基于电测技术中的电磁干扰分析及抑制措施

Analysis of electromagnetic interference in electrical measurement and its controlling measures

在电气测量中,实际的测量结果与真值总是存在一定的误差。这些误差除存在不可抗拒原因之外,还有来自测量系统内外的一些干扰因素有关。对这些电磁干扰因素可加以分析,并采取一定的方法加以抑制,以减小测量误差。

in electrical measurement, there is difference between the real measurement result and true value. Beside force majeure, some interference within or outside the measurement system may cause error. This paper analyses electromagnetic interference in electrical measurement and puts forward some controlling measures.
