钳形接地电阻测试仪在油库加油站使用中的局限性

摘要

The measuring principleand method of clamp grounded resistor tester were introduced briefly. Combining the practice of grounding types of lightning protection and anti-electrostatic in oil depot and gas station, the limitation of applying clamp grounded resistor tester in oil depot and gas station was analyzed.%简要介绍了钳形接地电阻测试仪的测量原理和测量方法，结合油库加油站的防雷、防静电接地形式的实际，分析并指出了在油库加油站使用中的局限性，认为该测试仪仅适用于单点独立接地系统的检测，在当前大都对油罐和其他设备建成地网连接的油库加油站使用，可能会造成一定的安全隐患，但可用于对接地网的安装质量与接触情况的检测和其他场合。
