摘要： PROBLEM TO BE SOLVED: To provide a direct current power cable abnormality detection device which can continuously monitor insulating coating of the direct current power cable, easily and surely detect the deterioration, inform a manager of the abnormality of the direct current power cable, and allows the manger to take a ground fault prevention measure for the direct current power cable.
SOLUTION: The direct current power cable abnormality detection device detects the abnormality of the direct current power cable 1 which is equipped with an electric wire 2, the insulating coating 3 coating the electric wire 2, a conductive part 4 disposed at the periphery of the insulating coating 3. The direct current power cable abnormality detection device is equipped with a resistance part 12 connected between the conductive part 4 and the ground, a voltage detector 13 detecting the voltage generated in the resistance part 12, and a signal output part 16 outputting the abnormal signal when the output voltage of the voltage detector 13 is not less than the set level previously set.
