A type of parameter. Voltage is generally expressed in volts (V) or kilovolts (kV) and is used to describe the standardized operating voltage of the overhead wiring. It is recommended to keep volts as the basic unit. An additional parameter is the voltage system of AC (alternating current) or DC (direct current). The most significant voltage systems being used on the European railways are 3000 V (3 kV) DC, 1500 V (1,5 kV) DC, 15 000 V (15 kV) AC, and 25 000 V (25 kV) AC. |
