1st Voltage:
Transformer rated voltage of high voltage side
2nd Voltage:
Transformer rated voltage of low voltage side
Total tap number:
The total number of tap points for multi-tap transformer. If
it's not a multi-tap transformer, total tap number should be set as 1 (initial value 1).
Tap distance:
the adjustment percentage of each tap ratio, e.g. 1.25%, then 1.25
should be entered.
Connection group:
Select the transformer wiring methods such as: Y / y \ D / y,
ZN / y, etc. If you are not sure about the wiring method, please select unknown, then
the tester will detect automatically. Click the “Save” button after setting completed to
save the information to the database.
5.2 Parameter measurement
Click the “parameter measurement” button to carry out the turn ratio test.
Figure:
Click the “start” button to start the test, and it takes about 3 seconds to complete
the test and then display the testing results. “First” and “Second” is the first and
second voltage of the tested transformer. “Angle” is the difference between the first
and the second voltage angle (clock time). “Ratio” is the measured turn ratio. “Error”
is the error with the standard ratio. “Tap position” is the present tap measured by the
instrument. “Wiring method” is also actual measured wiring method.
When click “save”, the system will prompt which tap records it is to be stored.
Select the correct tap to store the current test results into the database.
