摘要
4102、4102A、4105接地电阻测试仪由日本共立KYORITSU制造,机器采用数字电路设计,操作时不受接地电压及辅助接地棒的接地电阻影响,并可直接读取接地电阻值等优点,普遍应用在地区及县气象站防雷检测工作中。本文主要介绍地阻仪检测方法和降低接地体电阻的一些方法。
Grounding resistance testing instrument of 4102. 4102A. 4105 manufactures by Japan KYORITSU. The instrument adopts digital circuit design and not influenced by the grounding voltage and grounding resistance of assistance grounding stick while operating. It has characteristics of reading out grounding resistance value directly. It mainly used in the weather station thunder defense testing work. This text mainly introduces the method of testing grounding resistance instrument and reduction grounding resistance.
