Fault current ground path
Fault current ground path
(OP)
How come I never see the impedance of the earth in fault current calculations? If you have a fault, doesn't it have to makes its way in the ground back to your ground source or sources? I see stuff associated with creating a low effective fault paths in the NEC but nothing elsewhere for higher voltage stuff like in distribution and transmission. Is earth that great of a conductor for fault currents?
