There is no such thing as a DC 3 phase system. Polyphase systems are relevant only to alternating current systems and there is no phase applicable on a direct current system. Like the other answer pointed out, if you mistook the 3 wire DC system for 3 phase DC, then you assumption is incorrect. No such thing as a polyphase DC system.
