| Abstract |
In this paper, the design, manufacture, and characteristic evaluation of the current transformer as a power source were discussed to use unbalanced currents flowing through the overhead ground line due to load imbalance in the three-phase four-wire transmission line. In the theoretical calculations on the output characteristics of a current transformer, approx. 30A of the unbalanced current show to produce enough power about 14.7W. And it is confirmed that the battery can be stably charged at 29.7W for the load operation even if the imbalanced current is about 20A. Therefore, it was shown that the current transformer and power supplies developed in this study can be sufficiently used as operating power sources for various loads installed in the transmission line. |
