    Software TRANSFORMER

    Automatic tests on Power Transformers.

    Categories: ,

    Description

    Is it possible to automate routine tests on power transformers, increasing the reliability and precision of the procedure?

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

    • Transformation Ratio;
    • Transformation Ratio in a three-phase manner;
    • Winding resistance with temperature compensation;
    • Insulation test;

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

    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 case and the tested equipment.

    In the single-phase relationship test, the user must know the connections of the power transformer, in addition to the vector group. Another input information would be the nominal transformation ratio.

    In this test, the user is allowed to register the amount of TAPS that the TR has. With this, the suitcase will test position by position, sending up or down command with a predetermined time by the user

    Another feature that the software has is to allow the user to measure the empty current of the TR while performing a relationship test.

    In the relationship tests, the software by default already performs the procedure at 55 Hz avoiding influences from external inductions.

    If the user wishes, he has the option of performing the relationship test in a three-phase manner. In this case, it is enough to inform the nominal list and the TAP registration for the test to occur. It is not necessary to inform the lag, this information being a response data at the end of the test. Because it is three-phase, the relationship test is performed on a single connection, giving greater automation to the procedure.

    In the winding resistance test, in addition to correcting the resistance value for a reference temperature, the user informs the rated voltages and powers so that the software itself reports the highest current for generation in order not to damage the winding. The aim would be to protect the windings from possible thermal damage.

    In this ohmic resistance test, it is worth noting that the current reaches the test value through a ramp. After reaching a value, the measurement stabilizes and the value is captured, a new ramp is applied to de-energize the core.
