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 bewarned 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%.
