摘要
接地装置是防雷系统的重要部分而接地电阻测试是防雷检测工作的重要环节。检测人员不严谨的操作可能成倍放大理论误差。延长线盘可能带来难以排除的操作误差。本文分析了接地电阻测量的误差来源,提出降低误差的方法,并引入导通性能测试优化试验流程。实践证明,该方案可有效提高测量的精确度和工作效率。
The grounding device is an important part of lightning protection system and grounding resistance test is an important part of the lightning protection test. Not rigorous operation of testing personnel may multiply the theoretical error. Extension of cord disk may bring operation error that is difficult to remove. Grounding resistance measurement error sources are analyzed in this paper, and methods to reduce error are put forward, and the conduction performance is introduced to optimize the testing process. Practice has proved that this scheme can effectively improve the measurement precision and work efficiency.
