The Design, Test and Evaluation of a Miniaturized Electric Field Meter

The principle of operation of a field mill is explained and analytical analysis of the fixed conductor field mill is presented. Several previous field mill designs are reviewed, and the summary presents the different field mill designs in tabular form. A fixed conductor field mill is designed to operate in a subsonic wind tunnel whose airstream contains a particulate suspension. Various field mill vane configurations are designed, calibrated, and evaluated with the configuration best suited to the environment used to obtain measurement of the magnitude and polarity of the electric field in the wind tunnel
