A low impedance ground path is required in order to limit fault voltage to a safe level. The voltage at the location of a ground fault with respect to the earth can be determined from the fault current and the ground circuit impedance (Fig. 2). For example, with a fault current of 100 amp, a 0.1-ohm ground impedance would produce 10 V at the ...While grounding and bonding might seem like the same thing, they have some very important differences. Electrical bonding is the practice of connecting metallic objects that may be exposed to electrical faults or induced voltages to the grounding conductor. This ensures that in the event of a fault the current will have a low resistance path to ...Transformers Level II Lesson 4: Understanding Transformer Overcurrent Protection (22 Questions; Third Year) 22 terms. logan_hoyt89.
