The document’s primary goal is to prevent fatal electric shock under fault conditions. It distinguishes between:
IEEE Guide for Safety in AC Substation Grounding Status: Active Standard (Supersedes IEEE 80-2000) Scope: Provides guidance for the design of AC substation grounding systems to ensure safety against step, touch, and transferred voltages. ieee standard 80-2013 pdf

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. The standard now uses a 50 kg (110
Understanding IEEE Std 80-2013: A Guide to AC Substation Grounding Safety
If you work in electrical engineering, power systems design, or utility safety, you have likely encountered the "Green Book." Officially titled , this document is arguably the most critical reference for ensuring that electrical substations remain safe for personnel and equipment during fault conditions.
