The dielectric strength of capacitor paper impregnated with askerels

The effect of switching surges on the dielectric strength of Askarel impregnated capacitor paper is less than for standard impulses and approximately the same for A.C. From the practical point of view the small variation in breakdown strength resulting from a change in the wave front duration from 35/110 μ sec to 600/2000 μ sec can be neglected in the design of capacitors.
