Mirosław Romański talks about a characteristic phenomenon accompanying electric railway traction network, i.e. stray currents. These are currents flowing from the traction network through the ground. After the rail vehicle has taken current from the substation through the upper traction network, the circuit is closed and the current returns to the substation through the tracks and return cables. The current flowing through the ground branches off, and part of it returns to the substation through the ground through unforeseen paths. The flow of stray currents is facilitated by elements of the terrain infrastructure such as various types of cables, pipes, etc. While stray currents do not cause damage when they enter metal devices located underground, they cause corrosion when they leave them. In order to limit stray currents, insulation of rails from the ground and metals with the lowest possible resistance is used, and cathodic protection of the facilities is also applied. --------------------------------------------- ✅ Production, development and editing: MIROSŁAW ROMAŃSKI ------------------------------------------------------------ ✅ If you are interested in receiving notifications about new films, please subscribe to the channel ???? ???? / mirmur2 ago you will receive regular notifications about materials on this channel -------------------------------------------- ✅ IF YOU WANT TO SUGGEST A FILM TOPIC OR HAVE ANOTHER QUESTION, YOU CAN WRITE: ????
