    Hello
    Why there is different in voltage of 3 phase 410V 423V 419V Red green blue

    Insufficient information. Please elaborate.
    Are these measured voltages or is this a theoretical question?
    Are these phase-to-phase voltages or phase-to-neutral?
    Are the colors in any way important?

    If measuring to neutral and there are single phase loads between the phases and neutral then varying 1ph loads will cause unbalance.

    No wonder this Op has the stutters......"RTYTYBTRYRTY"

    If those 400v levels are phase to neutral, what is the phase to phase level (1000V..??)

    As requested, we need more information.

    Is this generator or mains supply?

    Voltage will be phase to phase, not phase to neutral. Phase to neutral will be about 240v for your system.

    Put the same load on each phase.

    Outside your house and mine as well but anyone's guess what the Op is playing with.

    @RTYTYBTRYRTY : You're firing questions at us without showing that you consider the responses given, less an understanding of 3 phase systems.
    Please get informed about the basic operation of three phase systems (here's another link) and if open issues remain, come back with more clear questions.
    For the time being I'll close this thread.
