Abstract

This paper evaluates the design and testing of an optical voltage transformer (VT) using a fiber Bragg grating (FBG) and a PZT ceramics stack. The application is directed to the power industry to measure voltage in high-voltage distribution lines and can be used as the core of a practical 13.8 kV-Class VT. The sensor consists of a stack of ceramic rings spaced by thin copper discs and an FBG sensor attached to an aluminum support where the stack is fixed. Experimental results indicate linear relationship between voltages applied to the sensor and the displacement of reflective spectrum of FBG in high voltage applications.
