Abstract: A low or medium voltage switchgear monitoring system includes: at least one sensor; a processing unit; and an output unit. The at least one sensor acquires sensor data within a compartment of a switchgear. The sensor data includes first sensor data. The sensor data includes second sensor data. The second sensor data is acquired a set time after the first sensor data. The at least one sensor provides the first sensor data and the second sensor data to the processing unit. The processing unit determines status information for a compartment of the switchgear based on a comparison of the second sensor data to the first sensor data. The output unit outputs the status information.

Abstract: A method for testing a temperature measuring instrument is presented, where the instrument includes at least one sensor that changes its electrical resistance, and/or an electrical voltage that it produces, in response to being exposed to a change in temperature, and where the instrument is configured to be coupled to an object of interest. The method includes changing the temperature of at least one sensor by an amount that is detectable given the measurement resolution of the at least one sensor, by driving an electrical manipulation current through this sensor; obtaining one or measurement values from at least one sensor; and evaluating a state of the measuring instrument, a state of one or more of its sensors, and/or a state of a coupling to an object of interest, from the one or more measurement values.

Abstract: A fault state detection apparatus includes an input unit and a processing unit. The input unit receives condition monitoring data. The processing unit implements a trained machine learning algorithm to analyze the received condition monitoring data to determine if the received condition monitoring data is associated with a fault state. The trained machine learning algorithm was trained on the basis of a plurality of non-fault state condition monitoring data and associated ground truth information and on the basis of a plurality of fault state condition monitoring data and associated ground truth information. A subset of the plurality of fault state condition monitoring data was generated from one or more non-fault state condition monitoring data. Generation of fault state conditioning monitoring data in the subset of the plurality of fault state condition monitoring data comprises a transformation of non-fault state condition monitoring data to fault state condition monitoring data.

Abstract: A system and method for monitoring a device includes a temperature sensor, a processing unit, and an output unit. The temperature sensor acquires a temperature measurement during a heat-up phase of a component and provides a temperature measurement to the processing unit, which selects a simulated transient temperature distribution of the simulated component of the simulated device from a plurality of simulated transient temperature distributions of the simulated component of the simulated device. The selection comprises a comparison of the at least one temperature measurement with the plurality of simulated transient temperature distributions at an equivalent time point in the simulated heat-up to a time point at which the temperature measurement was acquired. When a hot spot is developing an output unit outputs an indication of a fault associated with the component.

Abstract: A system for monitoring a switchgear includes multiple infrared cameras with fields of view; a processing unit; and an output unit. The cameras acquire multiple image data of a plurality of phases of the switchgear, and the processing unit determines whether there is a phase imbalance in a specific phase comprising a determination from a plurality of image data that temperature information for a plurality of component parts and/or a plurality of connections for that specific phase has an overall enhanced temperature compared to the temperature information for the same plurality of component parts and/or the same plurality of connections for one or more other phases of the plurality of phases. The output unit is configured to output information that a fault or load imbalance has occurred in a phase.

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.
