  • Patent number: 11544554
    Abstract: A determiner which learns acceleration measurement data which has been obtained by an accelerated aging test and indicates that a facility changes from a normal state to an aged state, and advance label data which is obtained by giving a label to data indicating characteristics of aging in the acceleration measurement data. Measurement data of aging diagnosis is obtained from the facility which is operating, teacher aging degree label data is found from a record of maintenance of the facility, and additional data is obtained from the measurement data and the teacher aging degree label data. When a difference between predicted aging degree label data and teacher aging degree label data is greater than a predetermined value, learning data is selected as additional learning data. The additional learning data is learned to update the determiner.

  • Publication number: 20220308093
    Abstract: A current measurement system is configured to measure an alternating-current (AC) current flowing through a conductor. The AC current has a frequency within a measurement range. The system includes a current sensor and a shunt resistor. The current sensor includes a measurement coil configured to be magnetically coupled to the conductor. The shunt resistor has both ends electrically connected to both ends of the measurement coil, respectively. An output voltage across the both ends of the shunt resistor is saturated at a saturation point in a saturation frequency of the frequency of the AC current. An upper limit value of the measurement range including the frequency is higher than a fundamental frequency of the AC current. The saturation frequency is higher than or equal to the upper limit value. The current measurement system improves sensitivity to frequency components higher than the fundamental frequency of the AC current.
