Figure 17.0 Transformer Nameplate Voltage Menu
a. Description: This menu provides access to the “Name Plate Voltage” status display
(Figure 18.0) for entry of the transformer nameplate voltages which are used to derive a
calculated turns-ratio. The calculated turns-ratio is then used to compare the measured
turns-ratio and calculate a percentage error reading.
b. Origin: The transformer nameplate voltage menu displays after selecting “Single Phase”
from options listed in the “Transformer Configuration Selection Menu” (Figure 15.0). For
other transformer configurations, this menu displays prior to the “Start/Stop Test” status
display.
c. Action Options: Press key number 1 (“YES”) push down the Control Knob to use the
calculated turns-ratio in the test results and advance to the “Name Plate Voltage” status
display (Figure 18.0). Press key number 2 to bypass this option and advance to the
“Start/Stop Test” status display (Figure 22.0). Selection may also be made by turning the
Control Knob to select a menu option, then pushing down on the Control Knob once the
selection is made.
d. Action To Perform: Select menu option 1 for this example.
