MONITORING AN ELECTRICAL ENERGY TRANSMISSION DEVICE

In a method for monitoring an electrical energy transmission device, time-resolved operating state data, environmental state data, and/or sensor sensor data are recorded. The operating state data relate to current, past and/or future operating states of the electrical energy transmission device; the environmental state data relate to current, past, and/or future states in an environment of the electrical energy transmission device; the sensor data are detected by at least one sensor of the electrical energy transmission device. The operating state data, the environmental data, and/or the sensor data are processed with a computational model to calculate a temperature curve of current, past and/or future temperatures of at least one module of the electrical energy transmission device. Based on the calculated temperature curve, a thermal load capacity of the module is determined based on a thermal load threshold for the module.
