Устройство, реализующее способ из- керени напр женности электрического г ОЛЯ,содержит иcfoчник пол ризованного по эллипсу электрического пол , 20 содержащий две пары пластин 1, Z и 3j, 4, напр жени на которых задаютс сточниками 5 и 6, и измерительную систему с датчиком 7, соединенным с п{риборон 8, к которому подключен ис- 25 т|очник 9 регулируемого переменного напр жени . A device that implements a method for measuring the intensity of an electric g OLA contains a source of an electric field polarized by an ellipse, 20 containing two pairs of plates 1, Z and 3j, 4, the voltages of which are specified by source 5 and 6, and the measuring system with sensor 7, connected to the device {riboron 8, to which is connected a voltage of 25 tons | full-time student 9 of an adjustable alternating voltage.
Способ измерени напр женности электрического пол осуществл етс следующим образом.30The method of measuring the intensity of the electric field is carried out as follows.30
Датчик 7 помещаетс в точку иссле- |уемого пол . Измер ют фазу потенциала изолированного датчика 7, устанавливают фазу напр жени источника У равной фазе потенциала датчика 7, а затем, регулиру величину напр жени источника 9, устанавливают потенциал экрана прибора 8 равным потенциалу изолированного датчика, после чего измер ют напр женность электрического пол .Sensor 7 is placed at the point of the field to be studied. The potential phase of the isolated sensor 7 is measured, the source voltage phase is set to the equal potential phase of the sensor 7, and then, by adjusting the voltage value of source 9, the potential of the screen of the device 8 is set to the potential of the isolated sensor, after which the voltage of the electric field is measured.
Так как в потенциале экрана прибора 8 учтено изменение фазы после перемещени датчика 7 в поле, вли ние пол ризации оказываетс учтено и в измер емое поле датчиком 7 искажений не вноситс , что приводит к повьшению точности измерений.Since the potential of the screen of the device 8 takes into account the phase change after moving the sensor 7 into the field, the effect of polarization is taken into account and the sensor 7 is not distorted into the measured field, which leads to an increase in the measurement accuracy.
