Abstract
In order to eliminate the distortion influence error caused by human body on the measurement of hand-held high voltage power frequency electric field measurement device, field intensity distortion caused by induced current of human body has been analyzed, and the enhancement factor of the electric field intensity is introduced to reduce the distortion degree of electric field measurement value by electric field measuring instrument. A simple model of the human body is built, the Ansoft Maxwell is used to simulate and calculate the electric field distribution around the high voltage power frequency transmission lines when human body presented, and distortion influence of field intensity distribution caused by human body has been analyzed. In addition, the enhancement factor value of electric field is determined and the electric field distortion is corrected by experiment and comparing the measurement data with the electromagnetic field analyzer EFA300. With the actual measured values of instrument restored the value of the field intensity when the human body away from the measuring equipment, the distortion influence measurement error can be reduced and measurement precision can be improved.
