Abstract: A method determines an overload capacity of at least one high-voltage device. In which method, measurement values are continuously recorded by sensors located in or on the high-voltage device. The measurement values and/or values derived therefrom are transmitted via a near field communication connection from the sensors to a communication unit of the high-voltage device. The communication unit is connected to a data processing cloud. For high-voltage devices, a load forecast request is created for a predetermined time-period and is transmitted to a data processing cloud. For each high-voltage device, a state parameter is determined in part based on the measurement values. The load forecast request and each state parameter are transmitted at a request time to a load forecasting model; and the load forecasting model determines the maximum load in the predetermined time period.

Abstract: For diagnosing a railroad switch with a point machine, a first and a second time series of a sensor signal of the point machine are received. Moreover, changes in the first and the second time series are detected indicating changes of operational conditions of the point machine. Furthermore, an event point of a respective change in the first and in the second time series is allocated to a respective component of the railroad switch or of the point machine based on a simulation modelling the respective component. Then for a respective component: event points allocated to that respective component are identified, the sensor signal at a first identified event point in the first time series is compared with the sensor signal at a second identified event point in the second time series, and depending on the comparison a component-specific fault information and an identification of the respective component are output.

Abstract: For fault detection in a switch system including multiple switches, for a respective switch its operating data are acquired and transmitted to a central control. For a respective first switch of the switch system, a deviation of an operating behavior of the first switch from a set behavior is determined by the central control on the basis of its operating data. If there is a deviation, operating data of the first switch are compared with operating data of other, second switches of the switch system and, depending on that, a second switch with similar operating data is selected.
