Publication number: 20170316875Abstract: An integrated fluxgate device, which includes a magnetic core, an excitation coil, and a sense coil. The magnetic core has a longitudinal edge and a terminal edge. The excitation coil coils around the longitudinal edge of the magnetic core, and the excitation coil has a first number of excitation coil members within a proximity of the terminal edge. The sense coil coils around the longitudinal edge of the magnetic core, and the sense coil has a second number of sense coil members within the proximity of the terminal edge. For reducing fluxgate noise, the second number of sense coil members may be less than the first number of excitation coil members within the proximity of the terminal edge.Type: ApplicationFiled: January 6, 2017Publication date: November 2, 2017Inventors: Dok Won Lee, Sudtida Lavangkul, Erika Lynn Mazotti, William David French

Publication number: 20170316877Abstract: The present invention provides an expandable and flexible apparatus that can be installed on a device including but not limited to a bushing current transformer (BCT), a control power transformer or a toroidal power transformer. Such an apparatus provides at least one connection point on the device that it is installed on. The apparatus comprises a terminal, a terminal plate, a terminal plate expansion strip or a combination thereof. The apparatus is novel because it has an expandable connection that allows for many terminals to link and be positioned in desired configurations and distances, a linking system that makes the apparatus flexible and allows it to follow the contours of the device, and an anti-rotational provision that holds the terminal in position while the user is connecting wires to the apparatus.Type: ApplicationFiled: April 29, 2016Publication date: November 2, 2017Inventor: Scott McCloskey
