DEVICE FOR DETERMINING THE INDUCTION OF AN ELECTROMAGNETIC FIELD Russian patent published in 2021 - IPC G01R33/28 

FIELD: electrical measurements.

SUBSTANCE: invention relates to the field of electrical measurements and can be applied to determine the induction of an electromagnetic field inside the cell of a complete switchgear for indoor and outdoor installations with a voltage of 6-10 kV. The claimed device contains three measuring coils connected by terminals to the EMF recorders, a movable platform associated with the measuring coils that can be moved relative to the platform, the first three current transformers, a three-phase voltage regulator connected with the first cable to a three-phase switch, a three-phase load transformer, recorders current connected by means of the second wires to the first current transformers, all measuring coils are installed on a platform, which at the initial position is located on the frame of the withdrawable trolley of a high-voltage circuit breaker, with longitudinal and transverse slots, and a screw nut, limited in the maximum permissible position by rigid rings, and the first threaded axle are designed to ensure the movement of the measuring coils.

EFFECT: ensuring the possibility of measuring the magnetic field strength inside the switchgear cubicle.
