Abstract :
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
