CT Analyzer
Current transformer testing, calibration and assessment
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
