Recent trends in green energy development make that photovoltaics and electric vehicles are applied on an increasing scale. In both photovoltaic and electric vehicle charging installations, a significant value of DC component of the earth fault current may appear, which is a challenge, in particular, for commonly used residual current devices (RCDs). This paper presents results of the laboratory test on the operation of F-type RCDs – a type that is just beginning to appear in low-voltage installations. It has been checked how the tripping threshold of RCDs changes, if a smooth DC component is superimposed on the sinusoidal alternating current. It has been found that the F-type RCDs can operate very well even in the presence of a very high value of DC component.
