Abstract: PURPOSE:To detect the defects of a cable by casting laser pulses on the outer surface of the cable, on which DC voltage is applied beforehand, and analyzing the generated induced current. CONSTITUTION:A cable conductor 1 is provided at the central part of a macromolecule insulated power cable A, and an inner semi-conducting layer 2, a cable insulator 3 and in outer semiconducting layer 4 are sequentially provided thereon. A laser pulse generator B emits laser pulses on the outer surface of the cable A. The induced current generated by the emission is detected and amplified with an amplifier C. The waveform is read with an oscilloscope D. For example after the DC of about 60kV is applied on the cable A for about 10 minutes, the conductor 1 and the semiconducting layers 2 and 4 are grounded. The laser pulses are emitted, and the induced current in the conductor 1 is detected. When a charge layer is present in the insulator when the pressure wave caused by the laser pulses is propagated in the cable insulator, an induced current flows through an external circuit. The induced current is proportional to the amount of the charge in the insulator. When projections and voids are present in the insulator 3, the peculiar current waveforms, which are not observed in the normal cable, are observed in the generated induced current. The defect in the insulator is detected ny observing the induced current.
