What is Resistance to Ground Measurement? (Part 2)

In this episode, E&S Grounding Solutions President David Stockin concludes a two-part series on resistance to ground measurements by discussing the induced frequency test, often called the “Clamp-On Method." In this method, a comparison is made between an induced current and a return current, while the test voltage is held constant. When the meter is clamped on to an electrode that is in series with a massive resistance loop with many parallel resistances, the meter can display a re...
