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 analyses 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. The remote electrical safety diagnosis system of the present invention comprises: a digital switchboard including the functions of checking electrical equipment in a switchboard room using a contactless arc sensor and a partial discharge sensor on a power line, to diagnose the safety of the electrical equipment, diagnosing an arc or partial discharge in a detected waveform and storing the diagnosed data, and transmitting the diagnosed data to a higher level server; and a digital distribution board including a main circuit breaker and a partial circuit breaker, for checking an AC voltage or current input through the power line, storing the checked data, and transmitting the diagnosed data to the higher level server.
