Traction Power System



In addition to introducing the principles and key elements of the traction power network design process, this traction power system training course is designed to provide a thorough understanding of the fundamentals of traction power supply in railway engineering and systems.

The United Kingdom, Germany, Switzerland, Austria, Central Sweden, Southern Norway, USA, South Africa, Melbourne in Australia, and Riyadh in the Kingdom of Saudi Arabia are among the countries that utilise traction power networks. An overview of the ideas in a basic traction power system will be given in this training course, along with case study examples. This online course is for you if you work in a relevant field and need to comprehend the principles of electrically powered railway systems.
