Abstract: | Fourteen possible types of magnetic flux density meters based on the Faraday induction principle have been mathematically simulated. The different readings obtained from each type when the magnetic flux density is more complex than the ideal case of a single frequency (60 Hz) with linear polarization are shown. Using a real database of residential flux densities from 17 homes, it is shown that the presence of harmonics and elliptical polarization can result in significant deviations in readings between meter types. The highest variations from the total RMS (root mean square) flux density are found with broadband meters that have derivative responses or corrected peak detectors |
