DC & AC Rail Electrification - Optimised railway electrification solutions

DC & AC Rail Electrification - Optimised railway electrification solutions

DC Electrification – Globally almost half of all electric railways use direct current traction. In mass transit systems, maximum nominal voltages up to 1500V are used because of the potential danger of higher voltages. The most common voltages are 750V and 1500VThe distance between substations varies from 1km to 6km. In the design and operation of direct current railways, special attention has to be paid to the problems of traction current return to minimise the hazard of stray current corrosion. The presentation will tackle these matters.

AC Electrification - Introduction to converter solutions for improved railway grid feeding concepts, including the pros and cons between the various technologies and reference to local and global project sites.
