A Prediction Method of Emission from Distribution Power Lines in HF Band

Abstract

The elements of distribution lines were individually modeled for moment methods simulation. To confirm propriety of modeling, simulation results of magnetic field emission were compared with measured one from the distribution lines under test. Both cumulative values in emission spectrum are good agreed within 5 dB differences and the propriety of modeling was confirmed. We have investigated dominant parts of emission by simulation using above modeling. And it was clarified that the emission from LV lines is dominant except for near the pole and the drop cable.
