Investigating ground currents leaking from rails in DC and AC traction

Popis výsledku v původním jazyce

In electric traction, such as railways or trams, rails are used as a return conductor for electric current. As the insulation of rails from the ground is not perfect, a certain amount of current will always be leaking into the ground, forming so-called stray currents. If stray currents get into contact with metal objects buried in the ground, such as buried piping, they contribute to their unwanted and dangerous corrosion. This paper deals with measurements of currents flowing through rails, which havebeen performed by our team in recent years. The aim was to determine the percentage of current flowing through the ground for both DC and AC traction. Designing a computer based system for measuring current flowing through rails required the solution ofcertain accuracy related problems, especially on-site calibration. As our measurements were performed simultaneously at several locations, it was also necessary to ensure exact time synchronization with the use of GPS.
