TEMPERATURE RISE ESTIMATION OF AN OVERHEAD POWER CONDUCTOR DUE TO A WILDFIRE

摘要

Fires in open land covered with grass, brush, or timber are often termed wildfires. During a wildfire the overhead conductors of a passing through distribution line suffer a thermal stress that deteriorates their mechanical properties.This paper presents a fire model that allows for the estimation of the temperature rise of the conductors, if we know some characteristics of the fire. The knowledge of the temperature rise is necessary for the study of the effects on the overhead conductors.
