CTA-1000C CT/PT Analyzer

Product Center

 Product Introduction 

CTA-1000 Series CT Analyzer automatically determines all relevant current transformer values and compares the results with the selected standard, include excitation data, saturation inflection point, remanence coefficient, accuracy limit overcurrent factor, ratio and error data. 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:

2. Easy to use. The CT 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. CT analyzer debugging time is short (automatic test duration <2 minutes);

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. The CT analyzer has a professional pull box design that is easy to carry and resistant to vibration.


The following values can be determined using the CT/PT Analyzer:

1. CT:

(1) Accuracy of the ratio and phase angle, taking into consideration the nominal burden and connected burden

(2) CT excitation and saturation

(3) Burden impedance

(4) Winding resistance Saturated and non-saturated inductance

(5) CT polarity

2. PT:

(1) PT excitation and saturation

(2) Burden impedance

(3) Winding resistance Saturated and non-saturated inductance

(4) PT polarity
