Group,
The EN61000-3-2 standard has always listed absolute current values for harmonics produced in a 230-240VAC 16A line. Tests of wide-range input units are performed in the 230-240VAC condition. Obviously, equipment drawing much less than 16A @ 240VAC, could draw the same harmonic currents as a 16A device and still meet the standard. Is this valid compliance? Because phase angle is not considered, a unit could also develop harmonics or fundamental phase angles (even inversion), which could actually cancel distortion produced generally in other equipment. Is this effect handled in any way?
