A conductive bus member operable over a selected operating frequency range includes a cylindrical main body and first and second legs secured to the main body at first and second points whereby first and second current paths having first and second impedances are defined between the first and second points. A predetermined relationship between the first and second impedances is maintained over the selected operating frequency range.

Conductive bus member and method of fabricating same

An electrical device is capable of sensing both AC and DC current which is flowing through an electrical circuit. The electrical device bifurcates the current into separate paths, wherein impedance of each path has a constant relationship to each other. In a further embodiment, the electrical device includes a current sensor for measuring current flowing through the circuit. The sensor is of a type which does not introduce insertion loss.

Frequency-insensitive current sensor

A current sensor operable over a selected operating frequency range includes a flux concentrating core. The core is fabricated by forming a series of tape-wound laminations into a desired closed shape, securing the laminations together at a point and removing material at the point to create a gap.

Method of fabricating a magnetic flux concentrating core

This invention relates to an electric power generation and distribution system, and more particularly to an electric power distribution module for use in such systems, having an insulative support structure which includes integral therewith electrically conductive means which define a circuit for distributing electric power received from one or more power sources to one or more electrical loads, the insulative support structure also including integral therewith current sensing means for sensing a flow of electrical current in the electrically conductive means.

Electric power distribution module for an electric power generation and

A cooling apparatus for windings provides the ability to cool transformer windings having many turns during high frequency use with most any coolant. The cooling apparatus comprises a thermally conductive, coolant-isolating conduit having a channel therethrough for the passage of coolant disposed between the turns of the winding in heat transfer relationship therewith.
