Research Mineral Product Intelligence Digit Relay Based on AT89C51

Digital relay works on the basis of the discussions in this article, with emphasis on real-time measurement of voltage, current, power point calculation for detailed analysis, after a single treatment system for real-time protection. The digital relay has voltage functions and amperage examination, fault recognition and protection, warning function, with superior machine correspondence and so on. It may carry on the trigger voltage, the starting current hypothesis. After the experiment indicated that the digital relay may realize electric circuit＇s non-electric are, the non-shocking operation, the real-time monitoring after switch＇s voltage, the amperage. It enhances the safety performance which uses electricity and demonstrates the digital relay＇s high performance.
