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.

Abstract: A current transformer includes a pre-formed core forming a closed loop with a flexible axially wound secondary winding. A continuous length of wire is axially coiled around a flexible bobbin to form a secondary winding. The resulting secondary winding may be slid onto the closed loop of the pre-formed core. The flexibility of the axially wound secondary winding facilitates conformity to a non-linear shape of the pre-formed core.

Abstract: The present disclosure relates to powering distributed sensors used to monitor electrical and/or environmental conditions and to powering other equipment associated with electric power systems. In one embodiment, a system may be used to mount a sensor in proximity to a reference conductor. An electric field power conversion subsystem may generate a usable electric potential from an electric field created by the electric power system and existing between the reference conductor and another conductor (e.g., another phase conductor, a ground conductor). The sensor powered by the usable electric potential may provide a measurement of a condition associated with the electric power system. A communication subsystem powered by the usable electric potential may communicate the measurement of the condition to a monitoring system.

Abstract: A current transformer (CT) isolation clamp is mounted to a phase conductor and includes a step-down CT transformer and a passive isolation transformer. A three-phase power-harvesting sensor system includes a plurality of CT isolation clamps mounted to phase conductors in a three-phase power system. An electronics module is connected to the CT isolation clamps. The electronics module may include a sensing circuit to determine power characteristics of the three-phase power system based on the outputs of the CT isolation clamps. The electronics module may include a communication subsystem to transmit the determined power characteristics to local or remote devices. Additionally, the electronics module may include a power harvesting circuit to harvest power to operate the sensing circuit and the communication subsystem.
