3 phase power calcs.
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.

grounding
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...- gord99
