    摘要： An apparatus for hot spot sensing where the apparatus includes an input unit, a processing unit, and an output unit. The input unit is configured to provide the processing unit with an image of an object that includes a hot spot. The image data of the image includes image data of the hot spot where the image was acquired by a camera. The processing unit is configured to determine a number of pixels in the image corresponding to a size of the hot spot, an average temperature for the hot spot, the determination comprising utilization of pixel values of the pixels in the image corresponding to the size of the hot spot and the number of pixels in the image corresponding to the size of the hot spot, a surrounding temperature in the image, and a corrected temperature for the hot spot.

    摘要： A sensing arrangement for detection of electrical discharges in an electrical apparatus is described. The sensing arrangement includes an acoustic sensor and a signal enhancing structure with a funnel region. The acoustic sensor is positioned outside the funnel region on an apex side of the funnel region. An electrical switchgear is described. The electrical switchgear includes a sensing arrangement for detection of electrical discharges in an electrical apparatus. The sensing arrangement includes an acoustic sensor and a signal enhancing structure with a funnel region.

    摘要： The present disclosure provides a method for detecting an electrical discharge in an electrical apparatus. The method includes sensing an electromagnetic wave using an electrical sensor and generating an electric signal for a predetermined time period, sensing an acoustic wave using an acoustic sensor and generating an acoustic signal for the predetermined time period. The acoustic sensor is associated with at least one compartment of the electrical apparatus. Electrical data is generated based on a quasi-periodic characteristic of electric peak sequences of the electrical signal. Acoustic data is generated based on a quasi-periodic characteristic of acoustic peak sequences of the acoustic signal, wherein the electrical data is combined with the acoustic data to provide an operation status of the at least one compartment.
