Field / Control Description
Either one or both sequences can be selected for execution.
Output Select The output selection is shown to the left. If a 3 phase AC/DC power
source model is used, this field allows selection of output channel A,
B, C or all three channels (outputs). The same test sequence is
applied to all selected outputs. For single phase power systems, this
field defaults to channel A.
Start Starts the IEC 61000-4-29 test using the parameters set by the user.
Test progress is shown at the bottom of the window.
Abort Aborts test in progress.
13.2 Setting nominal values
The IEC 61000-4-29 test requires setting of the rated nominal DC voltage of the EUT. The
nominal values must be entered in the Test Setup Nom. Vdc data field before starting a test.
When the IEC 61000-4 test windows is first opened, the present DC voltage setting is
automatically loaded as the nominal Vdc value. This value is overridden by selecting each data
entry field and typing in a new value or by loading a test file from the File, Open menu. Thus, test
data files also contain the nominal Vdc voltage to be used.
13.3 Test sequence
The test sequence implemented by this test consists of a series of DC voltage dips (to less than
DC nominal) or interruptions (dip to zero volt). It is also possible to select voltage variations which
cause the DC voltage to change at a programmed rate to a specified level and then return at the
same or a different rate to the nominal DC level. The objective of this test is to evaluate a product
for immunity from such dips, interruptions and variations.
These dips and variations can be applied at different levels and durations for different product
categories. The user must determine the product class and select the appropriate test file. The
selected levels and durations are visible on screen and can be edited and saved to a new setup
file if needed. This allows a library of test files for specific product categories to be created. The
.429 file loaded determines the test levels and DC nominal values used. It can also contain
information on the EUT and operator. The maximum number of steps that can be defined is 100
for both Dips/Interruptions and Variations.
These parameters can be entered on screen by the operator or loaded from disk. To load a new
test or test class, select the File, Open menu. The default location for IEC test files is:
C:\Program Files\California Instruments\Cigui32\IEC_Test.
Or
C:\Program Files\California Instruments\CiguiSII\IEC_Test.
The following duplicate sets of IEC 61000-4-29 test files are distributed with the CIGui32 or
CIGuiSII program:
