When providing the maximum 500 kW HEP load, maximum traction power is reduced to 2, 930 hp since HEP generation diverts some power from the prime mover.
32.
However, there are some lines of this type for lower voltages, for example, towers used by both railway traction power circuits and the general three-phase AC grid.
33.
The power supply was connected to the traction power network by means of two new spur lines running via three new substations at Roth, Ilmenau and Eischleben.
34.
However, much larger universal motors were used for electric locomotives, fed by special low-frequency traction power networks to avoid problems with commutation under heavy and varying loads.
35.
From Washington, D . C ., to Sunnyside Yard ( just east of New York Penn Station ), 60Hz traction power system supplies 25 kV at 60 Hz.
36.
On Line 2, Siemens Transportation Systems equipped the line with an overhead contact line ( cantilever material : galvanized steel ) and 7 DC traction power supply substations.
37.
In some countries where electric locomotives or electric multiple units run on low frequency AC power, there are separate single phase traction power networks operated by the railways.
38.
The principal hazards include collisions between a rail vehicle and a track worker, electrocution from traction power sources ( third rail, fourth rail, OHLE ) and trips and falls.
39.
The climb to the summit at Beattock continued to be a daunting obstacle until electrification on 22 April 1974, since when the available traction power has diminished the problem.
40.
The traction power system of this car has its own main transformer, supplied by high voltage from the first traction head, rather than the second that is next to it.
