| Abstract: | A New active optic-electric current transducer design is developed. The hardware and software of the low-voltage system's signal processing is mainly introduced. The double CPU system is used in the data acquisition and calculation. The result is more accurate by using the arithmetic of smoothing, and the sampling cycle is corrected by detecting the frequencies varying rate, and the protection is realized by detecting sudden change. This system can work well in current measuring, protection and fault recording. |
