摘要：

The optical instrument transformer is a current and voltage measuring system based on Faraday and Pockels effects, whose principles differ from those of conventional industrial transformers. In principle, this transformer is excellent in such aspects as control of electromagnetic induction noise, rationalization of electrical insulation, and extension of dynamic ranges and frequency bands. By making use of such excellent properties, it is possible to achieve higher performance, higher compactness, and higher reliability of instrument transformers. This paper deals with the designing, assembling, and testing results of a prototype of an optical current transformer (CT) and that of a voltage dividing-type voltage transformer (PD). The optical CT and PD were developed to be applicable to 3-phase-enclosed-type 300kV gas-insulated switchgear (GIS) and air-insulated 168kV substation systems. Test results for the newly developed optical CT and PD showed that their basic properties conform with JEC 1201, Japanese standard for electric-power instrument transformers. © 1990 IEEE
