An engineer using a corrupted free PDF misinterpreted the mesh voltage formula ( E**m ), leading to an undersized grounding grid. During a single-phase fault, the touch voltage exceeded safe limits, causing a fatal accident. The investigation cited “use of unauthorized, incomplete reference documents.”

With proper caution, the methods described can also be applied to the indoor portions of these substations. However, the standard explicitly does cover grounding issues unique to DC substations or provide a quantitative analysis of lightning surge effects, though a system designed per this guide will still offer some protection. Designing a safe substation grounding grid requires a

The standard covers a vast amount of information crucial for substation grounding design. The table of contents below gives you a complete overview of its 226 pages, organized into 20 clauses and 8 informative annexes:

A common mistake is assuming all fault current goes into the grid. The standard provides methods to calculate how much current returns through overhead shield wires and neutral conductors. Use the split factor equations (Sf) to reduce the grid current—this saves thousands in copper costs. This link or copies made by others cannot be deleted

: The standard uses an iterative process to design a mesh of buried conductors (often copper or copper-bonded steel) to create an equipotential plane .
