The article is entitled "Excitation type and results of simulated electric field distribution in MV cable termination".
The article discusses the differences in the results of the electric field simulation in a medium voltage heat-shrinkable cable termination with the most probable assembly faults. Two types of voltage excitation were set as the boundary condition for a model of a real object. The first was a typical electrostatic excitation, and the second was the AC voltage with mains frequency. Both were used for cable accessories with selected assembly omissions. Consideration of the effect of the excitation type suggests that for cable accessories, field simulation using only electrostatics leads to unreal results and incorrect inference about the location of zones with the highest electrical stresses.
