Patent number: 12104960Abstract: 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.Type: GrantFiled: September 24, 2021Date of Patent: October 1, 2024Assignee: ABB Schweiz AGInventors: Stephan Wildermuth, Holger Kaul, Tomas Kozel, Aydin Boyaci

Publication number: 20230273069Abstract: A system and method for monitoring a switchgear includes an infrared camera, a processing unit, and an output unit. The infrared camera acquires an infrared image of the switchgear, and the processing unit converts it into a binary image. Pixels in the infrared image having a temperature equal to or above a first threshold value are given the same first value. Pixels in the infrared image having a temperature below the first threshold value are given the same second value. The processing unit is configured to implement a Siamese neural network to determine if a hot spot exists in the infrared image.Type: ApplicationFiled: February 28, 2023Publication date: August 31, 2023Applicant: ABB Schweiz AGInventors: Ralf Gitzel, Marcel Dix, Holger Kaul, Tomas Kozel

Patent number: 11609259Abstract: 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.Type: GrantFiled: June 30, 2021Date of Patent: March 21, 2023Assignee: ABB Schweiz AGInventors: Kai Hencken, Yannick Maret, Jörg Gebhardt, Holger Kaul, Jörg Lehmann, Andrej Krivda
