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

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

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 ...

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,

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 ...

On electric and magnetic configurations in the SU(2)-Yang-Mills field equations
Letters in Mathematical Physics, 1984We discuss several field configurations arising from the nonabelian classical field equations of a source-free SU(2)-Yang-Mills system. The 'quasi-gauge' configurations are analyzed and classified according to the solutions of a nonlinear partial-differential equation in two geometrical variables.
