汉川电厂地网接地电阻测量与改造方案探讨

Ground Resistance Measurement and Research of Reconstruction Scheme for Grounding Grid in Hanchuan Power Plant

介绍了采用变频技术测量汉川电厂地网接地电阻的方法和结果，并对汉川电厂地网的改造方案做了初步探讨，对大型地网接地电阻的测量和地网改造有一定的参考价值。

By using frequency changing technology in ground resistance measurement for grounding grid in Hanchuan Power Plant,the measurement result of ground resistance is obtained. The method and result are presented. The reconstruction scheme for grounding grid is studied and it will be refer- ence for other grids.
