Abstract
The authors describe the design[, assembly[, and testing results for prototypes of an optical current transformer (CT) and a voltage-dividing-type voltage transformer (PD). The optical CT and PD were developed to be applicable to three-phase enclosed-type 300 kV gas-insulated switchgear (GIS) and air-insulated 168 kV substation systems. Test results for the newly developed optical CT and PD showed that their basic properties conform with JEC 1201, the Japanese standard for electric-power instrument transformers
