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.

Abstract: The present disclosure discloses a coil structure for a dry-type transformer and a winding method therefor. The coil structure for a dry-type transformer comprises multiple coil layers and a supporting framework, which is provided with multiple supporting layers. The spacer blocks of each intermediate supporting layer comprise a rising spacer block for rising and supporting spacer blocks in addition to the rising spacer block, a thickness of the rising spacer block being greater than a thickness of the supporting spacer block, and the rising spacer blocks of several intermediate supporting layers being staggered along the circumferential direction. The present disclosure decreases the height of the entire coil efficiently, meanwhile abates the problem that the wire is centralized in a single area, inhibits the temperature rise phenomenon of transformers efficiently, and prolongs the lifetime of transformers.

Abstract: Systems and methods include using a magnetic core winder to install a powerline-mounted device with a non-gapped magnetic core, therefore reducing the weight of the powerline-mounted device while still harvesting equal or more power than a large cross-sectional and gapped magnetic cores. In particular, the methods include installing bobbin(s) and a core housing on a powerline and winding strip/ribbon core material onto the core housing. The bobbins may be wound axially opposed to on a toroid winder, which improves the accuracy of turns count of the magnetic core. The improved accuracy of turns count may increase the accuracy and/or tolerance of magnetic component(s) of the powerline-mounted device.
