Abstract
Thus far, despite the development of electric field sensors (EFSs) such as field mills, optoelectronic EFSs and microelectromechanical system (MEMS)-based EFSs, no sensor can accurately measure an electric field in space due to the existence of space charge and the influence of charge attachment. To measure a spatial synthetic electric field in an ion flow field, a double potential independent differential EFS based on MEMS is proposed. Compared with other EFSs, this method has the advantages of independent potential (without grounding) and the ability to support the measurement of the synthetic ion flow electric field in space. First, to analyse the charge distribution after the sensor is involved exposed to an electric field, a simulation model was constructed. Then, given the redistribution of the spatial electric field in space and the influence of the surface charge on the sensor, the quantitative relationship between the electric field to be measured and that measured by the proposed sensor was obtained. To improve the performance of the EFS, a set of synthetic field strength sensor calibration systems that consider spatial ion flow injection was established. Furthermore, the parameter λ, which is related to the relative position of the differential chips, was determined. Finally, a series of comparative experiments indicated that the differential EFS highlighted in the present study exhibits good linearity and accuracy.

Summary
With the industrial developments and improvement in living standards, the demand for electricity has increased, and high-voltage, direct current (HVDC) transmission lines have been widely developed worldwide because of their advantages of long transmission distance, large transport capacity and low cost. Studies on synthetic electric field problems in HVDC transmission lines have mainly been conducted using ionized-field numerical calculations and measuring methods or devices. ToTo measure thethe space synthetic electric field inin the ion flow, wewe designed double-potential. To measure the space synthetic electric field inthe the ion flow, we designed double-potential measurement independent based onon technology. TheAs ion flow, we designed a double-potential the measurement ofspace the synthetic electric field inin space. Based on measurements inthe the electrostatic field, we deduced the relationship between the output voltage and the electric field. EFSs based on processing technology consist driving part, as a wider frequency band is supported by smartphones, radio-frequency (RF) MEMS devices have sensing part and a spring part [23]. If the inducted charge on the sensing electrode is detectable, the electric field can be determined.
