WebSoil Resistivity Data. As discussed in the Soil Resistivity and Field Testing article, those analyzing grounding systems are primarily concerned with the soil resistivity typically expressed in Ω-m.Soil resistivity measurements at several locations within the site, or as close as possible, are necessary due to the significant variation of resistivity. WebLearn the common mistakes to avoid so that your project, your tests, are technically secure when they fall under the spotlight of close scrutiny. Webinar Outcomes The key takeaway from this webinar is that you will learn why soil resistivity testing is so massively important to a technically secure earthing design that follows.
