Excellent soil models are the basis of all grounding types and they're created from correct soil resistivity testing. Electrical resistivity of soil can be designed with reduced frequency alternating present where The present is utilized at two areas, and the likely variation is measured among two details where by the https://unique-voice55544.kylieblog.com/33890832/the-smart-trick-of-soil-conductivity-testing-bd-that-no-one-is-discussing
