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 ...

The Impact of Filed Mill on the DC Electric Field Calibration
2013 Third International Conference on Instrumentation, Measurement, Computer, Communication and Control, 2013Field mill sensors are widely used in lightning warning, atmospheric electric field measurement, HVDC electromagnetic environment testing and other areas. The calibration of the sensor has a significant impact on the measurements of electric field. Based on the existing structure of the sensor, the analysis of the mutual effect between the sensor and ...

The latest design and development of the field mill used as atmospheric electric field sensor
2009 5th Asia-Pacific Conference on Environmental Electromagnetics, 2009In 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.

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

Inhibition of tomato (Licopersicon esculentum Mill.) pectin methylesterase by pulsed electric fields
Innovative Food Science & Emerging Technologies, 2000High intensity pulsed electric fields were utilized for inhibition of pectin methylesterase (PME) from tomato and a 93.8% reduction of the initial activity was achieved with 400 pulses of 0.02-ms pulse-width at 24 kV/cm. The classical exponential decay model as well as Hulsheger’s and Fermi’s empirical models adequately described the enzymatic ...

Cloud-to-ground lightning warnings based on electric field-mill measurements in Brazil
2010 30th International Conference on Lightning Protection (ICLP), 2010This paper presents a methodology that employs the electrostatic field variations caused by thundercloud formation or displacement to generate lightning warnings over a region of interest in Southeastern Brazil. It was shown that the better critical field threshold is 0.9 kV/m for a encircle area with 10 km radius around the sensor installation. Values
