2 phase supply ststem have 2 wire, one act as a phase and
another act as neutral or we have for safty purpose we go
to earth system so we add anoher one wire for 2
phase.example:red,black,green wire.1.red -act as
phase,2.black act as neutral,3.green act as earth.
for phase to neutral or phase to earth =240volts as per
indian standard.
in 3 phase system has red,blue&yellow here also for safety
need green wire used for earthing.RED TO YELLOW OR YELLOW
TO BLUE OR BLUE TO YELLOW=415V.any one of the two phase we
have 415v,but phase to earth we have 240v.
in the 3 phase system no need separate neutral wire because
phase to phase have 120 deg phase shift,so by the cycle one
phase alternatively act as neutral.
