Abstract :
A dependence of the electric strength on thickness, area and volume of dielectric is demonstrated for polypropylene film. It is found that the electric strength of theoly polymer film decreases with volume. It is shown that theunc function of electric strength is not simply dependent on the volume as obtained from theory of extreme values, but that an increase of the volume by increasing the thickness of the dielectric is much more significant than the same increase of the dielectric volume caused by an increase in area.
