Definition

A method to determine the real‑time thermal ampacity (current carrying limit) of an overhead transmission or distribution conductor by using current measurements, conductor temperature or sag sensors, and environmental data (ambient temperature, wind, solar radiation) coupled with a thermal model, rather than relying solely on a fixed conservative static rating.
