: [ E_step = \fracR_b + 2R_fR_b \cdot I_b ] (where ( R_b ) = body resistance, ( R_f ) = footing resistance)

: Provides a quantitative basis for determining tolerable limits for "touch" and "step" voltages.

7.1 Conductor material and corrosion 7.2 Thermal capacity 7.3 Mechanical strength 7.4 Conductor size calculations (based on fusion temperature)

11.1 Alternative methods (deep-driven rods, counterpoise, chemical rods) 11.2 Surface layer improvements ieee std 80 2013

This standard is the definitive guide for designing substation grounding systems to protect personnel from electric shock hazards.

: The potential difference experienced by a person bridging a 1-meter distance with their feet while walking on the earth's surface.

(simplified for crushed rock): [ E_touch = (1000 + 1.5 \cdot C_s \cdot \rho_s) \cdot \frac0.116\sqrtt_s ] (for 50 kg body; ( t_s ) = fault duration, ( \rho_s ) = surface layer resistivity, ( C_s ) = reduction factor) : [ E_step = \fracR_b + 2R_fR_b \cdot

: The primary goal of this standard is to ensure public safety around electrical power lines and substations, focusing on preventing electrical shock hazards.

: It covers safety considerations for persons in the vicinity of electrical power lines, including minimum distances that should be maintained from power lines for safety. (simplified for crushed rock): [ E_touch = (1000 + 1

: Includes transmission, distribution, and generating plant substations, whether air-insulated or gas-insulated.

: Includes the use of high-resistivity surface materials (like crushed rock) to increase the tolerable touch and step voltages for personnel. Design Refinement Methods

This fourth edition (incorporating Corrigendum 1-2015) introduced several refinements over the previous 2000 version: 80-2013 - IEEE Guide for Safety in AC Substation Grounding
