Kostin The influence of the short circuit condition in the contact system on electromagnetic processes in electric train of direct current. The influence of the short circuit condition in the contact system on electromagnetic processes in electric train of direct current was estimated by the method of mathematical modeling. It has been established that in this condition the current of an electric locomotive canges for traction current info generative (recupera-tive) one. Key words mathematical modeling, short circuit condition, contact system, electromagnetic processes, electric train of direct current.
