Calibration Technology of Low-frequency Electric Field Strength Basing on the Method of Standard Field
摘要
Abstract
In order to realize the calibration of low-frequency electric field measuring instrument,the low-frequency electric field measurement technology based on the standard field method is discussed.The structure and the working principle of the field meter is given,the method of generating the calculable standard electric field by parallel plates is analyzed,then the calibration system is built.The system is applied to carry out calibrating experiment,the sources of error are analyzed,and the uncertainty of measurement result has been evaluated.Another method basing the TEM cell is applied to verify the calibration result,and the comparison data shows that the calibration result of this calibration system is acceptable and reliable,which meets the calibration requirements of typical low-frequency electric field measuring instruments.关键词
