IEEE Std 80 (IEEE Guide for Safety in AC Substation Grounding) serves as the primary standard for designing safe grounding systems, focusing on limiting step, touch, and transferred potentials to protect personnel. The 2013 revision details procedures for designing equipotential grids based on soil resistivity, fault current, and clearing time. For more details, visit IEEE Xplore Digital Library .
