PURPOSE: A current measuring system and a method for assembling thereof are provided to easily form a miniature circuit breaker box by permitting proximity interval between circuit protection devices. CONSTITUTION: A current measuring system(10) measures a current passing through a conductor. A first sensor(16) measures first magnetic flux. The first sensor generates a first signal(20). The first signal is proportional to the first magnetic flux. A second sensor(18) measures second magnetic flux. The second sensor provides a second signal(22). The second signal is proportional to the second magnetic flux. The second sensor has sensitivity in regard to a stray magnetic field higher than the first sensor. A processor(14) is connected with the first sensor and the second sensor. The processor receives the first signal and the second signal. |
