19.3.2 Test Procedure 
 
The EUT was tested for each selected combination of test level and duration with a sequence of 
three  dips/interruptions with intervals of 10 s minimum. Each representative mode of operation was 
tested. 
 
EUT is tested for voltage dips of 100%Ut, 0.5 period, 40%Ut,10 periods and 70%Ut,50 periods, 
for  
100%Ut, both the positive and negative polarity test was conducted. 
 
Abrupt changes in supply voltage was occur at zero crossings of the voltage and at additional 
angles  
considered critical by product committees or individual product specifications preferably selected
