接地装置电阻的测量和故障对策

Measure and Countermeasure of Grounding Resistance

介绍接地装置测量的方法,在电气设备交接试验过程中,出现接地电阻值超过设计要求时,针对工程土壤电阻率和地貌特点,提出适用的降阻剂,经实践验证了可行性和实效效果。

This article introduced the measurement method of grounding device in details. When the grounding resistance value observed exceeded the standard design requirements in the process of commissition test for electrical equipment, a proposal of applying appropriate grounding resistance-reducing material was presented and taken into practice according to the actuality of soil resistivity and topography features. At the same time the experiment results showed the proposed method was feasible and effective.
