A dielectric breakdown generated spot calculating unit(13) computes the generation spot of a dielectric breakdown by analyzing the partial discharge signal transmitted at a time gap and detected by the first partial discharge signal sensing unit. A second partial discharge signal sensing unit(14) detects a partial discharge signal transmitted from the power cable. A partial discharge judging unit(18) judges whether the signal is generated due to a dielectric breakdown of the power cable or not, by calculating the size of the partial discharge signal output from the second partial discharge signal, receives the generation spot of a dielectric breakdown by controlling the dielectric breakdown generated spot calculating unit, and cuts off over-voltage from being applied to the power cable. An over-voltage cut-off unit(19) cuts off over-voltage applied from a voltage applying unit to the power cable, according to the control of the partial discharge judging unit.
