TRT33A Getting Started
When possible vector group is selected, the TRT33A asks to confirm selection.
Undetected vector groups
If it is impossible, either because of some problems inside the transformer under test or due to wrong
cable/clamp connections, for the TRT33A
to detect vector group correctly, the message “Unable to
dete
ct vector group” will be shown on the display.
After this message pressing any key will display the
CONFIGURATION
menu.
Continue of the test
Once the vector group is detected and confirmed, the TRT33A continues with the test.
Results of both true three-phase and single phase tests of the three-phase transformer are displayed. To
view all results, press
DOWN
or
ENTER
.
The display is showing the test results from Test 1 (Reading 01) within Test Record 02.
