): The voltage difference between a person's feet, separated by a distance of one meter, when walking near a grounded object under fault conditions.

The primary platform for individuals and institutions to purchase, download, and license the official PDF.

Compare the actual calculated voltages against the tolerable thresholds calculated in Step 3.

Determine the minimum cross-sectional area of the grounding grid conductors (typically copper or copper-clad steel) using the standard’s thermal capacity formulas to ensure they do not melt under fault conditions. ieee standard 80-2013 pdf

Before designing, you must collect data on the substation area, such as soil resistivity (often done via Wenner four-pin method), fault current levels, and soil surface layer materials (like gravel). 2. Design of the Grounding Grid

The standard covers the following key aspects:

The , officially titled the " IEEE Guide for Safety in AC Substation Grounding ," is the primary global benchmark for designing safe grounding systems in outdoor AC substations. This version is a significant update that refines the mathematical models used to protect personnel from electric shock during fault conditions. Core Objectives of IEEE 80-2013 ): The voltage difference between a person's feet,

The standard provides that can flow through various types and sizes of conductors for a given duration before failure due to fusing occurs, which is essential for sizing ground grid conductors appropriately.

Estimate the total electrical resistance of the grounding grid to remote earth.

: Defining the maximum tolerable "touch" and "step" voltages a human body can survive. Determine the minimum cross-sectional area of the grounding

As a technical standard, IEEE 80-2013 is a copyrighted document. There are several ways to access it legitimately:

) is significantly higher than the parallel resistance path of feet under touch voltage conditions (
