<p>The present invention relates to a monitoring device of an optical composite underground power line and, more specifically, to a monitoring device of an optical composite underground power line capable of checking and diagnosing breakdowns of a sensor which monitors the state of an optical composite power line installed underground by a set period. According to the present invention, since a diagnosis failure occurring by a structural defect of the underground power line is minimized, it is possible to improve an effect of preventing an accident caused by malfunction or breakdown.</p> |
