摘要

This report summarizes the results of an investigation into the technical and economic reasons for improving power system voltage and current measurements, with special emphasis on the prospects for utilizing optical technology. The investigation assesses information from interviews with representatives of utilities and manufacturing companies, along with other information from published sources. According to interviewees, the shortcomings of the established technology and the claimed advantages of the new one do not warrant an immediate switchover to new technology. However, there was also a consensus among those interviewed that a long-term trend toward the optical measurement systems has begun and that optical measurement technology will ultimately be used in the power grid. Measurement system needs were: lower cost alternatives; greater dynamic range for current transformers; the demand for more accurate metering; fiber optic data transmission which is broadband, very fast, and free from electrical interference, properties which are required by computer-controlled systems, computer control which requires more real time data. The report concludes with a recommendation for a carefully structured and coordinated program of research and development. 43 refs., 3 figs., 3 tabs. (ERA citation 12:047367)
