Abstract :
The general approach to transmission line ratings has been deterministic. The proposed combination of a probabilistic planning approach and a deterministic operations view can pragmatically increase transmission capabilities by 20-30% with a 99% availability and a 100% safety. It is proposed that transmission lines should be rated in the same way they are designed, i.e., based on the ruling span. The operating safety requirements that are based on clearances can be maintained by monitoring the tension of the conductor within the ruling span sections.<>
