Alim 8200558Studies conducted via the measurement of the breakdown strength to monitor improvement of the properties of the power system cables used in the transmission lines which is usually made of Polyethylene (PE). The PE sample is fabricated in the form of a disc shape containing a variety of semiconducting materials to obtain a layer forming an interface having a semiconducting ground electrode. Each semiconductor material is perturbed with the additive content to observe the improved behavior of the PE specimens. The average breakdown strength of these specimens is determined and analyzed using Weibull statistical methods.]]>Okamoto, T., M. Ishida and N.
