The document discusses electric traction systems used for railways. It describes how electric traction systems use electric power instead of steam or internal combustion engines to power trains. It discusses the types of electric traction systems including DC traction, AC traction, and multi-system traction. It also describes the components of electric traction systems such as the catenary construction, current collectors, and major locomotive components.

ELECTRIC TRACTION SYSTEM Presented by Dr. A.Franklin Alex Joseph Associate Professor Department of Electrical and Electronics Engineering St. Josephs College of Engineering and Technology 1 Dr.A.Franklin Alex Joseph ELECTRIC TRACTION SYSTEM
CONTENT INTRODUCTION WHY ELECTRIC TRACTION SYSTEM??? TYPES OF ELECTRIC TRACTION SYSTEM TYPE OF TRACK ELECTRIFICATION SINGLE CATENARY CONSTRUCTION COMPOUND CATENARY CONSTRUCTION TYPES OF CURRENT COLLECTOR MAJOR COMPONENTS BLOCK DIAGRAM OF AN A.C LOCOMOTIVE Dr.A.Franklin Alex Joseph ELECTRIC TRACTION SYSTEM 2
INTRODUCTION The process of moving any vehicle is called traction . If the electric energy is use in this process is called electric traction. In the case of non electric traction system, unused of electricity such as steam and IC engine drive. In the case of electric traction system we use electric power for traction system such as railways, tramways etc. Dr.A.Franklin Alex Joseph ELECTRIC TRACTION SYSTEM 3
WHY ELECTRIC TRACTION SYSTEM ??? Cheapness : Low operation cost Cleanliness : Smoke and gas free Maintenance cost : 50% less than other steam engines Starting time and speed : Without loss of time. High starting torque : Uses of D.C & A.C series motor- very high starting torque. Braking : Regenerative breaking is used which feeds back energy. Saving in high grade coal : Saving of non-renewable energy source. Dr.A.Franklin Alex Joseph ELECTRIC TRACTION SYSTEM 4
TYPES OF ELECTRIC TRACTION SYSTEMS There are three types of electrical traction system DC traction AC traction Multi system Dr.A.Franklin Alex Joseph ELECTRIC TRACTION SYSTEM 5
DC TRACTION DC traction units use direct current drawn from conductor rail or an overhead line. The most popular line voltages for overhead wire supply systems 15kV DC and 30kV DC. 600V - 750V DC volt range is used for third rail systems. In other words additional rail is provided for supplying electricity to train and is called conductor rail.

DISADVANTAGES OF DC TRACTION SYSTEM Dr.A.Franklin Alex Joseph ELECTRIC TRACTION SYSTEM 7 Disadvantages :- Expensive substations are required at frequent intervals. The overhead wire or third rail must be relatively large and heavy. Voltage goes on decreasing with increase in length. FIG 2: RAIL DC TRACTION SYSTEM PICTURE COURTESY: https://microcontrollerslab.com/nema-23-sdctraction-pinoutfeatures
AC TRACTION AC Traction units draw alternating current from an overhead line. Typical Voltages Used are:- 25 kV AC, 50 Hz 25 kV AC, 60 Hz Dr.A.Franklin Alex Joseph ELECTRIC TRACTION SYSTEM 8 FIG 3: RAILAC TRACTION SYSTEM PICTURE COURTESY: https://microcontrollerslab.com/nema-23-sdctraction-pinoutfeatures
ADVANTAGES OF AC TRACTION SYSTEM Dr.A.Franklin Alex Joseph ELECTRIC TRACTION SYSTEM 9 Advantages :- Fewer substations are required. Lighter overhead current supply wire can be used. Reduced weight of support structure. Reduced capital cost of electrification. FIG 4: RAILAC TRACTION SYSTEM PICTURE COURTESY: https://microcontrollerslab.com/nema-23-sdctraction-pinoutfeatures
MULTI SYSTEMS Multi-system trains are used to provide continuous journeys along routes that are electrified using more than one system. One way to accomplish this is by changing locomotives at the switching stations. These stations have overhead wires that can be switched from one voltage to another. Another way is to use multi-system locomotives that can operate under several different voltages and current types. Dr.A.Franklin Alex Joseph ELECTRIC TRACTION SYSTEM 10
SYSTEM OF TRACK ELECTRIFICATION Trolley wire or contact wire suspended with minimum of sag so that contact between the trolley wire and current collector can be maintained at higher speeds. This wire is supported by another wire known as catenary. Two different types of Catenary construction can be used Single Catenary Compound Catenary Dr.A.Franklin Alex Joseph ELECTRIC TRACTION SYSTEM 11 FIG 5: TRACK ELECTRIFICATION PICTURE COURTESY: https://makeagif.com/gif/how-stepper-motors-work-electric-motor-Ub5P

Single Catenary Construction Dr.A.Franklin Alex Joseph ELECTRIC TRACTION SYSTEM 16 Provided for speeds up to 120kmph. Span of catenary wire 45-90 m and sag of 1-2m. Relatively Cheaper Less Maintenance Suitable where traffic is denser and operating speeds are low FIG 9: SINGLE CATENARY CONSTRUCTION PICTURE COURTESY: https://makeagif.com/gif/how-stepper-motors-work-electric-motor-Ub5P
Compound Catenary Construction Provided for speeds ranges 190-224kmph. Additional wire called intermediate wire is used to increase current carrying capacity i.e., to have increased traffic density.
