  • SF6 Circuit Breaker: What Are They? (Types and Operation

    Oct 23, 2020 · During operation of SF6 circuit breaker, this highly compressed gas is released through the arc in the breaker and collected to a relatively low-pressure reservoir and then it is pumped back to the high-pressure reservoir for reutilizing. The working of SF6 circuit breaker is a little bit different in modern time. The innovation of puffer type design makes the operation of SF6 CB much easier.

  • The Beginnings of American Railroads and Mapping | History of

    Early historyConstructionOriginsFundingRecognitionThe earliest survey map in the United States that shows a commercial \\"tramroad\\" was drawn in Pennsylvania in October 1809 by John Thomson and was entitled \\"Draft Exhibiting . . . the Railroad as Contemplated by Thomas Leiper Esq. From His Stone Saw-Mill and Quarries on Crum Creek to His Landing on Ridley Creek.\\" Thomas Leiper was a wealthy Philadelphia tobacconist and friend of Thomas Jefferson, who owned stone quarries near Chester. Using his survey map, Thomson helped Reading Howell, the project engineer and a well-known mapmaker, construct the first practical wooden tracks for a tramroad. Thomson was a notable land surveyor who earlier had worked with the Holland Land Company. He was the father of the famous civil engineer and longtime president of the Pennsylvania Railroad, John Edgar Thomson, who was himself a mapmaker. In 1873 the younger Thomson donated his father1809 map to the Delaware County Institute of Science to substantiate the claim that the map and Leiperrailroad were the first such work in North America.[2] Soon joining the B & O as operating lines were the Mohawk and Hudson, opened in September 1830, the Saratoga, opened in July 1832, and the South Carolina Canal and Rail Road Company, whose 136 miles of track, completed to Hamburg, constituted, in 1833, the longest steam railroad in the world. The Columbia Railroad of Pennsylvania, completed in 1834, and the Boston and Providence, completed in June 1835, were other early lines. Surveys for, and construction of, tracks for these and other pioneer railroads not only created demands for special mapping but also induced mapmakers to show the progress of surveys and completed lines on general maps and on maps in \\"travelers guides\\". The earliest printed map in the collections of the Library of Congress based on government surveys conducted for a state-owned railroad is \\"Map of the Country Embracing the Various Routes Surveyed for the Western & Atlantic Rail Road of Georgia, 1837\\". The surveys were made under the direction of Lt. Col. Stephen H. Long, chief engineer, who ten years earlier had surveyed the routes for the Baltimore and Ohio[6]. Work on the 138-mile Georgia route from Atlanta to Chattanooga started in 1841, and by 1850 the line was open to traffic. Its strategic location made it a key supply route for the Confederacy. It was on this line that the famous \\"Andrews Raid\\" of April 1862 occurred when Union soldiers disguised as railroad employees captured the locomotive known as the General.[7]
