WebOriginally, the voltages on the wires were positive with respect to earth. This is called negative ground, since the negative side of the battery is grounded to earth. Then engineers discovered that with positive voltage on the copper wires, copper wires age quickly, due to electrolysis. WebIn autos there is no earth ground. When the vehicle sits on rubber tires the entire system has floating electrical system (no ground). Suppose you have a car with the positive post of a 12-volt battery connected to the car body. You can connect a single jumper cable from the negative post (the "hot" terminal) to a metal post driven into the earth.

Why Positive Earth?
Single-wire earth return (SWER) or single-wire ground return is a single-wire transmission line which supplies single-phase electric power from an electrical grid to remote areas at lowest cost. Its distinguishing feature is that the earth (or sometimes a body of water) is used as the return path for the current, to avoid the need for a second wire (or neutral wire) to act as a return path. WebSingle Wire Earth Return (SWER) The Single Earth Wire Return (SWER) is a low cost electrical distribution system. It was developed by New Zealand engineer Lloyd Mandeno in the early 1920s for rural electrification. The system is still used in some areas of New Zealand, such as the King Country where it was nicknamed ‘Mandeno’s clothesline’.
