Experiment results of the unwanted influence of a probe fixture in transient electromagnetic field

摘要

Field probes are used extensively in electromagnetic compatibility tests to measure magnitudes of electromagnetic field strength. To achieve accurate measurements in a certain space position, a probe (mounting) fixture or probe stand is always utilized to hold the field probe. The unwanted influence of a probe fixture in transient electromagnetic field is investigated by experiment in this paper. Considering the measurement uncertainty of the current measuring system, the preliminary experiment results are in accordance with the assessment by finite integration technique which has been carried out.
