Abstract
The article reviews the method of measuring the electric field strength by the average value. Its advantages and disadvantages are discovered. Taking into account the identified disadvantages an improved method using a dual sensor and a built-in measuring and computing device, which allows to directly obtain the result of measuring the electric field strength, is proposed. To carry out the improved method of measurement in the devices for measuring the electric field strength, various types of electric induction sensors are considered from the position of minimum error and suitability for the improved method, of which dual sensors are selected. The use of dual sensors and the improved method in the proposed devices for measuring the electric field strength makes it possible to reduce the measurement error to +- (2-5) %. The designed devices for measuring the electric field strength allow obtaining the measurement result in the form of an equivalent of the electric field strength of a point charge.
