请参考IEC61000-4-5 2014 新规定。
新标准要求在CDN输出端计量
Coupling method CWG output voltage a,b,c Voc at CDN EUT output ± 10 % Voltagefront time Tf Tf = 1,67 × Tr ± 30 % Voltageduration Td Td = Tw ± 30 % Isc at CDN EUT output ± 20 % Current front time Tf Tf = 1,25 × Tr ± 30 % Current duration Td Td=1,18 × Tw ± 30 %
