CT/PT Analyzer

Type: CTA-1000
    CTA-1000 Series CT Analyzer automatically determines all relevant current transformer values and compares the results with the selected standard. The device evaluates the current transformer as per the IEC or IEEE standard within seconds with the push of a button.  
    It facilitates fast and economical on-site testing and calibration of metering and protection current transformers. Manufacturers of current transformers, high voltage transformers and switchgear also use the CT Analyzer for tests during development and production.

Product Features
1. Wide range of measurements:
    (1) CT:
    • CT ratio and phase-angle accuracy
    • CT accuracy for different burdens
    • CT winding resistance
    • CT excitation characteristics
    • CT inductance (saturated and unsaturated)
    • ALF and FS (direct and indirect)
    • Burden impedance
    • CT residual magnetism
    (2) PT:
    • PT excitation and saturation
    • Burden impedance
    • Winding resistance Saturated and non-saturated inductance
    • PT polarity
    2. Easy to use. The CT PT Analyzer allows all types of single and multi-ratio current transformers to be tested, and it evaluates the current transformer within seconds with the push of a button;
    3. Highest measurement accuracy: 0.05% / 2 min when calibrating on site;
    4. Automatic evaluation according to IEC and IEEE standards;
    5. Short commissioning times (duration of the automatic test<2min);
    6. Excellent workplace safety - Tests run at max. 180V;
    7. Very small and lightweight (<9kg/19.8lbs), easy to transport for on-site testing;
    8. Professional pull box design, easy to carry, anti-vibration.
