“…Sensor is a key part of the electric field measurement system. Now, electric field sensors have been built that permit the electric field to be measured, but most of these are built for atmospheric investigations, voltage meter, and lighting alarm [4–7]. Only few sensors have been used to measure the electric field under HVDC transmission lines.…”

A wireless sensor network-based distributed measurement system is designed for collecting and monitoring the electric field under the high voltage direct current (HVDC) transmission lines. The proposed system architecture is composed of a group of wireless nodes connected with electric field sensors and a base station. The electric field sensor based on Gauss's law is elaborated and developed. For the design of wireless node, the ARM microprocessor and Zigbee radio frequency module are employed. The proposed system has been used in China's state grid HVDC test base and the in situ power transmission projects. Based on the experimental results, the proposed measurement system demonstrates that it can adapt to the complex electromagnetic environment under the transmission lines and can accomplish the accurate, flexible, and stable demands of the electric field measurement.

“…The field mill is according to Gauss's law to measure electric field [4], which states that the electrical flux out of a closed surface is equal to the charge enclosed divided by The structure of field mill is shown in Fig.1. The motor drives the earthed screen electrode (rotor) rotating, and the sensing electrode (stator) is exposed and screened from the electric field E by the rotor periodically.…”

Experimental studies are reported that measuring results of electric field mill are inconsistency, which affects their measuring accuracy. This paper introduces the principle of electric field measurement. Statistical analysis of calibration experimental results shows that measurement data obey normal distribution rule. Correlation analysis result indicates that the distance between two electrodes of field mill has a strong linear correlation with measure results. Linear model is established with the method of regression analysis. Finally, residual test verify the rationality of regression model.

An Electric Field Microsensor with Mutual Shielding Electrodes

et al. 2021

This paper proposes an electric field microsensor (EFM) with mutual shielding electrodes. Based on the charge-induction principle, the EFM consists of fixed electrodes and piezoelectric-driving vertically-movable electrodes. All the fixed electrodes and movable electrodes work as both sensing electrodes and shielding electrodes. In other words, all the fixed and movable electrodes are sensing electrodes, and they are mutually shielding electrodes simultaneously. The movable electrodes are driven to periodically modulate the electric field distribution at themselves and the fixed electrodes, and the induced currents from both movable and fixed electrodes are generated simultaneously. The electrode structure adopts an interdigital structure, and the EFM has been simulated by finite element methods. Simulation results show that, since the sensing area of this EFM is doubled, the variation of induced charge is twice, and therefore the output signal of the sensor is increased. The piezoelectric material, lead zirconate titanate (PZT), is prepared by the sol–gel method, and the microsensor chip is fabricated.
