Abstract

Analysis was conducted on the nature and characteristics of an H-field sensor for power system electromagnetic compatibility (EMC) measurements. Based on the original calibrated response curve of the magnetic-field (H) sensor and steepest descent theory, an analog model has been created to represent the sensor's transfer function. This function was converted into a set of digital algorithms by the bilinear transformation method, thus allowing subsequent signal processing on available software. The digital correction model for the sensor gives an estimated error of within 8% for all the relevant frequency components. The results present some general analysis methods for power system EMC measurements.
