An Introduction to Grounding Calculations and Why They Are Necessary
This webinar, given by Michael Antonishen, P.E. at TriAxis, a Division of DEA, provides a basic introduction to grounding safety calculations (IEEE 80 step & touch) that are generally performed for medium and high voltage AC power stations or similar facilities. Basic grounding concepts and calculation inputs will be introduced, and the need for this type of modeling and analysis will be discussed. Using software programs to model grounding systems and perform analysis is now standard for all but the simplest grounding designs, and commercially available programs have many uses. We will explain some of the most common uses of fully featured grounding programs and show example results for a simple grid design.
