Test Item

The software provides four kinds of test items, they are Ratio Control Boundary Search, Ratio Restraint Setting Point Search, Harmonic Restraint Boundary Search and Harmonic Restraint Setting Point Search. Ratio Restraint Boundary Search stands for that all action boundary of whole differential protection will be found out, which is the search of the whole action curve of protection; Ratio Restraint Setting Point Search stands for that searching the action state of certain important point ,observing whether the action of this point is correct;the search aim of Harmonic Restraint Boundary Search and Harmonic Restraint Setting Point Search are the same as that of Ratio Control Setting Value Search, which includes searching the boundary of the whole action of harmonic and the protective action of certain setting point.
