CPC 100 V1.414 - 12Test settingsFigure 8:CTBurden test cardwith test resultsNavigate to the parameter fields, and enter the values according to your testrequirements:Selecting the check box "Manual input" lets you enter the value for Vsecmanually, for example, when Vsec was measured with an external volt meterrather than at input V1AC.MeasurementsIsec: nominal secondary currentItest: secondary injection current from 6A AC outputf: output frequencyAuto select check box for automatic test (default), clear for manualtest (refer to page 4-13).Isec: actual secondary current, measured via input IACVsec: secondary voltage at the burden, measured at input V1AC,and phase angle ϕ relative to IsecBurden: burden in VA: Isec nom × (Vsec act × Isec nom/Isec act)cosϕ cosine of phase angle ϕ
