A Modelica model of the thermal and mechanical phenomena of bare overhead conductors is presented. The geometry of the catenary is also modeled as an important part of the mechanical phenomena.The model has been compiled and tested using OpenModelica. Some application examples are also presented to illustrate some analysis that can be done with the model.
