Abstract :
This paper presents the development and characterization of a fiber optic transducer based on lossy mode resonances (LMRs) to monitor current transformers in high voltage networks. A multilayer structure was created in order to generate and to shift the LMR peak by an electro-optic material deposited between two electrodes. Three devices of different sensitive layer thickness have been compared and resonance wavelength displacements greater than 200 nm have been achieved, what makes this device suitable for current monitoring.
