He characteristic of partial discharge in the electric power cable for PVC 400 volt was investigated in this research. The volt where the discharge starts was higher as the length of cable was longer. When the voltage was increased from 4kV to 7kV, the frequency of discharge was reduced. It was also ensured that the discharge starting point was higher in the calibration by the negative polarity than that of positive polarity.
