Abstract
A current transformer assembly for harvesting power from a primary conductor, such as a power line, for operating electronics, where the assembly is secured to the conductor while the conductor is connected. The assembly includes a current transformer having a transformer structure with a central opening that accepts the primary conductor and a spindle member for accepting a current transformer magnetic tape operating as the core of the current transformer. The assembly also includes a tape carrier secured to the structure on which the transformer tape is wound, and a winding device operable to unwind the transformer tape from the tape carrier and wind the tape onto the spindle member.
