Analyze your current transformer (CT) with the push of a button
How CT Analyzer works
» Injects low test signals into secondary side of the CT
» Determines the CT‘s equivalent circuit parameters
» Identifies all relevant CT performance parameters
» Displays all relevant parameters of the CT and its accuracy at different currents and burdens
» Evaluates the CT according to the selected standard
» Determines unknown CT nameplate parameters
» Demagnetizes the CT after the test.
Range of measurements
» Ratio and phase accuracy
» Winding resistance
» Excitation characteristics (knee points)
» Composite error (ALF, ALFi, FS, FSi, Vb)
» Burden impedance
» Transient CT classes and parameters (TPS, TPX, TPY and TPZ type CTs)
» Transient dimensioning factor (Ktd)
» If missing/unknown: CT type, class, ratio, knee point, power factor, nominal burden, operating burden, primary and secondary winding resistance
» Remanence and residual magnetism
» Immediate good/bad evaluation
Additional features
» Simulate different burdens and currents
» Analyze the effect of CT saturation
» Measure VT ratio
» Multimeter
Key features
» Highest measurement accuracy: 0.02 % / 1 min when calibrating on site
» Very small and lightweight (< 8 kg / 17.4 lbs), easy to transport for on-site testing
» Automatic evaluation according to IEC, IEEE and to customized or local/national standards
» Short commissioning times (duration of the automatic test < 1min)
» Excellent workplace safety - Tests run at max. 120 V
» Integration into testing routines using Remote Interface Control
