The concept of creating an electric field strength meter with the determination of the error of the measurement result and the distance to the field source

Abstract

A new concept of constructing an electric field strength meter is considered. The concept lies in the fact that along with the measurement of the modulus of the electric field strength vector, the error of the measurement result and the distance to the field source are subject to simultaneous instrumental determination. The field meter is based on a new dual sensor and a method for measuring the electric field strength. The ability of the measurement method to determine the error and the distance to the field source is provided by a dual electroinduction spherical sensor. A feature of a dual sensor is the ability to simultaneously output two field strength values measured at one point, obtained with errors of different signs. This feature made it possible to obtain the measurement result as an average value and two measured values, and thereby reduce the measurement error. The presence of two simultaneously measured values of the field strength also made it possible to obtain an empirical formula for determining the relative distance to the source at each measurement point. The obtained values of the relative distances made it possible to determine the error of the measurement result and the distance from the center of the sensor to the field source using known formulas. The possibility of a field meter to simultaneously instrumentally determine the error of the measurement result and the distance to the field source is considered for the first time.
