Abstract

In this article, the basic principle and the key technique of an optoelectronic type of electric current transducer system are discussed. The system is used to measure the primary current in a high-voltage and large-capacity power system.It has many advantages such as wide current range, high precision, simple insulation structure and high price- performance ratio. The signals of electric current at the high-voltage side are converted to digital signals, which are coded according to a special mode and transmitted with a special baud rate. In order to ensure the measuring accuracy, a fast quasi-synchronous weighting algorithm is adopted to do data processing at the low-voltage side.
