What is Transition Method in Electric Traction? The methods of changing-over the connections from one grouping to another are known as transition method. The change-over from full series (when the…
Plain Rheostatic Starting of Traction Motors (Notching): As already mentioned in this plain rheostatic starting method the voltage across the motor is gradually increased from zero to full (normal) voltage…
Starting and Speed Control of DC Traction Motors: Starting and Speed Control of DC Traction Motors - As already discussed, only series and compound dc motors are suitable for traction…
Negative Booster in Electric Traction: In case of dc traction system, return current flows through the rails, to the substations. So due to this current flow through rails some voltage…
Interference in Telecommunication Circuit in Electric Traction: In all traction systems track is used as a return path for the current. Some part of the current flows through the track…
Systems of Track Electrification DC Electrification System: The substations are necessary for control of electric supply to a considerably long network in systems of track electrification DC electrification system. DC…
Current Collection System in Electric Traction and Types of Current Collection: There are mainly two systems of current collection system for locoÂmotives, tramways or trolley buses viz Conductor rail system…
