Abstract:
1. A method for determining the electrical loadability of power lines by temperature measurement, comprising the steps of: determining estimated values for weighted load parameters in a data processing system based on existing monitoring values, values of individual measurements, and weighting values assigned to individual measurements, wherein the weighting values of ambient temperatures, wind velocities, wind directions, solar radiation, each individually or in at least one combination, are saved in the data processing system; arranging at least one sensor on a clamp, a support, a connector, or a fixture for the power line or providing the at least one sensor as a component of a clamp, a support, a connector or a fixture of the power line and connecting the at least one sensor to the data processing system; measuring a temperature with the at least one sensor; determining, based on the electrical current of the power line and the temperature measured by the at least one sensor, taking into account the weighted load parameters, a time-dependent electrical load in the data processing system; calculating, in the data processing system, load currents for the power line as a load prognosis of the power line by using a weighted temperature of the conductor of the power line, based on the weighted load parameters and an ambient temperature with consideration of the limit temperature of the power line.
