Implementation of finite element analysis and hybrid IEC-models in online ampacity tool

Abstract

Current tools for ampacity calculations are based on
analytical expressions, and empirical expressions for
complex laying geometries that in practice cannot be
solved analytically, formulated in the IEC standards. Non-standard or highly complex laying geometries must be
simplified and approximated, which often result in less
accurate calculated ampacities. Norwegian utilities and
industry have supported R&D to develop an online
ampacity tool based on finite-element analysis (FEA).
Some parts of IEC 60287 formulae have been included to
reduce computation time. The result is an easy-to-use and
accurate online tool for ampacity calculations.
