METHOD OF MEASURING STRENGTH OF ELECTROSTATIC FIELD Russian patent published in 2018 - IPC G01R29/12 G01R23/18 

FIELD: measuring equipment.

SUBSTANCE: invention relates to the measurement of electric fields and can be used to measure the intensity of permanent electric fields created both by industrial and laboratory objects and by objects in the atmosphere. In the proposed method for measuring the intensity of an electrostatic field, a spectral analysis of the signal received from the sensor, for example an antenna placed in an electrostatic field, is performed. In addition, spectral analysis of the background electromagnetic field obtained from the antenna placed outside the electrostatic field is additionally carried out. After that, the spectral characteristics of the first and second antennas are compared and the magnitude of the electrostatic field strength is judged by their difference.

EFFECT: technical result is improved accuracy of measuring the strength of the electrostatic field in the presence of electromagnetic interference.
