  2. Single-wire earth return - Wikipedia

    en.wikipedia.org/wiki/Single-wire_earth_return

    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 ...

  3. Earth-return telegraph - Wikipedia

    en.wikipedia.org/wiki/Earth-return_telegraph

    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 ...

  4. Electric power transmission - Wikipedia

    en.wikipedia.org/wiki/Electric_power_transmission

    Single-wire earth return (SWER) or single-wire ground return is a single-wire transmission line for supplying single-phase electrical power to remote areas at low cost. It is principally used for rural electrification, but also finds use for larger isolated loads such as water pumps. Single-wire earth return is also used for HVDC over submarine ...

  5. Earth return - Wikipedia

    en.wikipedia.org/wiki/Earth_return

    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

  6. Transmission line - Wikipedia

    en.wikipedia.org/wiki/Transmission_line

    Cables are similar to twisted pair in that many cores are bundled into the same cable but only one conductor is provided per circuit and there is no twisting. All the circuits on the same route use a common path for the return current (earth return). There is a power transmission version of single-wire earth return in use in many locations.

  7. Single-wire transmission line - Wikipedia

    en.wikipedia.org/wiki/Single-wire_transmission_line

    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.

    With Christmas near, bringing out the boughs of holly now -- even as you may still be putting fall decorations away -- may make you a happier person, experts say. "For most people, decorating for ...

  9. Ground (electricity) - Wikipedia

    en.wikipedia.org/wiki/Ground_(electricity)

    In single-wire earth return (SWER) AC electrical distribution systems, costs are saved by using just a single high voltage conductor for the power grid, while routing the AC return current through the earth. This system is mostly used in rural areas where large earth currents will not otherwise cause hazards.
