EPR lifetime under impulsive voltage stress

Accelerated lifetime tests on EPR specimens were performed with the aim to investigate the endurance under impulsive electric stress at room and 90 /spl deg/C temperature. The results outline that relationship of the electric field on the number of applied pulses, at 63% of probability of breakdown, can be described by the well-known inverse power model.
