Abstract:The national standard GB / T 16895.23 - 2020 Low‑voltage Electrical Installations — Part 6:Verification equivalent to IEC 60364 - 6:2016 is introduced. Combined with the standard content,the problems such as“three elements of verification”,“1m conductor principle”,fault loop impedance test,RCD effectiveness test and earth electrode resistance test are discussed,and the fuzzy understanding of related problems is clarified.
Key words:low‑voltage electrical installations;fault loop impedance;RCD effectiveness;earth resistance;conductor continuity;verification; inspection;testing
摘 要:对IEC 60364 - 6:2016《Low‑voltage Electrical Installations — Part 6:Verification》等同转化的国标GB / T 16895.23 - 2020《低压电气装置 第6部分:检验》进行介绍。结合标准内容对“检验三要素”、“1m导体原则”、故障回路阻抗测试、RCD有效性测试、接地极电阻测试等问题进行讨论,并就相关问题的模糊认识进行澄清。
