Calculation of Ampacity for Bare Overhead Conductors

Many standards have published for calculating the ampacity of bare overhead conductors. Although these standards use the same basic heat balance concept, they use different approaches to calculate ampacity ratings. This paper looks at the different approaches used to calculate individual heat balance terms, at the overall impact of these terms on the ampacity rating. And this paper is proposed to the selection of proper standard and atmospheric conditions for calculating the ampacity of bare overhead conductors.
