Dynamic Stray Current Measuring Methods in Urban Areas

In areas where urban tracks are used as public transportation, dynamic stray currents cause high maintenance costs for the and metal structures near tracks. S tray caused by rail vehicles depend on many factors (traffic density, vehicle speed, acceleration deceleration, soil track moisture), so it is very difficult to get a clear picture of harmfulness current based results single field measurement. However, there several measurement methods that can be determine presence predict appropriate actions. Some these described in this article, namely use mapper, potential current, at collection system, non-destructive sensors. construction, measuring electrical between ground one most common detecting damaging influence current.
