Electric Field Mill, an Effective Methodology to Measure the Localized Lower Atmospheric Electric Field

Materials Today: Proceedings, 2020
Abstract Atmospheric electric field is an utmost parameter to study the dynamics of earth’s atmosphere. Response of electric field may give the idea of localized atmospheric agitations. Electric field mill monitoring system monitors the atmospheric electric field variations which help to investigate and characterize the atmospheric variability in ...

Design, implemetation and calibration of electric field mill

2016 3rd Conference on Power Engineering and Renewable Energy (ICPERE), 2016
The efforts to improve the security of a lightning strike is giving a lightning early warning system. One method that can be used to get the warning is to measure the electric field in the atmosphere. Electric field mill (EFM) is an instrument that can be used to measure the strength of electric fields in atmosphere as a result of electrostatic charge ...

Limitations on the performance of ‘field mill’ fieldmeters with alternating electric fields

Journal of Electrostatics, 2015
Abstract The response of field mill type electrostatic fieldmeters to alternating electric fields is limited by the chopping frequency. Measurements reported here show that alternating frequencies at the chopping frequency, and related harmonics, can create confusing low frequency outputs. Hence care is needed for interpreting observations where such

The latest design and development of the field mill used as atmospheric electric field sensor

2009 5th Asia-Pacific Conference on Environmental Electromagnetics, 2009
In this paper, the sensor of a traditional atmospheric electric field mill was optimized. The earthing brush and photoelectricity synchrodetector were removed. A stator with double-electrode difference structure was adopted to produce difference. It was put in a signal acquisition and processing printed circuit board directly.

Electric field mill for the simultaneous measurement of electric field strength and ion current diensity [PDF]

, 1995
In the last 20 years, the use of high voltage direct current (HVDC) power transmission has grown considerably. With the increase in the number of HVDC transmission lines and in the transmission voltages, concern has increased as to possible health effects. For research on these health effects to be carried out, it is necessary to measure the electrical
