4.1. CTY - CONTINUITY
The continuity test can be placed as the first test in the program to check that the
transformer has been inserted correctly into the test fixture. The test checks that
every winding has a resistance less than a user specified limit, the same limit being
applied to all windings.
The CTY test is an alternative to using an R (Winding Resistance) test on each
winding separately. The CTY test has the advantage of speed of execution; but with
the R test, individual limits can be applied to each winding, to give confidence, for
example, that the correct wire gauge has been used.
On selecting ‘CTY - Continuity’ from the available tests window, the following
dialogue box will be displayed:
To program the test:
1. Enter the maximum resistance limit.
Remember that there is only one limit, and the same value will be applied to all
windings.
If all the windings on your transformer have small resistance values, then choose
the value of 10kΩ, to give the quickest test execution.
If any winding has a resistance greater than 10kΩ, then choose a value bigger
than that expected for the winding with the largest resistance.
2. Select OK. The test specification will then be displayed in the program window.
