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.

Method for determining the overload capacity of a high-voltage device

A method determines the overload capacity of a high-voltage device. The method includes creating a load forecast request for a predefined time period, determining an operational state of the high-voltage device by obtaining state parameters, transmitting the load forecast request and the state parameters at a request time to a load-forecasting model, and determining the maximum utilization in the predefined time period by the load-forecasting model, with which the overload capacity of a high-voltage device can be fully exploited. A lifetime consumption of the high-voltage device before the request time is derived from measured values by obtaining an actually consumed lifetime and the actually consumed lifetime is fed to the load-forecasting model as a state parameter. The load-forecasting model then determines the maximum overload capacity depending on the actually consumed lifetime.
