CT analyser Brief Introduction

This portable Automatic Current Transformer Testing Equipment CT PT Analyzer allows performing many different measurements such as saturation, ratio and polarity tests and CT winding resistance test. Substation maintenance and commissioning test equipment, CTA-1000 Series CT Analyzer is extremely appreciated by electrical engineers for its high accuracy and portability.

Main Technical Data

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

Additional features:

• Simulate different burdens and currents

• Analyze the effect of CT saturation

• Measure VT ratio

• Multimeter

Key features

• Highest measurement accuracy: 0.05 % / 2 min when calibrating on site

• Very small and lightweight (<9kg /19.8lbs), 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 < 2min)

• Excellent workplace safety - Tests run at max. 180 V
