摘要
介绍了电场测量传感器的标定原理和方法,进行误差分析并给出提高标定精度的措施。所设计的雷云电场传感器标定电场的范围为10V/m～50kV/m,标定误差小于±5%。在我国目前尚未建立电场专业标准的情况下,通过设计的电场标定系统可对电场传感器进行标定校准,为电场测量数据的准确性提供依据。
The calibration principle and methods of electrical field measuring sensors are introduced, and error analysis and the measures for improving calibration accuracy are stated. The electric field calibrated by the device ranges from 10V/m-50kV/m, with calibration error lower than 5%. In China, professional standards for electric field haven＇t been established and through the development of the electric field calibration system, calibration and alignment of electric field sensors can be conducted, which can provide accurate evidence for electric field measurement data.
