【Abstract】 For large generators striken by fast transient overvoltage, based on real time data of the fast transient overvoltage and finite element method with image technique, the insulation safety state of large generators can be analyzed, predicted and monitored on line. The on line insulation diagnosis method of large generators has higher practicability, and the application of the method is presented when it is used to protect large generators against the fast transient overvoltage.更多还原
