  Re: sir, my question is that if we start any three phase induction motor with star connection.will be current taken ? please send a formula.
Answer
# 1
pls find the formula

  P=eta root3VI cosfie
  I=p/eta root3V cosfie
where p= power of motor
      eta= efficiency
       V= voltage
        I=current
     cosfie= power factor

Answer
# 2
Pls find the formula

  P=Root3*V*I*P.f
  
  I=P/Root3*V*P.f.

  "P" is Capacity of the 3 Phase IM.

Answer
# 3
p=root3 vi cospie


   p=power in motor

   root3= three phase

   v=voltage
   i=current    cospie= pover factor
