Abstract

Aiming to meet the high current test requirements of a certain type of DC circuit breaker entrance copper

the basic model of RA-HCT was built. Meanwhile

from the perspective of mechanism

the influence of external magnetic field on the measurement accuracy of the sensor was analyzed. Then

the influence model of external parallel wires on the RA-HCT was built

the measurement error calculation method was achieved. In addition

12 dot matrix RA-HCT was designed and implemented. Furthermore

compared to standard experiment

the maximum difference of theoretical error and actual error of x-axis was about 10%

and the maximum difference of y-axis was about 2%

which meet the requirements of equipment

verified the correctness of the algorithm and provided a theoretical basis of improving the measurement accuracy of the sensor.
