Abstract: A system and method includes at least one temperature sensor, a processing unit, and an output unit. The temperature sensor acquires a temperature measurement at a first location of an operational device, which first location is in thermal contact with a second location of the operational device. The processing unit selects a simulated temperature distribution of the first location of a simulated device from a plurality of simulated temperature distributions of the first location and compares the temperature measurement with simulated temperature distributions of the first location, and determines whether a hot spot exists or is developing at the second location. The determination comprises utilization of a correlation between the simulated temperature distribution of the first location and the second location for the selected simulated temperature distribution of the first location of the simulated device.

Abstract: 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.

Abstract: An apparatus for prediction of the residual lifetime of an electrical system includes: an input unit; a processing unit; and an output unit. The input unit provides at least one sensor data from at least one sensor to the processing unit, the at least one sensor data including a measurement of at least one physical parameter of at least one component of an electrical system. Each sensor data is associated with a corresponding sensor and relates to a measurement of one physical parameter of a corresponding component of the electrical system. Each sensor data extends over a plurality of time windows and is assigned to a certain data class, such that sensor data at a particular time window has a value that falls into one of the data classes. For each sensor data the processing unit assigns the sensor data at each time window into a corresponding measurement window.

Abstract: A surface temperature sensor has a first geometric contact surface for determining the temperature in a vessel and a second geometric contact surface, wherein the first geometric contact surface and the second geometric contact surface are in point and/or linear contact and at least partially spaced variably from this. For improvement of thermal contact an adapter between the first geometric contact surface and the second geometric contact surface may be made of metal, whereby the process vessel facing side has a polygonal surface structure and the temperature sensor facing side of a sack-shaped recess.
