However, from I have seen in different projects, 110 vdc is more popular. I wonder if 110vdc has any technical advantages over 220vdc. which one should I choose for my own plant's dc loads? what are the advantages and disadvantages of any of 110vdc and 220vdc voltage levels to be used to supply dc power to control and protection equipment? thanks hnabaei
