电气测量辅助技术探讨

On auxiliary techniques for electric measurement

就精密电气测量系统信号的连接、电源、保护、接地等方面的问题进行了探讨。详细分析了接地线、电场噪声、磁场噪声对测量结果的影响,并提出解决问题的办法和保护措施。

This paper makes a discussion on the signal connection, power supply, protection, grounding, etc. of precision electric measuring system, analyzing at length the effects of earth wire, electric field noise and magnetic field noise on the measuring results. Relevant solution and protective measures are put forth as well.
