Defines the limits of tolerable touch and step voltages to protect human beings, based on body weight, soil resistivity, and fault duration.
Refinement of the empirical equations used to calculate mesh and step voltages, adjusting factors like Kmcap K sub m Kicap K sub i to align more closely with computer-aided simulations.
The , titled the " IEEE Guide for Safety in AC Substation Grounding ", is the definitive industry standard for designing safe earthing systems in electrical substations. This fourth edition provides updated methodologies to protect personnel from electric shock during fault conditions by establishing limits for tolerable body currents. Core Purpose and Scope ieee standard 80-2013 pdf
IEEE Std 80-2013, titled “Guide for Safety in AC Substation Grounding,” is a focused technical guide that consolidates best practices, measurement methods, and design criteria for protective grounding of alternating‑current substations. First issued decades earlier and revised through 2013, this edition refines procedures to reduce step, touch, and transfer potentials that threaten personnel and equipment during ground-fault events. The standard is broadly used by utility, industrial, and consulting engineers responsible for substation safety and grounding system design.

were updated to provide accurate adjustments when thin surface layers (like crushed rock) are spread over highly variable underlying multi-layer soils.
). If the GPR is lower than the tolerable touch voltage, the design is automatically safe. If it is higher, detailed mesh and step voltage calculations are required. The standard is broadly used by utility, industrial,
To ensure that a person standing in or around the substation is not exposed to the danger of critical electric shock from step, touch, or mesh voltages during a fault condition.
