P738 - Standard for Calculating the Current-Temperature Relationship of Bare Overhead Conductors
Project Details
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.
