WebReally good earth connections such as in a district substation are usually less than 5ohm and as such are excellent return paths. From your house, the return path is back to the star (earthed) point on your service transformer, either via the earth or neutral wire depending on the earthing arrangement in your area. Web19 dec. 2024 · Because the supply neutral is bonded to earth in a PME system, the fault return path for both line to earth and line to neutral faults is via the combined conductor. The advantage of using the combined conductor in this way is that it provides a low impedance return path which ensures rapid disconnection of the supply under fault conditions. memphis tenn police beating
