9.4 Option –411: IEC 61000-4-11 Voltage Dips and Interruptions
9.4.1 General
The IEC 61000-4-11 option can perform IEC 61000-4 section 11 voltage dips,
short interruptions, and voltage variations immunity tests. On three phase MX
Series AC sources, the user can select one, two or all three phases to be active
during the IEC 61000-4-11 tests in this configuration.
9.4.2 Standard Revisions and EUT Classes
The–411 option supports both the first (1994-06) and the second edition (2004-
03) of the IEC 61000-4-11 test standard as of firmware revision 0.31. Older
firmware revisions only support the first edition. Contact technical support at
techsupport.ppd@ametek.com
for upgrade information. If Edition 2.0 is
supported, the standard revision can be selected when using the Virtual Panels
Windows program. From the front panel, there is no need to select the revision,
but data values can be set that support either version of the standard.
Generic tests files are distributed with the Virtual Panels program for both
editions of the test standard. Files applicable to Edition 2.0 have ED20 in their
file name. Do not mix these files, as the data setup will not be correct if you do.
To load a test file, select the Mode (Dips or Vars) and test standard revision
first, then use the File, Open menu to load the test parameters. Test parameters
can be a function of the EUT class. The different files provided with the program
cover the various EUT classes. The relevant EUT class 1, 2, 3 or X is listed in the
file names.
When using front panel operation, the user must set levels for each individual
test step in SINGLE mode.
9.4.3 Initial Setup
The user must set the operating frequency and voltage and close the output
relay prior to the start of test. It is possible to change the normal voltage (Ut)
from the IEC1000-4-11 menus before running each test.
9.4.4 Phase Selection
On three phase power source models, phase selection for individually executed
dips or the preset RUN ALL selection can be made using the PHASE key on the
front panel. The phase or phases selected will be displayed in the upper right-
hand corner of the LCD as either A, B, C, AB, AC, BC, or ABD.
With the introduction of Edition 2.0, three phase voltage dips testing has been
redefined for both Wye and Delta loads.
