Exemplary analog-to-digital measuring device dc converter

Kazakov Mikhail Konstantinovich

The article describes an exemplary high-DC measuring Converter intended for use as a metrological device for checking stationary high-DC measuring converters without dismantling them on-site. The Converter is made on the basis of the Rogovsky belt (air transformer). During the measurement process, the Rogovsky belt from the initial closed state (when located outside the current line) is brought to the busbar package with the measured current until it is completely closed when the package is inside. The signal from the output of the belt is integrated, and it is shown that a voltage is formed at the output of the Converter, which is proportional to the measured current of the bus package.
