management, where the first grade is name of substation, the second grade name of transformer, the
third grade category and number of transformer winding and the last grade existing data. Data name is
displayed in the manner of “data type @ test time”. Data displayed in the part matches with content of
the label in area (A). When “amplitude-frequency curve” is displayed, the data selection area displays
test result of the amplitude-frequency curve and when “phase-frequency curve” is displayed, the data
selection area displays test result of the phase-frequency curve.
When “amplitude-frequency curve” or “phase-frequency curve” is displayed, the test result is
