Abstract
This paper researches the modular interference characteristics of polarization maintaining two-mode photonic crystal fiber (PMTMPCF) and proposes a new optical voltage transducer (OVT) for the electric power system based on modular interference in PMTMPCF. which uses a quartz crystal cylinder wrapped with PMTMPCF as the voltage sensing head, modulating the two interference output lobes' intensity of the PMTMPCF by making use of the converse piezoelectric effect of quartz crystal in high voltage end, while in low voltage end, using a PZT which wrapped with a piece of PMTMPCF to adjust the initial phase difference to orthogonal status. The experimental results show that the measurement accuracy can achieve 0.2% with good linearity.
