Multi-branch current/voltage sensor array

A current-sensing device for measuring individual currents passing through multiple wires corresponding to multiple branch circuits, the current-sensing device comprising:

• a first frame member having a first set of multiple ferrite cylinder portions corresponding to the multiple branch circuit wires integrated within the first frame member;
• a second frame member having a second set of multiple ferrite cylinder portions corresponding to the first set of ferrite cylinder portions, such that when the first frame member is fastened to the second frame member in a closed position, the first set of multiple ferrite cylinder portions are located proximate to or contacting corresponding ones of the second set of multiple ferrite cylinder portions to form substantially closed magnetic flux loops surrounding the corresponding wires of the multiple branch circuits, wherein the first and second sets of ferrite cylinder portions are positioned by the first frame member and the second frame member, respectively, such that cylindrical voids defined between each of the first set of ferrite cylinder portions and corresponding ones of the second ferrite cylinder portions are parallel and spaced appropriately for receiving multiple branch circuits emanating from standard circuit breakers spaced at intervals of one-half inch, one inch or two inches;
• multiple semiconductor current sensors coupled to the corresponding magnetic flux loops formed by the first and second sets of multiple ferrite cylinder portions;
• multiple voltage-sensing elements comprising a film affixed to or deposited within corresponding ones of at least one of the first set of ferrite cylinder portions or the second ferrite cylinder portions for sensing electrical potentials at corresponding ones of the multiple wires;
• and
• a processing circuit integrated within the first frame member for measuring outputs of the multiple current sensors and providing information determined from the multiple current sensors to an external system via an interface.
