The temperatures of transmission lines have traditionally been estimated by means of ampacity tables that are calculated from expected average weather conditions and values that have been considered valid for a whole season. But in reality, a conductor's position and temperature vary greatly with weather conditions over much shorter time intervals. One solution is to base real-time estimates on instrument readings, but an even better method uses software to calculate the mechanical and thermal status of the conductor.
