6 Methods of ground/ earth resistance measurement/Testing

Fall of Potential Method Or 3-Point MethodInduced Frequency Testing Or Clamp-On TestingAttached Rod TechniqueStar-Delta MethodDead Earth Method Or Two Electrode MethodIn order to test the resistance using this method, two test electrodes and an earth resistance tester are required. One of these electrodes is used to inject current into the ground and the other (potential electrode) is used to check the voltage. The current electrode is inserted at a distance from the existing earth electrode to a depth equal toSee more on electricalclassroom sciepublish [PDF]
