【Abstract】 In order to meet the requirements for small size, automation and high reliability of protection and monitor equipment in electric power system, an Optoelectric Current Transformer(OECT) is designed. The OECT consists of optic fiber, communication unit and microcomputer, and it can be applied to current measurement, harmonic wave analysis and power measurement. The trial run in power network demonstrates that the OECT has the advantages of wide dynamic measuring range, fast response speed and resistance of electromagnetic interference.更多还原
