Figure 14-7. Test Result Display
a. Description: The ATRT-03/03A/03B displays the transformer winding polarity, turns-ratio,
excitation current (in milliamps) and turns-ratio error percentage. A typical turns-ratio test-result
screen is shown on Figure 14-7 above. The display result is explained below.
Ratio displayed: 15.006
Polarity displayed: “+” (in phase)
Excitation current: 1 mA
Percentage error: 0.04 %
b. Origin: This screen displays after the user presses START on the “Start Test Menu”.
c. Action Option: Press any key to return to go to “Print Test Results” Menu.
Note:
“% DIFF” will only be displayed if nameplate voltages were entered.
