PROBLEM TO BE SOLVED: To provide a rating system for a partial discharge generation position, capable of rapidly performing the rating of the partial discharge generation position.SOLUTION: A rating system for a partial discharge generation position comprises: electrodes 10, 11 consisting of one set of two electrode plates 10A, 10B, 11A, 11B disposed on an outer peripheral side of an insulator 3 for insulating a conductor 1 and wound so as to surround whole circumference of the conductor 1 at a plurality of measurement points in relation to the axial direction of the conductor 1 of a CV cable I which is a transmission channel through which a partial discharge signal generated by a partial discharge is propagated; and a measurement part 14 for generating detection impedance signals S1, S2 expressing detection impedances by detecting the detection impedances based on the partial discharge signal up to a UHF band via the electrodes 10, 11 at the measurement points. |
