摘要
为了实现低频电场测量仪的校准,探讨了基于标准场法的低频电场计量技术。描述了低频电场测量仪的结构和工作原理,分析了应用平行板产生可计算标准电场的方法,研究构建了校准系统。应用该系统进行了校准测量实验,分析了测量误差来源,评估了测量结果的不确定度。将实验结果与应用横电磁波室法的测量结果作了比较,数据表明该校准系统的测量结果合理,满足低频电场测量仪的校准要求。
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.
