Current testing device CT Analyzer

voltageelectricquality

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
