Abstract :
We present the potentialities of electro-optic sensors to perform non-invasive and vectorial electric field measurement. The realized optical probes are dedicated to the diagnostic of high voltage equipment regardless of magnetic field and temperature variations. The performances of such a technique are characterized and are compared to more commonly used sensors. The optical and pigtailed transducer is here used to perform the non invasive electric field mapping within a coaxial structure. Latest improvement concerning sensitivity enhancement are also investigated.
