IEEE Standard for Calculating the Current-Temperature Relationship of Bare Overhead Conductors IEEE Standards Board Approved June 17, 1993 Sponsor Transmission and Distribution Committee of the IEEE Power Engineering Society Abstract: A simplified method of calculating the current-temperature relationship of bare overhead lines, given the weather conditions, is presented. Along with a mathematical method, sources of the values to be used in the calculation are indicated. This standard does not undertake to list actual temperature-capacity relationships for a large number of conductors for a large number of conditions.
