Appl. No.:

10/962682

Inventors:

Mark G. Solveson - Oconomowoc WI, US
Charles J. Luebke - Sussex WI, US
Joseph C. Engel - Monroeville PA, US

Assignee:

Eaton Corporation - Cleveland OH

International Classification:

G01R 15/18
G01R 15/20

US Classification:

324127, 324117 H, 324117 R

Abstract:

A sensor apparatus for a power bus including a current and a temperature includes a housing and one or more sensors. Each of the sensors is adapted to sense one of the current or the temperature of the power bus. A radio transceiver circuit is adapted to transmit a first wireless signal and to receive a second wireless signal. A processor is adapted to input the sensed current and the sensed temperature from the sensors and to output corresponding signals to the radio transceiver circuit in order to transmit the first wireless signal. A power supply is adapted to employ voltage produced by magnetically coupling the power bus to one or more coils, in order to power the sensors, the radio transceiver circuit and the processor from flux arising from current flowing in the power bus.

Abstract:

A back-pack power supply module is for a circuit interrupter including an elongated line conductor. The back-pack power supply module includes a housing having an opening therethrough. The opening receives the elongated line conductor, which passes through the opening. A power supply circuit is housed by the housing and is adapted to input a line voltage from the elongated line conductor and output direct current voltages. A capacitive divider circuit includes two capacitors electrically connected in series between a first terminal and an output of the capacitive divider circuit. One of these two capacitors receives the line voltage. The two capacitors are embedded in insulation within one portion of the housing. Another capacitor is electrically connected between a second terminal and the capacitive divider circuit output. The other capacitor is disposed in another portion of the housing opposite the opening.
