Many engineering firms, utilities, and universities maintain enterprise subscriptions to IEEE Xplore, allowing employees and students to download the standard at no personal cost.
is the latest revision (as of the publication of this article) of the iconic "Green Book" for substation grounding. First published in 1961 and revised several times since (including the landmark 2000 edition and the 2013 update), this standard provides practical computational methods and safety criteria for grounding alternating current (AC) substations.

The foundation of a good ground grid is understanding the resistivity of the soil. IEEE 80-2013 emphasizes that soil is not uniform and recommends methods like the Wenner four-pin method to analyze the electrical characteristics of the earth. 3.2. Ground Grid Design Parameters The grid design is a collaborative effort, involving: ieee standard 80-2013 pdf

One of the most significant enhancements introduced in the 2013 revision is the presentation of more detailed information on the methods used to determine the current value to be used in the guide’s design equations. The standard also presents new equations for determining the current capabilities of that can be used in grounding grids. This is particularly important for applications where corrosion resistance or specific conductivity requirements necessitate the use of dissimilar metals in the grounding system.

The is the premier global benchmark for designing safe grounding systems in alternating current (AC) electric power substations. Grounding is a foundational pillar of electrical engineering, serving to protect human life, preserve multimillion-dollar equipment, and ensure network reliability. Substation environments are inherently high-risk zones due to potential lightning strikes, line-to-ground short circuits, and transient surges. Without a robustly designed grounding grid, these faults can elevate localized ground potentials to lethal levels. Without a robustly designed grounding grid
