Answer / er. nitin sonkar

when a motor is connected in star the the line current is
equal to phase current but line voltage is equal to root 3
times the phase voltage.

and when motor is connected in delta line current is equal
to phase current divided by root 3 and line voltage is equal
to phase voltage

Answer / gangadharan

The different between star and delta connection is speed
and current.

in star connected motor current is less than delta
connected motor and speed also less star connected motor
than delta connected motor.

Answer / kosh pradeep chauhan

In case of delta have incoming of voltage is same like Vp = VL and incoming of current is different like Ip =IL /√3 in case of star have incoming of voltage is different like Vp =VL/√3 and incoming of current is same means Ip = IL .

Answer / kosh pradeep chauhan

In case star have same current ip = iL and voltage is different Vp = VL/√3 in case of delta it is work opposite of star .its incoming of current is different Ip = iL /√3 and voltage is same Vp = vL.

Answer / alternate_reality

In delta connection the motor winding is connectoed in
delta by changing the strips or links provided with the
motor, similarly in star connection the motor winding is
connected in Star by changing the links provided with the
motor....
