Ieee Standard 80-2013 Pdf

IEEE Std 80-2013, "Guide for Safety in AC Substation Grounding," provides technical criteria for designing safe grounding systems to control touch and step voltages, covering soil resistivity and fault current division. This updated standard addresses modern safety concerns and specific challenges in gas-insulated substations (GIS) by utilizing refined equations for grid resistance and safety calculations.

Key Changes in the 2013 Revision (vs. 2000)

C. The Importance of Surface Material

• Step Potential ($U_S$): The voltage difference between a person’s feet when standing near a grounded structure. If this difference is too high, current travels up one leg and down the other, potentially causing fibrillation.
• Touch Potential ($U_T$): The voltage difference between a grounded object (like a fence or switch handle) and the earth a person is standing on. This is generally considered more dangerous because the current path travels hand-to-foot, crossing the heart.

• Purchase Options: You can buy a personal PDF copy directly from IEEE.
• Corporate Access: Most engineering firms and utilities hold organizational licenses.
• University Access: Engineering students often have free access through their university libraries.
