Some notable changes in the 2013 revision include:
Create an initial grid layout and conductor size.
for different types of soil.
Soil resistivity is a fundamental parameter that significantly impacts the performance of a grounding system. IEEE 80-2013 provides detailed procedures for measuring and modeling soil resistivity, including the Wenner four-pin method. Accurate soil data is essential for calculating the resistance of the grounding grid. Ground Grid Design and Analysis
: Transferred potentials occur when a conductor bonded to the substation grounding grid extends outside the substation area (e.g., low-voltage communication lines, rails, or metallic pipelines). A fault inside the substation will project the full GPR down that conductor, presenting an extreme shock hazard to unsuspecting individuals outside the station. Isolation transformers or neutral-blocking devices are necessary to decouple these elements. ieee standard 80-2013 pdf

Key Technical Sections of the PDF 80-2013 - IEEE Guide for Safety in AC Substation Grounding Some notable changes in the 2013 revision include:
Compare the calculated mesh and step voltages against the allowable tolerable limits calculated in Step 3.
Officially titled "IEEE Guide for Safety in AC Substation Grounding," this 2013 revision (often referred to by its nickname, the "Green Book") is the cornerstone of ground grid design. For engineers, students, and safety officers, obtaining and understanding the is a critical task. IEEE 80-2013 provides detailed procedures for measuring and
