| Abstract: | The mechanism of stray currents occurrence in metro and the monitoring methods are introduced briefly in the paper,the traditional measurements against stray cur- rent are discussed. A new system for monitoring the stray current based on virtual instrument labview is discussed, through which the automatic and continuous monitoring of stray current can be realized.By using this stray current monitoring system,the pipe-ground potential of Shanghai metro Line 2 is tested.The actual results show that the stray ... |
