Abstract :
This paper presents details of a compact 132 kV insulator arrangement developed for use with unlinked optical voltage and current transducers (OCT and OVT). The measured temperature characteristics of terbium gallium garnet, the Faraday rotator in the OCT, is given and compared to previously published results. The application of this data to a temperature compensation system for the OCT is discussed. In addition, research results associated with the identification of piezoelectric resonance in the OVT is presented and a solution proposed and tested
