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 ...
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 costs since it halves the amount of wire that is required, with a corresponding saving on the labour ...
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.
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
His lecture exhibited this feature, the chief import exhibited that all kinds of devices could be operated thru a single wire without a wired return. The one-wire transmission system was protected in 1897 by U.S. patent 0,593,138, "Electrical Transformer". This patent diectly deals with this topic. And the text and Tesla's intentions in his one ...
Presidents Eisenhower, Kennedy, Johnson, and Nixon used an Air Force One plane known as SAM 970. The first jet-powered presidential aircraft featured an office and a safe for the nuclear codes.
But as Sheckly continues to press them about losing "Flight 107", Bengston remembers that the only plane the airline ever lost was a Flight 107, 17 or 18 years previously. The case had been investigated by Sheckly but was never solved, the only case he never figured out, closed as "presumed crashed for reasons unknown" at sea.
Jeju Air's chief executive said the airline will reduce its winter air traffic by up to 15 per cent and aim to secure trust following the death of 179 people in the plane crash.
