- Abstract:
- In this study we present a 2D finite element model for computing magnetic fields generated by underground power cables with two-point bonded shields. The model is developed in ANSYS Maxwell 2D low-frequency electromagnetic field simulation software for a typical 12/20 kV three-phase underground power cable system in flat formation, but it can be adapted to any line. The model validation is achieved by analytical computations conducted with a software tool based on the Biot-Savart law and superposition principle. RMS magnetic flux density profiles calculated at various heights above the ground with these two methods correlate very well. This is also true for induced shield currents.
