Research of the strain-deformed state of a bimetallic cylinder liner by the shell method

The characteristic of system-generated overvoltage in the distribution power grid 6-10 kV of industrial enterprises has been given. The problematical character of the determination of the unified approach with the selection of the neutral grounding condition based on the example of the power supply drawing of Severonickel metallurgical combine has been shown. The calculated values of the single-phase ground short currents in the combine network 10 kV for the normal and repair regimes have been given. Some technical measures for a change in the neutral grounding mode of the subdivided sections to compensate the capacitive ground short currents and to limit the overvoltage levels have been proposed.
