Arc Furnace - Definition, Types, Advantages and Application: When a high voltage is applied across an air gap, the air in the gap gets ionised under the influence of electrostatic…
Resistance Heating - Types, Advantages and Applications: Resistance heating is based upon the I2R effect. This method of heating has wide applicaÂtions such as heat treatment of metals (annealing, hardenÂing…
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…
Thyristorised Control of DC Electric Traction Motor: The modern trend is towards the use of dc motors (both separately excited and dc series motors) equipped with thyristor chopper control. The…
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…
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…
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…
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…
