How to Model 2D Cables in COMSOL Multiphysics®
Durée: 55:52
Watch this 60-minute presentation on 2D cable modeling to learn how to use the COMSOL Multiphysics® software for modeling cable systems in 2D. Here, we demonstrate the modeling of a submarine cable and discuss topics such as capacitive, inductive, and thermal analyses; armor and phase twist; and various bonding types. Many of the topics covered apply to terrestrial cables as well.
Discussion topics include:
- Capacitive effects in cables: dielectric loss and electromagnetic breakdown
- Capacitance and charging current, and a comparison with analytical models
- Interpreting results in the frequency domain
- Litz wires and Milliken conductors
- Suppressing skin and proximity effects in the phases, screens, and armor
- Inductance, AC resistance, and a comparison with the DC resistance
- Evaluation of the resistive loss and the magnetic hysteresis loss
- Thermal effects in cables: one-way or two-way coupled induction heating
- Temperature dependency: active and passive conductors
