摘要
提出了一种仅用一台通用高阻标准器和台式数字多用表来完成兆欧表中值电压和开路电压的计量方法。通过调节高阻标准器的阻值以及改变和数字多用表的连接方式,组合出所需的测量电路。实验结果表明,该方法实用性强,操作方便,灵活度高,减低了成本,提高了设备的使用率。
The article puts forward a new method to measure the median voltage and open circuit voltage of meggers,by only using a general-purpose high resistance standard and a desktop digital multimeter. We got the right circuit through adjusting the high resistance standard and changing the connection with the digital multimeter. The experimental results show that this method is practical,easy to operate,full of high flexibility,reduces the cost and improves the efficiency of the equipment.
