This question may seem trivial but could someone confirm my reasoning? In a 3 phase wye-connected system, with voltages at 120/208v, and feeding a 'balanced' 3 phase 'purely resistive'load, the power can be calculated by summing the power from each phase winding of the transformer.
ie. P_total...
I'm wondering what the mechanism is for fault current traveling into the earth via a grounding electrode from the grounding conductor in a system. Is the current set up due to a potential difference, hence traveling back to it's source via the earth? Or is it more like lightning, where the...
