Voltech AT3600 AT3600 Transformer Tester
Because the programming of each test is done at a high level, it is not strictly necessary for you to know the details of how tests are executed within the tester.
However, for some users this subject may be of interest, therefore a brief explanation has been included here.
When the test program is loaded into the tester, each individual test is assembled into a sequence of operations involving the components in the functional block diagram shown previously. The sequence is different for each test, and in some cases, it depends on which are the preceding and following tests in the program; but in all cases, it is optimized to give the best measurement speed and accuracy.
As an example, the sequence for measuring inductance may be summarized as follows:
For other tests, the sequence may be more complicated.Notes: All the relay switching is completed before the test source is energized; thiswill ensure that there can be no arcing, and prolong the life of the relays.In contrast to some LCR bridges, the AT Series testers trim the test source togive the user programmed test conditions. This will guarantee that the sametest conditions are applied to all transformers that use the same test program.At the end of the test, the source is safely ramped down, so that the relayswitching for any subsequent test will always occur with the source removed.
The test program is simply the list of tests that you wish to apply to your transformer. Clearly individual transformers will each have their own program, but as an example, a typical program for a three winding switch-mode power supply transformer could be as follows:
The Test Program Editor supplied with your tester allows you to create such a program simply and easily without any need for software programming skills. Each test required for the program is selected from a list of ‘available tests’ by clicking with the mouse. The test details (such as the transformer terminals, test conditions, and pass / fail limits) are then entered into a form fill dialogue box.
