Abstract
With the three dimensional magnetic field measuring system dealt with in this paper, accurate measurements and analyses of extremely low frequency(ELF) magnetic fields caused by starting and/or operating electric devices and power installations can be conducted. To obtain high performance for lower frequency and spatial components without any distortion, the measuring system is designed as three dimensionally including the multiturn loop-type magnetic field sensors, differential amplifiers and active integrators. As the results of calibration experiments, the frequency response characteristics of the measuring system range from 8[Hz] to about 53[kHz] for each direction of x, y, z axes, and the response sensitivities are 9.54, 9.21,
본 논문에서는 전기기기 및 전력설비의 운전 조작중에 발생하는 극저주파 영역(ELF)의 자장을 측정 및 분석 할 수 있는 장치로써 멀티턴 루우프형 센서를 이용한 3차원 자장측정계에 대해 기술한다. 저주파특성의 개선과 왜곡없는 공간자장성분의 측정 등 우수한 성능을 얻기 위해서, 자장측정계를 멀티턴 루우프형 센서와 증폭기, 능동성 적분기로 구성하여 3차원적으로 설계 제작하였다. 교정실험을 통하여 측정계의 고유응답특성을 산출한 결과, 주파수대역은 x, y, z 축 각각 8[Hz]에서 53[kHz] 정도이고, 응답감도는 9.54, 9.21,
