I checked again the wires ..all the motors are three phase.
its 5 wire white Neutral , Black , red , blue
(&green grounded)
I measure between white and black 200 volt
between white and red 229 volt
betwwen white and blue 230 volt
between red&Black or Red&Blue or Blue&Black 380 volt.
I have 380 volt from a transformer going to a big panel for controlling machine.
input to this panel 4 wire (3+neutral)
the neutral is floating as the transformer is wye to delta and the panel designed to work with wye.
the problem some breakers on the panel does not work correctly as some...
