Abstract

In this work, an integrated optical waveguide electric field sensor with segmented electrodes is designed and fabricated for measurement of lightning impulse electric field. First, the compositions of the sensing system were described briefly. The calibration of the sensor is taken using an impulse high voltage generator and parallel square electrodes. The maximal detectable electric field range (-75 kV/m to 245 kV/m) is obtained by analyzing the results. Finally, the measurements of the lightning impulse electric field are given. As a result, the integrated optical electric field sensor is suitable for lightning electric field measurement investigation.
