IEEE Standard for Calculating the Current-Temperature Relationship of Bare Overhead Conductors
Abstract: 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 is described in this standard. Contents discussed also include how this method may be used to determine the conductor’s current for a corresponding conductor temperature limit. Please note the content in this standard does not recommend suitable weather conditions or conductor parameters for use in line rating calculations.
Keywords: ampacity, bare overhead lines, current-temperature relationship, IEEE 738™, line ratings
