Why electric traction is the most efficient of all the systems?

Why electrical traction is the most efficient of all the systems?

An AC traction system has become very popular nowadays, and it is more often used in most of the traction systems due to several advantages, such as quick availability and generation of AC that can be easily stepped up or down, easy controlling of AC motors, less number of substations requirement, and the presence of …

What is the advantage of electric traction?

Advantages of Electric Traction Drives

Due to high starting torque, it is possible to produce high acceleration rates. Electric locomotives require less maintenance compared to other drives. Supply of power to the locomotive is easier through the traction substations.

What are advantages of Kando system?

When operating under the same conditions, the DC train consumes less energy than a Single-phase AC train. The erection cost and maintenance cost of the conductor rail is less than that of a single-phase AC system. No electrical interference with overhead communication lines in the DC traction system.

How can we make traction system efficient?

To make traction systems more energy-efficient, per-vehicle rolling stock power consumption can be significantly reduced by expanding the range of operation over which regeneration can be performed to minimize use of air brakes.

What is difference between electric and non-electric traction system?

The traction system can be classified as non-electric and electric traction systems. A traction system that doesn’t use electrical energy for the movement of vehicle at any stage is referred as non-electric traction system.

What is electric traction explain in brief?

Introduction: By electric traction is meant locomotion in which the driving (or tractive) force is obtained from electric motors. It is used in electric trains, tramcars, trolley buses and diesel-electric vehicles etc.

What are four advantages of traction drives?

This traction drive technology offers, efficiency, smoothness of operation, low noise and vibration, durability and a built in over running clutch.

What are characteristics of good traction system?

(i) It should possess high starting torque so that rapid acceleration can be achieved. (ii) It should be self-contained and compact unit. ADVERTISEMENTS: (iii) The traction equipment should be capable of withstanding temporary overloads.

What is ideal traction system?

Ideal traction system should have capability of developing high tractive effort in order to have rapid acceleration. The speed control of the traction motors should be easy. Vehicles should be able to run on any route, without interruption. Equipment required for traction systems should be minimum with high efficiency.

Why Electric Traction is broadly used in Indian Railways?

In comparison to the principal alternative, the diesel engine, electric railways offer substantially better energy efficiency, lower emissions, and lower operating costs. Electric locomotives are also usually quieter, more powerful, and more responsive and reliable than diesels.

What are the advantages of 25kV system of track electrification over dc system?

The main reason for 25kV voltage used in railway is, that 25 kV AC more economical than 1.5kV DC voltage system. Since 25kV voltage system has higher voltage, the higher voltage reduces the current flow through conductor; this reflects to reduce the conductor size. The cost of the conductor gets less.
