一、仪器简介
HRJDT型电力设备接地引下线导通电阻测量仪克服了同类仪器存在的测试方法繁琐、工作强度高、精确度低等一系列缺陷。该仪器采用直流恒流电源供电,采用大电流、四线法的测量原理有效地排除了测试线电阻对测试结果的影响,并可直接得到测量回路毫欧级电阻数据,并且仪器选用高精度测量电路,具有抗干扰能力强,操作方便,测试数据迅速、准确等优点。
传统的导通测量仪器一般情况下,需要俩到三人来完成测试的全过程。而本公司生产的HRJDT型电力设备接地引下线导通电阻测量仪配有公司自主研发生产的HRJDT型手持式探针,这样不仅大大缩减测试人员的数量(一人就可以完成整个测试的全过程),而且测试数据准确、直观、稳定。
