1. A monitoring method for an electric power transmission device having a first phase conductor and a second phase conductor, the monitoring method comprising:
acquiring a temperature of the first phase conductor and a temperature of the second phase conductor;
comparing the temperature of the first phase conductor with the temperature of the second phase conductor;
if there is a difference between the temperatures of the first and second phase conductors, performing a signaling; and
producing a forecast for a characteristic of a temperature load on at least one of the phase conductors from ascertained measured values.
