Surface discharge is one of the main phenomena in the fault of electric apparatus, but is not cleared yet. The electric field measurement in and around a corona streamer while the surface discharge creeps is greatly helpful for analyzing it. There is optical measurement technique for electric fields by using Pockels crystal, and an optical waveguide technique has been successfully introduced to miniaturize the sensors. The electric field measurement just under the surface discharge is tried with the optical waveguide Pockels sensor installed on a PMMA plate and output signals according to its development are obtained.
