Answer Posted / a.lingadurai
The winding resistace varies according to the connection
of star / delta. When star connected motor, measured
resistance shows the value of two resitance in series.
When delta connected motor,measured resistance shows the
value of two resistance series and another resistace
parallel with them. So we can identify by the value of
resitance.
Also the phase current of motor is equal to line current
for star connected motor. For delta connected motor the
line current is 1.732 times of phase current.
