Abstract
To estimate a electrical performance of the extra high voltage XLPE cable the discharge properties due to shift of void position were investigated. The Φ-q-n properties have been measured at room temperature by rising voltage ratio of 0.5[kV]. An obtained data was stored to personal computer through A/D converter. The period of applied wave form and discharge values were divided into 64 parts and discharge values generated during 10 seconds were accumulated by phases. As a result, it was confirmed that the charge, phase angle and counts of discharge changed due to void position.
