If a grounding system is poorly designed, GPR can cause fatal electrical currents to pass through the body of anyone standing inside or near the substation. The IEEE 80-2013 standard establishes strict methods to calculate and mitigate these physical shock hazards. It primarily focuses on two types of voltages:
If you need a copy of the full standard (PDF), I can suggest where to obtain it (purchase or library access) or summarize specific clauses, examples, or calculation methods from IEEE 80-2013—tell me which section or example you want.
Since the standard is withdrawn, official PDF copies are . However, some authorized distributors may still have inventory while supplies last. These include:
It offers more accurate formulas for calculating the grid geometric factor ( Kicap K sub i ) and the effective buried depth of the grid.
IEEE Standard 80-2013 is the cornerstone of substation grounding safety, providing comprehensive methods to limit step and touch voltages and protect personnel from electric shock during faults. While the standard has been designated Inactive-Reserved, its content remains authoritative and widely used in engineering practice. Engineers should consider the following : ieee standard 80-2013 pdf
When a fault occurs, current flows into the earth, elevating the ground potential. The standard identifies several critical shock pathways:
Updated recommendations on the role of surface insulation (like gravel) in reducing safety risks. 5. Summary of the Design Procedure

By following IEEE Standard 80-2013, utilities can ensure the safe design, installation, and operation of electrical systems in substations, minimizing risks to personnel and the general public. If a grounding system is poorly designed, GPR
Size the conductor based on the fault current, duration, and material. Grid Layout: Create a mesh design.
Determine the minimum cross-sectional area of the grounding conductor based on the maximum symmetrical fault current, fault duration, and material constants (typically copper or copper-clad steel).
Because IEEE standards are intellectual property protected by copyright laws, official copies of the IEEE Standard 80-2013 PDF must be sourced legally through official repositories.
Compare the actual voltages against the tolerable limits. If actual voltages exceed tolerable thresholds, modify the grid geometry (e.g., reduce conductor spacing, add more ground rods) and repeat the calculations. Software vs. Manual Calculations Since the standard is withdrawn, official PDF copies are
The standard covers the following key aspects:
The 2013 version introduced several critical updates over previous iterations (such as the 2000 edition), making the PDF document indispensable for modern engineering:
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.
Calculate the actual expected mesh and step voltages for the initial layout.
Compare the calculated mesh and step voltages against the allowable tolerable limits calculated in Step 3.
