Figure 64.0 Test Plan Test Results Status Display
a. Description: The single phase test results of the measured transformer turns-ratio,
excitation current, percentage error, and “PASS/FAIL” (i.e., P for pass, F for fail) status is
displayed for this test. The three phase test results are displayed first, then the phase
information for A (i.e., H1-H3, X1-X3 phase difference), B (i.e., H2-H1, X2-X1 phase
difference), and C (i.e., H3-H2, X3-X2 phase difference). The single phase test results are
displayed last. The single phase differences are: A (H1-H3, X1-X0), B (H2-H1, X2-X0),
and C (H3-H2, X3-X0).
b. Origin: This menu is displayed after the TRI-PHASE™ performs a test plan test.
c. Action To Perform: Press any key or push down the Control Knob to advance to the
“Print Test Results Menu”.
NOTE:
“PASS” or “FAIL” status is shown as “P” or “F” next to the “%DIFF” test result for A, B, and C.
The Pass and Fail results are based on the % difference. If the % difference is less than the preset
value, the “P”(Pass) is displayed. If the % difference is greater than the preset value, the “F”(Fail)
is displayed.
