This paper illustrate the background of the research on the fault recorder for generator-transformer unit, and the present state of the fault recorder for generator-transformer unit,alsothe new requirements advanced by the power system for it. Embarked on researching thefunction of the fault recorder, combined on the facts of the electric power generationcorporation of Yu-Xin, explain the setting of enable value of the fault recorder, analysis itsenable mode,enable criterion and fault detecting algorithm, explain the new type one'simplement and using by the numbers. Combine the fault occurred in the corporation, thispaper preceded the fault recorder analysis. This paper put forward the theory reference for thefault recorders' design and application...
