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 ...

Limitations on the performance of ‘field mill’ fieldmeters with alternating electric fields
Journal of Electrostatics, 2015Abstract 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

IEEE Power Engineering Review, 1983
The electric environment under HVDC transmission lines is characterized by electric field, current density and space charge density. The measurement of electric field at and above ground level is described in this paper. A field-mill instrument has been developed for ground-level measurements and has been used extensively under the bipolar dc test line

Design, implemetation and calibration of electric field mill
2016 3rd Conference on Power Engineering and Renewable Energy (ICPERE), 2016The 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 ...

Electric and Magnetic Fields at Three Pulp and Paper Mills
AIHAJ, 1994Extremely low frequency (60 Hz) electric and magnetic field levels were measured at three Canadian pulp and paper mills, using area point-in-time measurements. Most electric field levels were below the limit of detection of 1 V/m (92 of 132 measurements); the highest measured field was 47 V/m. Measured magnetic field strengths ranged from less than the

Differential mill for measuring electric fields and conductivities in thunderclouds
pure and applied geophysics, 1970A differential rotating mill for the measurement of electric fields has been designed and built. The instrument was specifically designed to be insensitive to the effects of space charge and frictional charging so that it could operate in the environment of an active thundercloud. The electric field range of the device is 100 to 250,000 volts per meter,

Design and Fabrication of a Field Mill for Ground-Level Electric Field Measurement
Journal of the Korean Institute of Illuminating and Electrical Installation Engineers, 2007A field mill capable of measuring the magnitude and polarity of electric fields at the ground level was studied to apply to a lightning warning system as a sensor. We designed and fabricated a planar-shutter type field mill with a rotating-vanes. A calibration of the field mill was performed in a vertically symmetrical arrangement which consists of two

Thunderstorm tracking system using neural networks and measured electric fields from few field mills
2005 IEEE International Symposium on Circuits and Systems, 2005The paper presents a novel system to asses quickly the direction of thunderstorm by using a few field mills on the ground. As opposed to traditional methods using expensive radar systems to detect thundercloud movement, the presented method simply uses the electric waveforms detected by the field mills and, by using a neural network of suitable ...
