Click on the 'OK' button. Again, the test and its parameters will appear
in the 'Program' window.
7. Finally, by double-clicking the left mouse button, select 'TR Turns
Ratio' from the 'Available Tests' window.
At the dialogue box, enter the data required for the turns ratio test:
The AT measures the turns ratio between 'primary' and 'secondary' windings;
and allows the possibility of applying the test voltage to a third 'energized'
winding. For this example, the primary and energized windings are the same:
Energized high terminal
Energized low terminal
Primary high terminal
Primary low terminal
Secondary high terminal
Secondary low terminal
Using the default ' % ' type of limits, enter:
