Abstract

An optically isolated microminiature electric field sensor based on the Franz-Keldysh effect in gallium arsenide is described. The sensor is suitable for a variety of high-voltage remote sensing electric utility applications, such as field mapping in substations, power line voltage measurement and voltage calibration of high-voltage laboratory diagnostics. Data demonstrating absolute calibration of the field sensor at electric fields in GaAs as low as 5 kV/cm is presented. A system that eliminates temperature drift during line-frequency measurements is described.
