Traction Power

• BACKGROUND
• This is a new stream in the new Higher Diploma in
  Electrical Engineering
• This stream aims to fulfil the REW Grade B
  academic requirement and
• This stream covers the works in traction and
  railway system, locomotive and electrified
  trains, rolling stock and depot, and vertical
  transportation system.

Traction Power

• Potential Empolyers
• After meeting with KCRC, MTRC and LE Co., they
  are in general supporting this stream, especially
  the term time project and placement.
• Potential employers not only include MTRC and
  KCRC, but also their consultants and contractors.

5
Objectives of the StreamTraction Power

• Aim at teaching students the theories of advanced
  electric drives used in HK,
• Knowledge of power system specified to MTR
  (1500Vdc) and KCR (25kVac), and to their stations
  (ELV in BS area)
• Concept of Rolling Stock Maintenance and
  signaling/protection in local traction system.
