Abstract
On-site partial discharge test by use of AC voltage has been considered not to be appropriate for the extruded power cable due to their large capacitance depending on their lengths. Therefore, it is proposed, in this work, to use switching impulse voltage of which the front time is set from 1ms to 10ms. This newly proposed method enables us to simulate the 1/4 period of power frequency at 60 Hz and to obtain similar effect of AC voltage test. Our tentative results show that 51 voltage is proved to be an alternative method, replacing AC voltage, by which partial discharge was well produced from the artificial defects integrated in 22.9kV distribution power cables.
