Sensor of the electric field strength vector components in the form of three mutually perpendicular square

Abstract

Abstract The development of instruments for measuring the electric field strength is not a simple scientific and practical task. First of all, this is due to the high metrological requirements that are imposed on sensors of electric field strength. There is a wide variety of electric field sensors of various shapes (cubic, cylindrical, spherical), the principle of action (directional and non-directional reception) and design features (housing, uncased) do not provide the desired metrological characteristics. Therefore, scientific work related to the development of sensors of electric field strength is developing and relevant. The aim of the scientific research is to create a frameless three-axis electric field strength sensor, which would be easy to calculate both for housing sensors, as well as simplicity of design and small mass as for frameless sensors. The constructive sensor created as a result of scientific research represents three mutually perpendicular square dielectric plates. The sensing element bases are square conductive sensing elements. The sensor has a different spatial measurement range and depends on the desired error. A large error correlates with a wider range. For a measurement error of no more than 10%, the maximum possible spatial measurement range will be a = 0.33. Consequently, the minimum possible distance to the field source, at which the sensor error is no more than 10%, will be d = 3L, where L is half the side of the square sensitive element.
