How to identify 3 phases of 3 phase supply irrespective of
there color????
Answer / dharmans
step-1-: the three phases of alternator connect to the
primary of which is our auxiliary transformer then the
output is connect to the LT bus which is have 440v rated.
then connect to a 3phase motor through a breaker or rated MCB.
step-2-: now observe the rotating direction from the drive
end side of the motor. if the motor rotating to
anti-clockwise direction the connection of cable color code
is R,Y and B. if the motor rotating to clockwise direction
of the cable color code is Y,B and R.
