FIELD: electricity.SUBSTANCE: device comprises three sensors 1 installed mutually orthogonally. Sensors are rigidly fixed in the body 2 made in the form of a cube. Each sensor 1 comprises one or more toroidal coils of inductance 4 arranged on a current conductor 3, made in the form of a tube, and the coils of inductance are connected in parallel, wound onto circular magnetic conductors 5, current thickeners 6 fixed on the ends of the current conductor 3 and made in the form of rings. The device also includes three electronic units of preliminary processing of signals 7, the input of each one is connected to the output of the appropriate sensor 1, and the output - to the input of a recording unit 8. The inner diameter of the rings 6 is equal to the outer diameter of the current conductor 3, and the outer diameter of rings 6 - to the length of the face 9 of the body 2, besides, the outer diameter of the current conductor 3 is equal to the inner diameter of the inductance coil 4. Current conductors 3, current thickeners 6 and the body 2 are made from a dielectric material. Sensors are installed so that their current conductors do not cross with each other.EFFECT: higher accuracy of measurement.4 dwg |
