루프센서의 성능 평가를 위한 교정실험계의 설계 및 제작

초록

In order to evaluate the performance of lightening observation loop sensor, it is required to generate a uniform magnetic flux density in the range from a few kHz to several hundred kHz. In this paper, the calibration experiment and coil-probe were designed and fabricated according to ieee std. 644-1994. Performance evaluation of the calibration experiment was carried out through the comparison between the theoretical and measured values of induced magnetic flux intensity and frequency components for applied currents. As the result, it is confirmed that the magnetic flux density in the calibration experiment has 5.1[%] of error in the range of 1[kHz] ~ 300[kHz].
