Abstract
Measuring the AC and DC hybrid electric field is significant for the electromagnetic environment evaluation and for the design of AC/DC hybrid transmission lines. In this paper, a measuring method for both DC and AC electric field measurement by the integrated optical electric field sensor was proposed. The DC electric field can be measured by rotating the sensor by a servomotor which modulates the DC signals into AC signals. A measuring system was implemented and calibrated. A field measurement under an AC/DC hybrid transmission line in Jeju Island, Korea was carried out, and the measured data of the electric field under different DC operating modes were obtained. The results obtained by the proposed method were in reasonably good agreement with a commercial AC probe and the computed DC electric field.
