Answer Posted / abhishek uppal
1H.P= 0.746 watts i.e power
so in 3 phase ,power =root3 *v*flc(Il)*cos phi
power =.746 watts
v=415v, and cos phi=0.8...so substituting above values
0.746=1.732*flc*415*0.8
so 7460/1.732*415*0.8= 1.31 A
So flc=1.31A...so accordingly,
find for 30 kw.

Can u explain : what is supply for train (whether a,c or d.c ).I know that supply is 25000v a.c .But there is rumour that supply is D.C. And also explain how lights and fans inside the trains are working ,and what type of motors are used in trains whether D.C motors or induction motors .If d.c motor, how it gets supply.If traction motors are used then what are traction motors and its functions and how it differs from other motors and also explain about locomotive . y d.c series motor in train.train wheels r driven by D.C shunt motor ,at what voltage,and at what speed. please reply..............
