    Is it possible to automate routine tests in CT’s, increasing the reliability and accuracy of the procedure?

    With the CT software, combined with the CE-7012 or CE-7024 hardware, the following tests can be performed:

    • Current Transformation Ratio;
    • Transformation Ratio (using tension);
    • Transformation Ratio for Rogowski coil;
    • Transformation Ratio for low power;
    • Burden or Cargo;
    • Survey of the Magnetization Curve;
    • Winding resistance with temperature compensation;
    • Insulation Test (leakage current check);
    • Polarity Test;
    • Demagnetization routine;

    Developed to perform manual and / or automatic tests on current transformers, the “CT” software allows the simultaneous generation of current and / or voltage signals and the measurement of current and / or voltage signals to assess the correct functioning of the CTs.

    In it, the user defines, for each signal, a generation channel and a measurement channel according to the configuration of the test equipment. This software is only compatible with the CE-7012 and CE-7024.

    With this tool, combined with the characteristics of our hardware, the user will be able to fully automate fundamental tests that were previously carried out in an archaic and inaccurate way. Not counting the post-test where reports can be created automatically. Another important detail is the fact that the software is simple to handle. In it, the user will find connection diagrams to facilitate the connection between the test set and the tested equipment.

    In the relationship tests, it is possible to extract the polarity from the CT and the software by default already performs the procedure at 55 Hz (can be changed, if the user wants to), avoiding influences from external inductions.

    In the burden tests, the user chooses the form of evaluation, whether through knee tension or the installed power of cables.

    To raise the saturation curve, one can choose which standard will validate the knee, which are: IEC / BS, ANSI 45 ° or ANSI 30 °.

    In the winding resistance test it is also possible to compensate for the temperature when the test was carried out to a reference temperature. (automatic copper compensation)

    Finally, there is a demagnetization routine, which allows the user to use it if he wants, without the need to run the curve lifting test.

    In all tests there is the possibility of working with automatic switching of scales, further optimizing the procedure and increasing the reliability of the final analysis.
