WebWhat are Earth Rods? Types and Usage. Earth rod is a rod composed of elements that conduct electricity used in earthing systems. Any incidence of electrical surge can pose dangers of electrocution, especially during lightning. To prevent this, Earth Rod is installed into the ground so that any excess current drifts towards the earth. WebEarthing is defined as “the process in which the instantaneous discharge of the electrical energy takes place by transferring charges directly to the earth through low resistance …
