Numerical Computation of Electric Field

ABSTRACT In a high-voltage equipment, as a thumb rule, the cost of insulation increases with the cube of voltage rating. However, practical experience shows that insulation failure is the most frequent cause of major breakdown of electrical equipment. Hence, it is of paramount importance that the insulation in electrical equipment withstands the electric field stresses with adequate safety margin. For this purpose, it is necessary to determine the electric field distribution precisely. An inherent advantage of analytic solutions is the exactness. However, analytic solutions for the electric field are available only for problems having simple configurations. When the complexities of theoretical formulae ...
