A New Industrial Cable System Parameter Calculation Methodology Based on 3-D Finite Element Analysis

High-frequency phenomena require appropriate models to be accurately reproduced and analyzed by means of computational simulations. Within industrial facilities, insulated cables are widespread and their modeling in a broad range of frequencies is complex due to the proximity between these and particular issues concerning the installation methods. In this context, in this article, the authors improve a methodology presented previously to make it suitable for the most used installation methods in industry, namely the perforated and the ladder-type cable trays, not addressed so far. The required modifications regarding the methodology reformulation are explained and the obtained results are presented and compared to those derived from the previously available technique, followed by discussions and physical insights.
