Voltage Dips and Interruptions TEST SETUP From: 61000-4-11 . IEC:2004

7  Test set-up

The  test  shall  be  performed  with  the  EUT  connected  to  the  test  generator  with  the  shortest  power  supply  cable  as  specified  by  the  EUT  manufacturer.  If  no  cable  length  is  specified,  it  shall be the shortest possible length suitable to the application of the EUT.

The test set-ups for the three types of phenomena described in this standard are:

.  voltage dips;

.  short interruptions;

.  voltage  variations  with  gradual  transition  between  the  rated  voltage  and  the  changed  voltage (option).

Examples of test set-ups are given in Annex C.

Figure  C.1a)  shows  a  schematic  for  the  generation  of  voltage  dips,  short  interruptions  and  voltage  variations  with  gradual  transition  between  rated  and  changed  voltage  using  a  generator with internal switching, and Figure C.1b) using a generator and a power amplifier.

Figure  C.2  shows  a  schematic  for  the  generation  of  voltage  dips,  short  interruptions  and  voltage variations using a generator and a power amplifier for three-phase equipment.
