In this video series, Copperweld’s Jeff Jordan explores trends, technologies, and challenges to conventional thinking in the field of high voltage grounding conductor selection. Each episode attacks a relatively complex or unfamiliar topic, explaining it in practical terms. In the course of ten episodes, a novel method for quantifying the expected reliability of copper and other grounding conductors is described, as a complement the formula for substation design in IEEE Std 80. The series takes the position that selection based on current carrying capability, alone, ignores the likelihood of the conductor being missing or broken when it is needed, years—or even decades—after installation.
Part 1: What is Grounding
Grounding is the name we give to the protective circuit that conducts lightning and power line faults safely into the wet conductive earth, the ground.
