Single-wire earth return
Single wire earth return (SWER) or single wire ground return is a single-wire transmission line which supplies single-phase electrical power from an electrical grid to remote areas at low 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. Single-wire earth return is principally used for rural electrification, but also finds use for larger isolated loads such as water pumps. It is also used for high-voltage DC over submarine power cables. Electric single-phase railway traction, such as light rail uses a very similar system. It uses resistors to earth to reduce hazards from rail voltages, but the primary return currents are through the rails.
