This paper describes a novel voltage transducer. Its design is based on a mathematical procedure that enables a small number of strategically positioned electric field sensors to accurately measure the voltage. The voltage transducer takes advantage of existing compact, non-intrusive optical electric field sensor technology, specifically, the integrated-optic Pockels cell (IOPC), but is not limited to optical technology. The key advantage of this voltage transducer over other existing optics-based voltage transducer technologies is that it does not require any customized electrode structures and/or special insulation. A high-voltage integrated-optic voltage transducer has been used to obtain measurements with metering class accuracies.
