Additional, more complex sample calculations were added to assist designers. 5. Summary of Workflow for Using IEEE 80
The primary goal of this standard is to provide guidelines for protecting personnel from electric shock within outdoor AC substations (conventional or gas-insulated). Safe Limits: Pirated files often contain corrupted text, missing appendix
IEEE Std 80-2013 is the bedrock document for AC substation grounding safety. While it is now withdrawn, it remains an indispensable guide for practicing engineers worldwide. By purchasing an official PDF from an authorized distributor like Accuris, you ensure you have a complete, accurate, and legally obtained copy. Understanding its structure—from the tolerable body current limits in Clause 6 to the benchmark cases in Annex H—will empower you to design safer, more reliable substations.

The core variable driving grid design, measured using methods like the Wenner four-pin test. Estimate Grid Resistance
Use standard IEEE equations to calculate the actual mesh voltage ( Emcap E sub m ) and step voltage ( Escap E sub s ) generated by your layout.

The PDF price from an authorized reseller like Accuris is approximately $206.00 USD.
Measure the physical area of the substation and conduct a soil resistivity test. Soil profile testing typically utilizes the Wenner four-pin method to determine if the soil is uniform or multi-layered. 2. Conductor Sizing
Draft a preliminary layout of the grid loop. This includes a perimeter conductor enclosing the area, cross-conductors spaced at regular intervals, and ground rods driven at critical nodes or corners. 5. Estimate Grid Resistance
