Test Procedure
The EUT and its load are placed on a table which is 0.8 meter above a metal ground plane
measured 1m*1m min. And 0.65mm thick min. And projected beyond the EUT by at least 0.1m
on all sides. The power cord shall be used the shortest power cord as specified by the
manufacturer.
For Voltage Dips/ Interruptions test:
The selection of test voltage is based on the rated power range. If the operation range is large
than 20% of lower power range, both end of specified voltage shall be tested. Otherwise, the
typical voltage specification is selected as test voltage.
The EUT is connected to the power mains through a coupling device that directly couples to
the Voltage Dips and Interruption Generator.
The EUT shall be tested for 30% voltage dip of supplied voltage and duration 10ms,
for 60% voltage dip of supplied voltage and duration 100ms with a sequence of three voltage
dips with intervals of 10 seconds, and for 95% voltage interruption of supplied voltage and
duration 5000ms with a sequence of three voltage interruptions with intervals of 10 seconds.
Voltage phase shifting are shall occur at 0
0, 450, 900, 1350, 1800, 2250, 2700, 3150 of the
voltage.

Test Result
The measurement of the Voltage Dips and Interruption was investigated and test result was
shown in section 13. The acceptance criterion was met and the EUT passed the test.
