Product Description
HDWR大地网接地电阻测试仪 

Darui Electric recommends:


1.仪器概述

       目前在电力系统中,大型地网的接地电阻的测试目前主要采用工频大电流三极法测量。为了防止电网运行时产生的工频干扰,提高测量结果的准确性,绝缘预防性试验规程规定:工频大电流法的试验电流不得小于30安培。由此,就出现了试验设备笨重,试验过程复杂,试验人员工作强度大,试验时间长等诸多问题。

      HDWR-5A(可选择1A,3A) 型大型地网接地电阻测试仪,可测变电站地网(4Ω)、水火电厂、微波站(10Ω)、避雷针(10Ω)多用机型,采用了新型变频交流电源,并采用了微机处理控制和信号处理等措施,很好的解决了测试过程中的抗干扰问题,简化了试验操作过程,提高了测试结果的精度和准确性,大大降低了试验人员的劳动强度和试验成本。
