Power Transmission Systems
Without power lines, a technocratic landscape is unthinkable. With this web of humanity, the whole world has braided. The transmission line is one of the elements of electrical systems that transmits energy through a current. By the way of transportation,
The construction of power lines is a complex engineering task, which includes the following processes: design, installation, commissioning and maintenance. LEPs are distinguished by the nature of the current: constants and variables. By appointment: distribution,
The first experiment on the formation of power lines was carried out in the XIX century. Russian engineer Fedor Pirotsky in 1874 used rails of iron
In those years, scientists around the world were engaged in the development of various ways of transmitting current over long distances. The most effective system was proposed and created by the Russian inventor Mikhail Dolivo-Dobrovolsky. In 1891, under his leadership, the first three-phase current line was built at a distance of 170 kilometers. The energy losses decreased by a quarter. At the International Electrotechnical Exhibition in Germany, scientists around the world recognized that the problem was solved. In St. Petersburg was opened Electrotechnical Institute, which developed the electrification system in Russia and trained specialists.
Initially, Russia did not have its own industrial base for the electrification of the country - the wires were brought from abroad, and the supports were made from improvised material - wood. During the First World War, the revolution and civil war, the construction of the power line was suspended. And since 1923 the students of Mikhail Dolivo-Dobrovolsky, who stayed in Russia, continued the work of their teacher.
