IEEE 3192-2025

This guide describes methods of corrosion inspection and evaluation of high-voltage direct current (HVDC) grounding electrodes, including general requirements, selection of excavation point, excavation, sampling, corrosion inspection, and evaluation. This guide is applicable to corrosion inspection and evaluation of HVDC grounding electrodes after excavation with voltage ratings from ±400 kV to ±1100 kV.

This guide provides a practical reference document to detect and evaluate the corrosion of HVDC grounding electrodes after excavation.
