Given several high-profile fence-related accidents, the 2013 revision includes a dedicated, expanded section on fence grounding. It mandates that chain-link fences located within the zone of influence of a ground grid must be bonded to the grid, and it provides specific equations for touch voltages at fence gates and corners.

The 2013 edition refines the allowable body current based on updated biomedical research. The standard now uses a 50 kg (110 lb) and 70 kg (154 lb) body weight model more accurately. The tolerable step and touch voltages are recalculated using these refined models, generally resulting in slightly more conservative (safer) limits than the 2000 edition for the same fault clearing time. ieee standard 80-2013 pdf
The standard reinforces the importance of a high-resistivity surface layer (crushed rock) on substation surfaces. It provides corrected formulas for the derating factor (Cs) that are easier to apply iteratively. The 2013 version explicitly warns engineers about the reduction in rock resistivity when wet or contaminated. The standard now uses a 50 kg (110
Introduction: The "Green Book" of Grounding In the world of electrical power engineering, safety is not just a priority—it is a mathematical certainty. When designing substations, generating stations, and high-voltage transmission line facilities, one document stands above all others as the definitive guide for ensuring the safety of personnel and the public: IEEE Standard 80-2013 . It provides corrected formulas for the derating factor
