Design, construction, and test of a passive optical prototype high voltage instrument transformer

This paper describes an optical voltage transformer (OVT) for a 132-130 kV system based on the Pockels effect in a Bi4Ge3O12 crystal. Different from the majority of OVTs reported, this construction does not use any capacitive voltage division. To accomplish this, it was necessary to redesign the optical modulator. A prototype of the OVT has been constructed and tested Original language English Journal IEEE Transactions on Power Delivery Volume 10 Issue number 3 Pages (from-to) 1332-1337 ISSN 0885-8977 DOIs https://doi.org/10.1109/61.400913 Publication status Published - 1995 Bibliographical note Copyright: 1995 IEEE.
