摘　　要：首先介绍了杂散电流的基本概念、特点及分类,接着分析了目前国内外测试杂散电流的两种主要检测技术的工作原理,并且总结了杂散电流测试仪在实际工程中的应用,介绍了杂散电流测试仪的构成和功能特点,分析比较了国内外杂散电流测试仪,最后介绍了各种防护措施的工作原理,同时总结比较了各种措施的优缺点。通过对杂散电流的研究分析,可以为找出主要问题,探索解决的方案,并为降低杂散电流的影响提供了有力参考。The feature and sorts of stray current are introduced in the first place. Then, two principal methods for stray current testing at home and overseas are analyzed. On the one hand, the application of a stray current tester in real projects is summarized. On the other hand, the constitutions and functions of the current tester are introduced, and the different stray current testers are compared. In the end, all kinds of protective principles are proposed for stray current corrosion, as well as the virtues and flaws of all kinds of protective measures are compared. According to the research and analysis of stray current, we can find out the main issues and solutions. Furthermore, these schemes are references for decreasing the impact of stray current.
