The potential difference between a person’s feet when taking a step, caused by voltage gradients on the ground surface. 2. Tolerable Body Current
Determine the resistance of the proposed grid. ieee standard 80-2013 pdf
The standard does cover grounding problems peculiar to DC substations, nor does it provide a quantitative analysis of the effects of lightning surges, as these are beyond its intended scope. However, for the vast majority of AC power system installations, IEEE Std 80-2013 remains the definitive reference for grounding system design. The potential difference between a person’s feet when
For decades, the global benchmark for designing these life-saving systems has been , titled "IEEE Guide for Safety in AC Substation Grounding." The standard does cover grounding problems peculiar to
The standard calculates the maximum allowable touch and step voltages by determining how much current a human body can handle based on the duration of a fault. 3. Ground Resistance The overall resistance of the ground grid ( Rgcap R sub g
