Abstract
In this paper the finite element analysis method and the experiment when mitigating the magnetic field generated by underground power cables are analyzed. We installed a mock test line and measurement system to obtain the magnetic field data. Based on simulations made with the finite elements method software Maxwell 2D this paper presents mitigation offered by Aluminium plates.
A 154 kV Power cable is installed on mock test line in a phase loop shape. And the current source is connected to control the conductor current. In addition, we measured the phase difference between the conductor current and the sheath circulating current using Ni-DAQ. The magnetic field around the power cable measured by the EFA-300 device. Finally, a measurement system was installed to enable synchronized data acquisition in real time using NI-lab view program. In the mock line, the measured results obtained at a distance of 1M above the ground. The measured EMF data were compared with the simulation data. As a result, the difference between the magnetic value and the simulation value was about 3%.
