ELECTROMAGNETIC MEASUREMENTS: MEASUREMENT OF THE RMS VALUE OF ALTERNATING CURRENT BY THE METHOD OF EQUAL AND CONSTANT TEMPERATURES

摘要

A method of quickly measuring the rms value of current with electrothermal transducers is examined. High speed is achieved due to the constancy of the temperatures of the transducers during the measurement. The designs of two transducers for measuring rms current are considered and their dynamics and low-frequency error are analyzed.
