Earth or ground is an important thing in electrical installations. I want to know how to do perfect long lasting earth / ground in our lahore soil. I only know that a bore is carried out near water level , they put coal, salt and Qalmi Shora with a copper plate and copper wire.
I want to know the basic principle, standard practices for an earth / ground which can last decade at-least with sure fault prevention. If anyone Electrical Engineer pls guide us with some diagrams, standards and tip will be appreciated.
