  • Publication number: 20240003959
    Abstract: In an insulation inspection method for detecting creeping discharge that occurs in a coil in an armature, a predetermined impulse voltage is applied to the coil, and an electrical current value of a current that flows to a current detector that is connected to the coil is detected. The detected electrical current value is analyzed to acquire a relationship between a frequency and an electrical current value spectrum in the detected electrical current value. Based on the acquired relationship, a total sum of electrical current value spectrum areas in a high-frequency band is calculated as a high-frequency spectrum area. The high-frequency band differs from a predetermined low-frequency band in which partial discharge that occurs in a portion of a thin coating of the wire configuring the coil can be detected. Based on a magnitude of the calculated high-frequency spectrum area, creeping discharge that occurs in the coil is detected.
