Q. Action to be made if the resistance to earth of earth electrode is high?
Ans: Earth resistance lies upon soil conductivity. To reduce earth resistance dig around the earth electrode, clean all the rust around earth pipe or plate. Sprinkle the common salt dissolved water in the pit and pack it up with powdered coke and salt. If it is not possible give additional earths and connects all the earth points in parallel by solid jumper connections.
