Feb 28, 2012· OK hopefully it is now apparent why you should not have your grounding systems isolated, and why the Electrical Code requires all the various grounding systems to be bonded together. It is to have a planned path to limit the voltage difference. Otherwise all the systems come together inside you shack.
The role of the substation is to step it down to lower voltages so it can be safely transmitted to homes and buildings. Relays. The relays are what step voltage up and down between the powerhouse, substation and buildings receiving electricity. They are complex pieces of electrical equipment that require maintenance and careful operation.
This is quantified by the soil thermal resistivity (or thermal rho, °Ccm/W), which can vary from 30 to 500°Ccm/W. Electrical engineers understand the performance of the cable quite well, but to most, the soil behavior is a mystery, usually handled by using a thermal backfill with .
