Answer / santosh devath

I think that an electric train work on the 3phase induction motor. And they use capacitor start for running the motor during the starting condition to produce high starting torque which produces high starting speed.....
hit yes if u support the answer given by me or else comment on it if it is wrong so that i can get to know my capability..
Thank you....

Answer / hemant chouhan

in india 25 kv AC 50 Hz supply by OH lines and this power step down by transformer with rectified voltage is 1500V DC for main line service. 750V DC for kolkatta metro train.

Answer / yasodha c

dc series motor only used because it needs some load
(torque) to start the motor..... 25kv supply is used

Answer / p. nath

Application of 3 phase induction motor for drivivg the train
wheel &gear.
Due to conversion of single phase 33Kv over head
transmission line is converted to 3 phase on 500-1500volt
through the cycloconverter & transformer and provide to 3
phase induction motor of the train wheel.

Answer / sridhar

the 25kv is given to avoid transmission loss in the
electricity. actively the motor capacity is by using 110
volts only.

Answer / basant

Electric Trains work on DC Series motors.Electic train works by giving supply to the motor through
the transmission line it may be A.C supply or D.C supply.a
collector is used to collect the supply from the
transmission line and it is given to the A.C motor or D.C
motor.The motor is driven by using gears and belts.

The Overhaed supply is 25kV AC supply. It is step down and
rectified to use at DC supply. The power is used for moving train is about 10,000 volts(10kW).

collector is used to collect the supply from the

motor.The motor is driven by using gears and belts.

D.C series motor, A.C series motor & a.c induction motor
are the motors used to drive the electic train.

25kv a.c supply or 600v,700v D.C supply

Answer / karthick

3 phase induction motor and dc series motor because it need
high starting torque to withstand load.

Answer / bhaskar

How we will get 25KV from Single conductor that is fed
above the train (Over head)

We will get 22KV if we test between 2 phase.

but in traction only one conductor is there, then how we
will get 25KV from single over head line conductor

Answer / mahesh.s

as electric train works an electrical supply,dc series moto
used in electric train dc series motor starting speed is
high,ac supply in 25000V used.

can u guys pls suggest a good material for learning abt switch yard and its components
