1. A method for determining an overload capacity of a high-voltage device, which comprises the steps of:
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;
deriving a lifetime consumption of the high-voltage device, before the request time, from measured values by obtaining an actually consumed lifetime of the high-voltage device and by feeding the actually consumed lifetime to the load-forecasting model as a state parameter, wherein the load-forecasting model determines a maximum overload capacity depending on the actually consumed lifetime; and
determining, via the load-forecasting model, a maximum utilization in the predefined time period.
