Abstract
A method for monitoring a high-voltage electric-current transmission line includes: determining (100) the ampacity (A) of the high-voltage line from a distribution temperature, conduction parameters and meteorological parameters; measuring (202) the current strength effectively transmitted by the high-voltage line using at least one sensor; and monitoring (204), by a monitoring device connected to the sensor, an excess of ampacity (A) by the current strength measured. The determining (100) of the ampacity (A) includes: selecting (108, 110, 112, 114, 116) a value of this ampacity (A) by optimizing a probability of exceeding the distribution temperature, with this probability defined based on a joint probability model (P) of operating current strength and temperature that depends on meteorological parameters; and recording (118) the selected ampacity value in a storage unit of the monitoring device.
