A simple method for the characterization of I-V transducers

The paper presents a simple method for the characterization of the current-to-voltage (I-V) transducers that are based on current transformers. It is performed by reducing to a minimum the unbalance voltage that arises when the transducer output is compared with the voltage drop caused by the transducer input current across a precision noninductive shunt. Experimental data relevant to different types of passive and active I-V transducers are reported and discussed in the paper.
