Patent ID: 8912920

Claim:
A device connectable to an electric power line conductor comprising: an electrically conductive insulated first winding of wire wound into at least two turns having a first end and a second end, wherein the first end is configured to be attached to a first power line conductor; an electrically conductive insulated second winding of wire wound into at least one turn having a first end connected to the second end of the first winding of wire and a second end configured to be attached to a second power line conductor; and a switchable connecting device configured to maintain constant polarity and move between a first position connecting the first power line conductor in series with the second power line conductor, a second position with the first winding of wire in series with the first power line conductor and the second power line conductor, and a third position with the first power line conductor, the first winding of wire, and the second winding of wire connected in series with the second power line conductor.
