• Accuracy limit value coefficient(ALF) • Instrument security factor(FS)
Make evaluation for test results according to selected standards Make word report for test result Make word reports one time for multi-group test records on the PC Calculate ratio errors and phase angle errors at rated burden and working burden in one time test Compare excitation curves with saved excitation curves in the same window

Applications

• CT nameplate guess • CT parameters check in work burden • PT routine test

• CT transient parameters analysis • CT ratio and phase error calibration
