  • Abstract
    The experimental results of study of the tree-inception time (τi) in the divergent field for the three-layer dielectrics are presented in this paper. It is shown that the tree-inception time may be essential increased due to the application of dielectric barriers with high permittivity. It is determined that the tree-inception time depends on the barrier position in the insulating gap and it has a maximum at the optimal barrier position. In doing so, the tree-inception length (li) has a minimum value at this barrier position. Good agreement between the coefficient of the local field nonuniformity and the tree-inception time or the tree-inception length was found.
