Abstract: Disclosed herein is a cable fault diagnosis system and method, wherein when an application signal and a reflected signal overlap each other due to the proximity of a fault location to an application location or when the intensity of the reflected signal is weak and thus falls outside of a prescribed fault diagnosis range due to remoteness of the fault location from the application location, a correction location, at which a correlation function value has a global maximum, is derived on the basis of a prescribed correlation function for an application signal applied to a cable to be inspected and an acquired reflected signal, a correction signal, which is a reflected signal from which the application signal is removed at the derived correction location, is calculated, the distance between the correction location and the acquisition location is derived on the basis of a time delay, which is calculated on the basis of the calculated correction signal and the reflected signal at the acquisition location, and a pr

Abstract: The present invention relates to an electrical safety diagnosis system and apparatus, which are configured to enable sensed data on user surroundings in a U-city environment, such as electrical safety data for switchboards and distribution boards, and water leakages, faulty outlet connections, etc., to be managed remotely by a server at a U-city integrated information center. In particular, the present invention relates to an electrical safety diagnosis system and apparatus which use a U-city integrated information network to preemptively perform checking and analyzes for potential electrically-induced disasters that can occur in public facilities, stores, buildings, and homes within a U-city, by means of a U-city integrated information center, and prevent electrical fires or shocks at the electrical equipment of switchboards or distribution boards, and dangerous conditions (such as water leakages, abnormal temperatures, gas, and faulty outlet connections) in facilities used by users.
