ABSTRACT
The objective of this work is to determine if a relationship could be found between dielectric strength and other basic properties of electrical insulating materials such as volume resistivity, dielectric constant or relative permittivity and dissipation factor or loss tangent, on empirical basis, by using variables predicted by basic theory. A simple equation to predict the dielectric strength of a solid insulating material in the ambient medium has been proposed using ASTM electrode system. Also, Artificial neural network theory is used to predict the value of dielectric strength of solid insulating materials provided thickness of insulation, volume resistivity, dissipation factor and dielectric constant are known and the results thus obtained have been compared with those obtained by the proposed equation.
