5.MAINS TERMINAL CONTINUOUS DISTURBANCE VOLTAGE  
 
5.1 Test result 
 
           Pass              Fail             Not applicable 
 
5.2 Operating environment 
 
Temperature:                       22 °C 
Relative Humidity:              48  % 
 
5.3 Test set-up and test procedure 
 

 
 
 
 
The mains terminal disturbance voltage was measured with the equipment under test(EUT) in a 
screened room. 
The EUT was placed on a 0.4m high  non-metallic table above a 2m by 2m in size ground  reference 
plane(GRP),and keeps a distance of at least 0.8m from any of the other metallic surface. 
The EUT was connected to an artificial mains network and at a distance of 0.8m from it. The mains 
lead excess 0.8m was bundled to 0.3m or 0.4m parallel to the lead.  
 
Amplitude measurements were performed with a quasi-peak detector and, if required, with an average 
detector. 
 
5.4 Measurement uncertainty 
 
Mains terminal disturbance voltage, quasi-peak detection:                     + 2,0 dB 
Mains terminal disturbance voltage, average detection:                          + 2,0 dB 
 
The measurement uncertainty describes the overall uncertainty of the given measured value during the 
operation of the EUT in the above mentioned way. 
 
Measurement uncertainty is calculated in accordance with WECC 19-1990. 
The measurement uncertainty is given with a confidence of 95%
