India. All mainline electrified routes in India use 25 kV AC overhead electrification at 50 Hz. As of March 2017, Indian Railways haul 85% of freight and passenger traffic with electric locomotives and 30,000 km of railway lines have been electrified.
Which motor is used in Indian Railways?
Railway works under the Indian railway which is a state-owned organization of the Ministry of railway. Indian railway traction system uses 1.5 kV DC around Bombay and 25Kv ac is used in rest of the country. The supply for traction system is taken from state utility which is three phase source at 132/220 kV.
Do trains use AC or DC?
Direct current, either directly supplied, or converted from AC onboard a train, is the most commonly used. This is because, according to railsystem.net, “DC consumes less energy compared to an AC unit for operating the same service conditions.
Which city is famous for electric locomotives in India?
Chittaranjan Locomotive Works, Chittaranjan
Chittaranjan Locomotive Works is a state-owned electric locomotive manufacturer based in India. It is located at Chittaranjan in Asansol. It is one of the largest locomotive manufacturers in the world. Chittaranjan Locomotive Works has supplied many types of locomotives.
Which type of motor is used in trains?
Three types of motor are used in locomotives: DC motors. AC motors with variable frequency drives. AC permanent magnet motors.
Which type of motor is used in electric train?
AC induction motors
What is more efficient AC or DC?
1. DC power is significantly more energy efficient than AC power. DC motors and appliances have higher efficiency and power to size characteristics. … The greater efficiency resulting from recent developments in DC converter technology allows improvements in electricity delivery over long distances.
Are all trains Electric?
Electric locomotives may easily be constructed with greater power output than most diesel locomotives. For passenger operation it is possible to provide enough power with diesel engines (see e.g. ‘ICE TD’) but, at higher speeds, this proves costly and impractical. Therefore, almost all high speed trains are electric.
Which fuel is used for train?
Which is the most powerful locomotive in India?
Which is the fastest locomotive in India?
State-owned Chittaranjan Locomotive Works (CLW) has given the Indian Railways its fastest ever engine. The modified WAP 5, which is yet to have a name, is expected to travel at 200 kmph.
Are Indian trains Electric?
Indian Railway uses 25 kV 50 Hz AC traction on all its electrified tracks. Railway electrification in India began with the first electric train, between Chhatrapati Shivaji Terminus and Kurla on the Harbour Line, on 3 February 1925 on the Great Indian Peninsula Railway (GIPR) at 1500 V DC.
Which motor is used in tramway?
Mostly DC series motors are used in this system. For trolley buses and tramways, DC compound motors are used where regenerative braking is required. The various operating voltages of DC traction system include 600V, 750 V, 1500V and 3000V.
Which motor is used in tramways?
This paper compares five different motor types used in variable speed drives: a dc motor with a mechanical commutator and with electromagnetic or permanent magnets excitation, a cage induction motor, asynchronous cascade with a slip‐ring motor and a brushless motor with PM excitation.
Why do trains have two pantographs?
Firstly, two pantographs are fixed as to use the other one when the running panto is damaged. Both of them don’t commission at a time. 2. Usually, Rear panto is preferred over front panto as pulling is more easier than pushing.
