Abstract
The purposes of this paper ensure for the economical efficiency, accuracy, and good applications in domestic site set up the power installations. For the efficient conduct of these purposes, there are measured the partial discharge(PD) used by current probe and compared with detected signal of UV sensor. As the results, PD generated about 35% of breakdown voltage in polymer insulator. UV signal due to high voltage in polymer insulator is detected from about 1.7mV at 30kV to about 3mV at 70kV. Signal detected by ultra-sonic is increased at about 75% of breakdown voltage abruptly. It appears that error range is increased in boundary. UV sensor is needed must use from the practical and economical points of view.
