arranged and connected to satisfy its functional requirement.
All relevant cables were provided with the appropriate coupling and decoupling
devices at a distance between 0.1m and 0.3m from the projected geometry of the EUT on an
insulating support of 0.03m height above the ground reference plane.
The frequency from 0.15MHz to 230MHz was checked.

Notes:
1.“*” for 0.5 period, the test shall be made in positive and negative polarity, i.e.
starting at 0
° and 180°, respectively
2. “**” means “x” is an open duration. This duration can be given in the product
specification.. Utilities in Europe have measured dips and short interruptions of
duration between ½ a period and 3000 periods, but duration less than 50 periods
are most common.
3. if the EUT is tested for voltage dips of 100%, it is generally unnecessary to test for
other levels for the same durations. However, for some cases(safeguard systems or
electro-mechanical devices) it is not true. The product specification or product
committee shall give an indication of the applicability of this note.

19.3 Test Setup and Test Procedure
19.3.1 Test setup
The EUT was placed on an insulating support of 0.8m height, standing on a ground reference
plane, and arranged and connected to satisfy its functional requirement
The test was performed with the EUT connected to the test generator with the shortest power
supply cable as specified by the EUT manufacturer.
