Among the technological applications, it is possible to mention shock-condenser welding, metal processing, stamping, riveting, assembly and forming operations, etc. LIECs are used for various testing systems for impact loads, high-speed electrical devices, destruction of information in the event of unauthorized access, valve-switching equipment, seismic sources, cleaning of bunkers from remaining materials and power lines from icing, launchers, etc. Many types of inductive current limiters in the form of reactors are used to limit short-circuit currents, maintain bus voltage, and some other purposes. According to their purpose, they are divided into current-limiting reactors that smooth out communication barriers (for example, in electrified railway networks), starters for synchronous compensators, etc. in the step-down transformer circuit of power stations and substations. Low structural reliability of overhead lines due to the formation of ice on wires and lightning protection cables. Visual inspections of high-voltage power lines remain the main way of diagnosing icy deposits, and it is also necessary to consider equipping overhead lines with telemetry devices. The use of an autonomous asynchronous generator (AG) with a short-circuited rotor in autonomous power sources is considered. According to the proposed excitation scheme with one capacitor, which is switched on between the phases of the stator winding, the performance of the AG in the nominal mode of operation under laboratory conditions is investigated, with the measurement of the active power, and methods of regulating the active power of the AG are also considered, the analytical expression for the active power using the parameters of the AG is obtained. The current state of the coatings was studied. Product Description popup.authors Boliukh Volodymyr F. Honcharov Yevhen V. Kocherha Oleksandr I. Kriukova Nataliia V. Markov Vladyslav S.
