traction means to move forward a vechile ... and so a
system when move forward by means by elctric is known is
eletric traction.....in electric traction mainly we have to
run a moter by means of electric ...and for running a motor
we need some power ckt and control ckt ....
in eletric system the most important thing is his breaking
system ...becoz when a driver call for a brake then he
suddenly disconnected it from overhead lines but due to
interia motor will take some more time to stop
for this we use some new braking system /....
1.regenerative breaking
2.rehostatic system
in all these system the main concept is that the power ckt
has changed to braking system during breaking ....
