Standard for Calculating the Current-Temperature Relationship of Bare Overhead Conductors
The standard describes a numerical method by which the core and surface temperatures of a bare overhead conductor are related to the steady or time-varying electrical current and weather conditions. The method may also be used to determine the conductor current which corresponds to conductor temperature limits. The standard does not recommend suitable weather conditions or conductor parameters for use in line rating calculations.
738-2012
IEEE Standard for Calculating the Current-Temperature Relationship of Bare Overhead Conductors
A 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-ampacity relationships for a large number of conductors nor does it recommend appropriately conservative weather conditions for the rating of overhead power lines. It does, however, provide a standard method for doing such calculations for both constant and variable conductor current and weather conditions.

IEEE Standard for Calculation of Bare Overhead Conductor Temperature and Ampacity Under Steady-State Conditions
The purpose of this standard is to present a simplified method of calculating the current-temperature relationship of bare over-head lines when given the weather conditions.
