摘要
测量标准雷电波所用数字记录仪非线性评价方法的研究,对我国计量部门建立相应的标准装置具有重要意义。本文介绍了IEC 61083-1关于冲击测量用数字记录仪幅值非线性评定方法的原理,从计量校准的角度出发,探讨了静态非线性和动态非线性的评价指标和实现方法,列出并比较了两种典型数字记录仪的非线性评定结果。
It s significant to evaluate the non-linearity of digital recorders for standard lightning impulse measurement,based on which the standard device can be set up.In this paper,evaluation procedures of non-linearity of digital recorders recommended in standard IEC 61083-1 are introduced.For accurate measurement,the evaluation specifications and methods of both static and dynamic non-linearity are discussed and applied to two typical digital recorders.
