DIGITAL ELECTRIC CURRENT METER Russian patent published in 2019 - IPC G01R27/00 G01R19/25 

FIELD: physics.

SUBSTANCE: present invention relates to the field of information and measuring equipment. Essence of the claimed solution lies in the fact that a digital electric current meter containing a primary transducer in the form of a fixed coil and a moving coil located on an axis, the recorder and the first source, introduced the second source, large-scale amplifier, analogue-to-digital converter, transformer converter, which includes the first and second fixed windings and a moving winding rigidly fastened to the axis of the moving coil of the primary converter, the recorder is designed as a digital reading device, the output of the first source being connected to the fixed and movable coils of the primary converter, the output of the second source is connected to the first fixed winding of the transformer converter, second fixed winding of the latter is connected via a large-scale amplifier to the input of an analogue-to-digital converter, the output of which is connected to the input of a digital reading device.

EFFECT: technical result of the proposed technical solution is to improve the measurement accuracy.
