IEEE 80-2013 serves as the essential guide for safe grounding practices in outdoor alternating-current (AC) substations, covering conventional air-insulated and gas-insulated (GIS) substations. Its scope includes distribution, transmission, and generating plant substations. With proper caution, the methods described are also applicable to indoor portions of these substations or wholly indoor substations. The standard is confined to power frequencies of 50 Hz or 60 Hz; problems unique to DC substations and quantitative analysis of lightning surges are beyond its scope.

IEEE Std 80-2013 is a substantial document, comprising of technical content. The standard is organized into the following major sections:

A version is available that shows content and formatting changes between IEEE Std 80-2013 and the previous edition (80-2000). This version includes both the current edition and the redlined document marked with additions and deletions, making it particularly useful for those familiar with the previous version.

IEEE Standard 80-2013, the Guide for Safety in AC Substation Grounding, provides essential guidelines to protect personnel from dangerous step and touch voltages by managing ground potential rise. The standard focuses on designing effective grounding grids, rod placements, and surfacing to maintain safe electrical resistance levels, often recommending 5.0 ohms or less.

The remains a definitive guide for power system engineers globally. Designing a substation grounding system requires strict adherence to its rigorous mathematical principles, precise field soil profiling, and a deep appreciation for human physiological safety limits. By systematically determining soil properties, calculating exact tolerable touch and step voltages, adjusting for fault current distribution, and utilizing advanced software verification when necessary, engineers can construct highly reliable and intrinsically safe power assets.
