3.7. TEST PARAMETERS
Some tests such as the R-Winding Resistance test (as used in the quick start tutorial –
chapter 3) are relatively simple to program because you do not have to set up any test
conditions. This is not the normal case.
The LS - Winding Inductance (Series Circuit) - test is more typical, requiring the test
parameters ‘Signal’ and ‘Frequency’ to be specified
For many tests, including the LS test, you may enter the Test Parameters in two ways:
either by simply keying in the numbers you require, or by using the Measure button.
Clearly, you would type in the test parameters if, for example, they have been
specified by the designer of the transformer. If you are not sure what values to use,
some guidance is given in chapter 7 (Tests & Test Conditions) later in this manual.
If you are using the Measure button to enter limit values, as described in section 3.9
later in this chapter, you may also at the same time have the AT Series Tester enter
the recommended test parameter values.
To do this in the case of the LS test, you simply leave the Signal and Frequency edit
boxes empty at the time you click on the Measure button. If you choose either the
‘mV’ or ‘V’ units button before clicking the Measure button, the test signal
determined by the tester will be entered as a voltage; alternatively if you choose the
‘mA’ units button before clicking the Measure button, the test signal determined by
the tester will be entered as a current.
Note that not all tests allow the test parameters to be chosen by the tester; MAGI -
Magnetizing Current - being a clear example of a test which does not make sense
unless you specify both the test voltage and frequency at which the current should be
measured.
The programming details for each test in section 4 (Programming Tests) of this
chapter specify which tests allow the Measure button to enter the test parameter
values.
