Theoretical and Experimental Study on Partial Discharge Test of 10 kV Cable with Oscillating Voltage
Several methods for testing 10 kV cable are compared. The principle of the partial discharge(PD)test with oscillating voltage is analyzed. A large number of onsite tests verify that the PD test with oscillating voltage can really reveal some defects in medium-connection of a cable and its insulation degradation. In addition
the PD mapping characteristics of these defect types are determined. It is suggested that the PD test with oscillating voltage be applied to the acceptance tests of new cables and the cable after repair of defect in medium-connection.
