IEEE Std 80-2013 is a comprehensive engineering guide that establishes best practices for the design of grounding systems in AC substations. It is primarily concerned with safe grounding practices for AC substations, encompassing both conventional air-insulated substations (AIS) and gas-insulated substations (GIS), at power frequencies in the range of 50 Hz or 60 Hz. The standard applies to a wide range of facilities, including distribution substations, transmission substations, and generating plant substations. With proper caution, the methods described in the standard are also applicable to indoor portions of such substations, or to substations that are wholly indoors.

As noted by Richard Keil, Chair of the IEEE 80 Grounding Working Group, surveys have shown that as many as performing ground-grid design around the world either directly or indirectly rely on IEEE 80. The newest changes to the guide are explicitly intended to enhance users‘ overall knowledge and “provide more detailed information to design a ground grid that applies anywhere in the world.” ieee standard 80-2013 pdf

If the design is not safe, modify the grid (e.g., reduce conductor spacing, add more rods) and re-calculate. How to Access IEEE Standard 80-2013 PDF
Step voltage is the potential difference between two points on the earth's surface separated by a distance of one pace, which is assumed to be 1 meter. A person walking through a substation during a fault can bridge this voltage difference between their feet, causing current to flow up one leg and down the other. 3.

IEEE Standard 80-2013 outlines a structured, 12-step iterative process that engineers must follow to achieve a compliant grounding grid design:
