Why is the measurement prior to earthing system essential?

It is essential that all appliances and electrical systems be earthed carefully to avoid any shocks. In this regard, measurement prior to earthing system is essential for the safety of the equipment as well as the people living in the home and area. The measurement must be first done when the electrode is installed the first time. Thereafter, it must be checked and measured at regular intervals. Checking on a regular basis ensures that the resistance to ground does not increase over time. The two methods of testing the electrical grounding system are 3-point or Fall-of-potential method and the second is the clamp-on method.
