WebThe system which use electrical power for traction system i.e. for railways, trams, trolleys, etc. is called electrical traction. The track electrification refers to the type of source supply system that is used while powering the electric locomotive systems. It can be AC or DC or a composite supply. WebJan 3, 2024 · 29. Trolleys with overhead wires often disconnect momentarily and the high inductance creates an arc of the same current that allows some continuity but with some drop of voltage or power. Whereas AC might cutout in < 10ms. But the real reason is DC traction motors have greater efficient torque needed to start.
