Development of Wireless Electric Field Mill for Atmospheric Electric Field Observation [PDF]

TELKOMNIKA (Telecommunication Computing Electronics and Control), 2014
Rotating-vane electric field mill (REFM) sensor is one of the popular methods to measure atmospheric quasi-static electric field. Lightning incident occasion can be predicted by observing electric fields strength in atmosphere. In this paper an integration of REFM with an online wireless data monitoring system for long distance observation and data ...

Investigation of a Micromachined Electric Field Mill Using Dielectric Shutter

Procedia Engineering, 2014
AbstractThis paper investigates a new type of micromachined electric field mill (MEFM) fabricated using a silicon dielectric shutter. The performance of the MEFM is investigated as a function of the dimensional parameters for shutter perforation repetition period, width of perforations and electrodes, shutter thickness, and the gap between shutter and ...

ON THE MILL TYPE ELECTRIC FIELD METER [PDF]

ON THE MILL TYPE ELECTRIC FIELD METER
A mill type electric field meter with high time response has been constructed to measure the electric field change due to lightning discharge. Alternating voltage proportional to the field is produced by the mill consisted of sixty inductive electrodes and a rotary disc. The voltage is amplified and then fed into three recorders.

Isotropic Irradiation Model from Atmospheric Discharges Using Local Atmospheric Electric Field Data

Brazilian Archives of Biology and Technology, 2022
Using a local atmospheric electric field sensor network (Field Mill), an electromagnetic link model was proposed considering a free space electric field and a theoretical electric field calculated from an atmospheric discharge. With this, it was possible

The electrical activity of Saharan dust as perceived from surface electric field observations [PDF]

Atmospheric Chemistry and Physics, 2021
We report on the electric field variations during Saharan dust advection over two atmospheric remote stations in Greece, using synergistic observations of the vertical atmospheric electric field strength (Ez) at ground level and the lidar-derived ...

Investigation of a micromachined electric field mill to maximize the electrostatic field sensitivity [PDF]

, 2012
This thesis includes the modification and optimization to an electric field mill based on micromachining technology. The sensor was originally designed to overcome the disadvantages of the conventional macroscopic field mill. Although it achieved all these listed above with a minimum detectable field strength at 42 V/m, some drawbacks are yet to be ...
