摘　　要：介绍了精密测量同步电机信号的硬件电路 ,它能将电机故障信息存到RAM区 ,并提供与PC机的接口 ,还能通过CRT实时动态显示同步电机稳态运行信息 ,如三相电流、三相电压及三相功率 .此电路具有很高的可靠性和实用性 .由于采取多种措施来提高精度 ,系统总精度达到 0 1% .A detecting system with high accuracy is designed for synchronous generators,the transient signals are saved as quickly as possible to the expanded RAM and the data can be sent to PC by an interface.Steady signals can show lively and dynamically by CRT.When the generators break down,one will be warned of the accident by the detecting system with sound and light.The system possesses high stability and practicability.Several means are used to ensure its accuracy.The whole accuracy of this system is up to 0.1%.
