Abstract

In this paper, we investigate experimentally the performance of a prototype optical voltage sensor utilizing a piezoelectric component and a dual FBG sensor combined with an intesiometric detection scheme. The sensor construction allows for the sensor interrogation using a single photodetector, and by eliminating spectral scanning devices, the measurement system benefits from a significant cost reduction and potentially improved speed of operation. Preliminary voltage characterization reveals that the proposed sensor is capable of reliable ac voltage measurement.
