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: An experimental investigation of impulse transients in the windings of a full-scale mockup model of an active part of a 20-kV A SSVT with a rated voltage of 110 kV shows that, unlike in the case of power transformers with disc windings, more significant effects on the insulation are produced when no load is applied on the low-voltage windings.

TL;DR: A database of the generic solutions for protection from lightning was developed, it being a structured collection of files containing the layout of buildings and equipment at the substation and the arresters’ layout plan with taking into account the electromagnetic compatibility.

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: In this article, a general model that takes into account precipitation of particles, entering the ESP inlet (direct precipitation), as well as precipitation of reentrained particles (secondary precipitation), is presented.
