Abstract :
A method is described for optimizing the field stress on HV bushings-penetrating through a flat grounded casing-by modifying their profile, seeking a uniform distribution of the tangential field along the bushing surface. This results in an increase of the inception voltage for surface flashover on the bushing surface. The dominant effect in the optimization process is ascribed to the inclination angle and the height of the bushing outside the casing
