About This Item

 

Full Description

Scope

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.

Purpose

The purpose of this document is to provide a standard method for the calculation of the current-temperature relationship of overhead power line conductors for steady-state and transient cases. This method may be used to develop line ratings including dynamic ratings.

Abstract

Revision Standard - Active. 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.
