Outline of Final Research Achievements

The influence to the transmission signal and the suppression effect of the leaking signal component is studied in this project relating to the 3-wires power line with three conductors.
Electrical apparatuses and power line were modeled by LCR circuits, and a simple power distribution system was constructed. The transmission characteristic was evaluated. The results showed that the influence when using the center conductor as the ground line, is smaller than the influence when using the side conductor as the ground line. The magnetic field strength at 10m distance was calculated by using the circuit model of the power line. A straight line was used for the investigation. As the results, in major cases, the magnetic field strength leaking from the three conductor power line was smaller than the field strength leaking from the two conductor power line.
