Measuring circuit for Fall of Potential test. When wired as shown, one of the Fluke 162x series Earth Ground Testers forces a known current between the outer stake and the Earth electrode, creating a voltage gradient in the soil. The tester then measures the voltage drop between the inner stake and the earth electrode.
WebLeakage Current testing is used to verify that the product does not leak excessive current when contacted by the user. For medical equipment, the current flowing to ground is measured. Excessive leakage current can cause the heart to go into ventricular fibrillation resulting in cardiac arrest which can lead to death.
