Test Implementation and Test Sequence
For each test step, the specified voltage and phase angles will be applied for the time specified. At the
onset of each voltage/phase step, the source voltage is captured by the power source's data acquisition
system. Once the specified time has elapsed, the voltage and phase angles are set back to their nominal
values and the captured waveform data is transferred and displayed. This data will be visible until the next
step when it is updated. Each step (number) will be applied for a different phase rotation in the sequences
shown below. This means the operator does not have to reconnect the EUT three times using a different
phase connected at each test number.
The phase rotations used are as follows:
Sequence
First
Ua to L1
Ub to L2
Uc to L3
Second
Ua to L2
Ub to L3
Uc to L1
Third
Ua to L3
Ub to L1
Uc to L2
The test numbers executed are determined by the test selection in the main setup screen. Any combination
of test number 1, 2 and 3 may be selected by placing a check mark in the appropriate box.
11.10 Test Reports
The EN 61000-4-27 test module produces a test report when the Print Report button is clicked or the File,
Print menu is selected. Test reports include all selected test parameters and options. Note that IEC reports
can be generated using one of three alternative methods. See the options menu for details. The IEC 61000-
4-27 report generator supports direct printer output or output to a MS Word document. The waveform
display that is included in the report is the one that was captured at the last unbalance applied to
the EUT.
