What is a traction??

The act of drawing or pulling.
When the above act is done by electricity, then it is nothing but electric traction.
Electric traction also means a locomotive in which the propulsion (tractive or driving) is obtained by the use of electricity.

Electrification System:

Electrification systems are classified by three main parameters:

Contact system


a)Direct current: The DC system is quite simple but it requires thick cables and short distances between feeder stations because high currents are required.

b)Alternating current: These are overhead electrification systems. Alternating current can be transformed to lower voltages inside the locomotive.

Contact System

a)Over head system: The supply of electricity is through an overhead system of suspended cables known as the catenaries.

b)Third rail system: A third rail is a method of providing electricity to power a railway through a continuous rigid conductor alongside the railway track or between the rails.

Railway electric traction describes the various types of locomotive and multiple units that are used on electrification systems around the world.

Electric traction :
Here power is applied to the vehicle from an overhead wire suspended above the track.

Electric traction systems may be broadly categorized as those operating on :

1. Alternating current supply

2. Direct current supply.

In general following electric traction systems exist :

(A) AC 3 phase 3.7 kV system

(B) AC single phase 15/16 kV -161/25 Hz

© AC single phase 20/25 kV - 50/60 Hz

(D) DC 600 V

(E) DC 1200 V

(F) DC 1.5 kV

(G) DC 3 kV.

Electric Traction > Advantages :
Electrical transmission, which is usually applied to high power units, has following advantages:

1. It has smooth starting without shocks.

2. Full driving torque is available from standstill.

3. Engine can be run at its most suitable speed range. This given higher efficiency range.

4. Characteristics of traction motor and generator are so chosen that the speed of the traction unit automatically adjusts according to the load and gradient so as to maintain constant output and not to overload the diesel engine.

5. Electrical transmission docs not only work as torque converter but also works as reversion gear.
