Kurzbeschreibung (Abstract)
High voltage (HV) and extra high voltage (EHV) cables are usually laid in duct banks to ensure a better heat dissipation. One way of modelling the thermal behaviour of duct banks is to consider the construction dimensions based on geometric factors. In this work a methodology is presented for determining geometric factors of EHV duct banks using a best-fit approach. For this purpose, the results of a finite element method (FEM) model and an analytical model based on IEC 60287 are compared and the geometric factor that provides the best approximation is selected. While using the FEM-Model as a reference, it is shown that the presented approach provides a better solution in the steady-state calculation as well as in the transient temperature calculation for analytical modelling than previous literature models.
