Direct current (DC) traction units use current drawn from a third rail, fourth rail, ground-level power supply or an overhead line. AC voltage is converted into DC voltage by using a rectifier. Alternating current (AC) Traction units involve an Inverter and produce variable traction output based on the frequency of the AC current. They are equipped in most modern rolling stock for lower maintenance cost and easier scalability relative to DC units. WebThe voltages used for traction current lines are 110 kV in Germany and Austria and 66 kV or 132 kV in Switzerland. Traction current lines are operated symmetrically against earth. In the case of 110 kV lines, for example, each conductor has a voltage of 55 kV against earth.
