TL;DR: In this paper, the authors studied the working intensity of the electrical field in the cast epoxy insulation of a 6- to 110-kV switchgear taking into account its dimensions, structure, and basic operational factors.

TL;DR: In this paper, the authors describe the use of high-voltage busbar (current carrier) designs to connect various objects in stations and substations (generators, transformers, switchgear, etc.) and individual components of these systems (e.g., switchgear cells).

TL;DR: The use of rigid noncorona busbars with the air insulation, gas-filled current leads, and current leads with the polymeric insulation to connect various high-voltage elements at plants and substations allows providing a decrease in the electric energy losses, increase in reliability and safety of operation, as well as improving the ecological situation at the plants.

TL;DR: It is shown that the pertinence of signal vectors to a specific region makes it possible to unambiguously identify the absence or supply of voltage for each separate conductor bus.

TL;DR: In this paper , the results of the physical modeling of the formation processes of upward discharges from grounded objects in the artificial thunderstorm cell's electric field are presented, and the diapason of the optimal tip radii for a lightning rod or lightning conductor, which allows for the most probable formation of the first impulse streamer corona, with the parameters providing the best conditions for the upward leader's start.
