英文摘要：

In order to satisfy the demands of high voltage transducer in modern power industry, designing a novel optic fiber high voltage transducer is focused on. Based on the converse piezoelectric effect of quartz, a novel dual-mode interferometric electronic voltage transformer is presented and the primary theory is investigated. The capability of voltage transformer is improved by the two step models interferometric theory, for avoiding environment interfere, the theory bases of improving system measurement precision is offered; the transducer probe is analyzed and investi gated by using software of finite element methodology. The result shows that the transducer probe will not breakdown at peak voltages and contents the demand of project, which can provide a theoretical foundation for stability of voltage measurement. The sensing and transmission of signals are all completed by fiber with simple light path, im munity to circumstance, nicety, safety credibility, price low and no pollution. This configuration is a new technique for high voltage transducers design.
