current is:
