Пристрій для вимірювання електричного струму

Abstract

The proposed device for measuring electric current contains an analog-to-digital converter, a microprocessor control unit, a digital-to-analog converter, a current transducer based on the Hall effect, a controlled potentiometric voltage divider, and a personal computer. The inputs and outputs of the analog-to-digital converter and the digital-to-analog converter are connected to the corresponding inputs and outputs of the microprocessor control unit. The current transducer is inserted in series in the circuit of the current to be measured. The output of the current transducer is connected to the corresponding input of the analog-to-digital converter via the voltage divider.
