CT Analyzer

Analyze your Current Transformer (CT) with a simple button How the CT Analyzer works

• Injection of weak test signals on the secondary side of the CT
• Determination of the parameters of the equivalent circuit of the CT
• Identification of all relevant TC performance parameters
• Display of all relevant CT parameters and its accuracy at different currents and loads
• TC assessment in accordance with the selected standard
• Determination of unknown TC nameplate parameters
• Demagnetization of the TC after the test

Measuring range

• Phase shift and ratio accuracy
• Winding resistance
• Magnetization characteristics (knee voltage)
• Composite error (ALF, ALFi, FS, FSi, Vb)  Load impedance
• Transient classes and parameters of TCs (TPS, TPX, TPY and TPZ type)
• Transient sizing factor (Ktd)
• If missing/unknown value: CT type, class, ratio, knee point, power factor, rated load, operating load, primary and secondary winding resistance
• Residual flux
• Immediate assessment
