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. 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 ...
Part of the Russian–American Telegraph line bearing the single wire of an earth-return circuit, c. 1866. Earth-return telegraph is the system whereby the return path for the electric current of a telegraph circuit is provided by connection to the earth through an earth electrode. Using earth return saves a great deal of money on installation ...
Earth return or ground return is an electric circuit using the earth for one conductor. It may refer to: Earth-return telegraph; Single-wire earth return, an electric power distribution system; Simplex signaling, an earth return signalling system used in telephony
Important examples of these single-wire systems were the Morse telegraph (1837) and the Cooke & Wheatstone single-needle telegraph (1843). In such systems the cost of a return conductor was fully 50 per cent of the cable costs. It was discovered that a return conductor could be replaced with a return path through the Earth using grounding ...
The single-wire transmission line is not the same as the single-wire earth return system, which is not covered in this article. The latter system relies on a return current through the ground, using the earth as a second conductor between ground terminal electrodes. In a single-wire transmission line there is no second conductor of any form.
I suspect that there is a neutral return wire for this image - you can see a wire running up the pole seperate from the wire to the bushing. Quite common when the economics of the network require SWER but the earth return is not of a high quality ie sandy soil, hard rock etc. Lumberjack Steve 23:14, 18 July 2006 (UTC)
