【Abstract】 Aiming at the present situation of large-scale stray current leakage in DC traction reflux system that is difficult to calculate and measure, a method of calculating the stray current leakage is presented, which provides a basic data support for the evaluation of stray current corrosion risk. Then, with a description of the stray current leakage measurement based on the existing engineering technologies, the calculation method is simulated and analyzed by using MATLAB software.更多还原
