Can anyone guide in calculating grounding for a 40 ft tower for camera? We will be installing a lighting rod and tie into the ground rod. Each leg of the tower will be CAD weld and tied into the ground rod. Wenner test is pending to get the soil resistivity.
Questions here are :
1) calculating the earth grid conductor sizing?
Should I use the equation 37 on IEEE 80 greenbook to calculate it?
2) How do you calculate number of ground rods required in order to get 5Ohms once we have the soil resistivity?
3) Do I need to calculate touch and step potential since there is no electrical generation beside the lighting rod?
