초록
In this paper, time variation properties of acoustic emission pulse were studied from low density polyethylene by using the self developed measuring system of aucoustic emission. When AC 15[kVrms] were applied to specimen of needle shape voids(0.5, 1.0, 1.5, 2.0[mm]), the breakdown time of void specimen was quite shorter than that of non-void specimen, thus the quick accurance of inception discharge were confirmed. It is observed that the skewness of the phase angle for applied voltage distribution phase, the average pulse of amplitude and the number of pulse are characteristic quantity of discharge.
