Composite System of Track Electrification: The composite system of track electrification which comprise are the dc system the single phase ac system the three phase ac system and the composite…
Different Groups of Systems of Electric Traction: As already mentioned, systems of electric traction may be divided into two main groups. (1) The group consisting of vehicles which receive electric…
Different Types of Traction System: The various types of traction system commonly used are described below. 1. Direct Steam Engine Drive. The steam engine drive used to be widely employed…
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…
Methods of Booster Transformer in Electric Traction: In ac traction system return current mainly flows to the substation through track leaving a small portion, which flows through ground because of…
Overhead Equipment in Electric Traction Systems: Simplest type of overhead equipment in electric traction systems consists of a single contact wire supported either by bracket or by overhead span. The…
Operations of Traction Power Controller (TPC): It is provided to have a comprehensive picture of supply conditions and arrangement to operate switchgear with minimum delay so that continuity of electric…
Systems of Track Electrification AC Electrification System: As even in single phase electrification, the substations are necessarily required to keep the voltage drop within permissible limits. The type of substations…
