Electrical power distribution systems are often connected to earth ground to limit the voltage that can appear on distribution circuits. A distribution system insulated from earth ground may attain a high potential due to transient voltages caused by static electricity or accidental contact with higher potential circuits. An earth ground connection of the system dissipates such potentials and limits the rise in voltage of the grounded system. WebMar 1, 2000 · The loop impedance is the sum of all impedances in the faulted circuit, including the supply transformer, the ungrounded conductors, and the grounding circuit. For example, a loop impedance of 1 ohm on a 120-V circuit would allow 120 amp to flow, causing the circuit protector to trip very rapidly.
