Abstract

Nowadays, electric fields above the ground are measured mainly by so‐called ‘field mill type’ sensor systems. However, their measurements are limited to vertical field component only due to its technical constraint. Out of necessity of measurements of electric field components in arbitrary directions in any spaces, a linear dipole type DC electric field sensor system, which can be immersed within a fully uniform electric field, was developed. However, it had been remained unknown whether its sensor output is parameter‐dependent or not, and unknown whether it can provide reliable intensity value of measured electric fields or not. In order to clarify these points, test observations of natural electric fields have been conducted by means of plural sensor systems having different values of parameter. Obtained electric field intensity derived from the observed data has shown a parameter‐dependence despite that it should be constant for any parameter values. After a detailed analysis of the effect of the parameter along the equivalent electric circuit of the sensor system, a field‐calibrating formula, which can make the sensor system to be parameter‐independent, has been found. Finally, the linear dipole type DC electric field sensor system for obtaining reliable electric field intensities has been established. © 2024 The Author(s).

利用线性偶极子传感器系统建立直流电场测量系统

目前，地面电场主要由所谓的 "场磨式 "传感器系统测量。然而，由于技术限制，其测量仅限于垂直方向的电场分量。出于测量任意空间任意方向电场分量的需要，人们开发了一种线性偶极子型直流电场传感器系统，它可以浸没在完全均匀的电场中。然而，它的传感器输出是否与参数有关，是否能提供可靠的测量电场强度值，一直是个未知数。为了澄清这些问题，我们通过具有不同参数值的多个传感器系统对自然电场进行了测试观测。从观测数据中获得的电场强度与参数有关，尽管任何参数值下的电场强度都应该是恒定的。在详细分析了参数对传感器系统等效电路的影响后，我们找到了一个场校准公式，它可以使传感器系统与参数无关。最后，建立了可获得可靠电场强度的线性偶极子型直流电场传感器系统。© 2024 The Author(s).IEEJ Transactions on Electrical and Electronic Engineering 由日本电气工程师学会和 Wiley Periodicals LLC 出版。
