The standard is a copyrighted document published by the IEEE Standards Association . : Updated derating factor curves for surface materials
. It focuses on protecting personnel by establishing safety limits for potential differences (voltages) that can occur during a fault 1. Report Overview It focuses on protecting personnel by establishing safety
: It now includes benchmark cases to help engineers verify that their commercial software (e.g., ETAP, CDEGS) aligns with the standard's analytical methods. How to Access the PDF Work
For global projects, note that is dominant in the Americas; IEC 61936 + EN 50522 are preferred in Europe. The IEEE guide assumes 60 Hz (US) but is adaptable to 50 Hz.
The 2013 revision (which incorporates the 2015 corrigendum) introduced several refinements over previous versions:
