An experimental technique is described for measurement of the relative resistance of solid insulating films to breakdown by partial discharge using an IEC(b) electrode geometry together with sinusoidal voltages of frequencies from 1 to 60 kHz and pulse voltages at a repetition rate of 15.625 kHz. The technique is employed for determining the accelerated lifetime of polyimide and PVC films. The temperature rise under discharge condition was also measured. The results show that within the 100… CONTINUE READING
