Hi folks My test lab's current interpretation of EN55022 is that DC Mains measurements are not required. Sections 5&6 specify measurements done on mains ports, but do not specify whether it applies to AC or DC mains. There is a reference in section nine that specifies conducted disturbance is measured between the phase lead and the reference ground, as well as the neutral lead and the reference ground. Does anyone know whether DC measurements are required for this standard?
