  • Transformer Maintenance and Diagnostics Using Frequency

    Test circuit ground is considered to be the tank of the transformer under test. The traditional technique is to measure and record the exciting impulse and the resulting response current using a digitizer with sufficient amplitude resolution (generally accepted as at least 9 bit, or 1 part in 512 resolution), and sufficient sampling rate to preserve the highest frequency to be included in the transfer function result.

    High Current Transformer is designed as an open type transformer that uses the test object as its secondary coil or has 1 or 2-turn self secondary winding. The conductors cores temperature depends on the short-circuit high current caused by the test object. According to the current going through the test object, the test temperature of the conductor will change.

    This technique by design inserts the current measuring cable impedance in series with the transformer winding under test, thereby making the result highly dependent on the particular length and characteristics of the cable. In addition, the relatively high 50 ohm impedance significantly damps the high frequency portion of the FRA response.
