Abstract

In this paper, we present an optical electric field and voltage sensor system having features that allow for reliable and very accurate measurement of electric fields and voltages in a HV environment. It is designed to meet the most stringent accuracy requirements of IEC or IEEE/ANSI standards for revenue metering over a wide temperature range and under varying input light intensity. The optical electric field sensor (EFS) system is based on a Pockels cell. The light source, the detection unit, and the processing unit are made of electronic (and opto-electronic) components and are integrated in a single electronics module. Optical fibers effectively guide the light between the electronics module and the sensor-head in the high voltage environment and provide galvanic isolation between these environments.
