  • Patent number: 9915685
    Abstract: A current detection system includes: first and second magnetic plates arranged in parallel with a predetermined distance; a bus bar for flowing current; and a magneto-electric conversion element converting a lateral direction component of a measurement object magnetic flux, generated by current flowing through the bus bar, to an electric signal. When an external magnetic flux in a lateral direction passes through an accommodation space between the first and second magnetic plates, a trajectory of the external magnetic flux is bent by the first and second magnetic plates, and the accommodation space is divided into a permeable space, through which the external magnetic flux passes, and a non-permeable space, through which the external magnetic flux does not pass. The bus bar is arranged in the accommodation space. The magneto-electric conversion element is arranged in the non-permeable space. The bus bar and the magneto-electric conversion element are lined in the height direction.

  • Patent number: 9857406
    Abstract: Disclosed are a three-phase wiring detection device and a coincidence phase detection method. The three-phase wiring detection device and the coincidence phase detection method compare a power factor relationship between a three-phase voltage and a three-phase current, and determines whether a coincidence phase is coincident between the three-phase voltage and the three-phase current, thereby checking whether the coincidence phase is accurately coincident. Therefore, whether the coincidence phase is coincident between the three-phase voltage and the three-phase current can be checked, and a function of a reverse phase detector and a function of a coincidence phase checker can be implemented. Also, the three-phase voltage and the three-phase current can be accurately detected.
