DC breakdown voltages of 8-20 p thickpoly(ethy1ene terephthalate) (PET) films were measuredas a function of electrode area. The areas of the measurement electrodes were between 0.045-9.3 cm2.Also 13-15 m2 capacitor elements were tested. Weibull distribution parameters, scale parameter a and shapeparameter p, were fitted to the obtained breakdownstrength data. Based on the small area results, short termbreakdown strength of large area capacitor elementswas predicted. Area extrapolation based on the scaleparameter a was compared with Weibull extrapolation,in which also the shape of the distribution is taken into account. It was concluded that the Weibull extrapolation better represented the large area breakdown strength than the area extrapolation.
