a. Description: This menu allows the operator to use the transformer nameplate voltages to derive
a calculated turns ratio. This calculated turns ratio is then used to compare with the measured turns
ratio, which produces an error-difference percentage.
b. Origin: Select key 1 or 2 from options listed in Figure 14-4.
c. Action Option: Press key 1 (YES) to use the calculated ratio in the test results and advance to
“Transformer Name Plate Voltage” menu (Figure 14-5). Press key 2 (NO) to bypass this option and
advance to “Start Test” menu (Figure 14-6).
Note:
1. If the user continues to run another test on the transformer, the menu below will be displayed
(Figure 14-4A). The user now has a new option: the same nameplate voltage data can be used.
2. Press key 3 to use the current nameplate voltage and advance to “Start Test” menu (Figure 14-
6).
