Abstract

The IEC 60060-1 (2010) and IEEE 4 (2013) Standards establish the k-factor function to determine the test voltage value of lightning impulses (LI) with superimposed oscillations. The test voltage function is included in these Standards to enable a more accurate and consistent determination of the test voltage and the time parameters, of LI with superimposed oscillations of any frequency content. The experimental k-factor function was determined by five research European institutes, but no dielectric fundaments were given to justify the k-factor function. This paper presents a specific study that was performed to validate the k-factor approach by checking its compatibility with the disruptive physic phenomenon. The same testing data used for determining the k-factor function for the air dielectric medium were used to determine the disruptive effect area model proposed by Kind in 1958. The results obtained ratify the compatibility between the k-factor function and the disruptive effect area model. The results presented in this paper are considered a valuable information for future research related to the test voltage k-factor function to improve the current International Standards.

IEC 60060-1和IEEE 4标准中确定带超冲雷电脉冲试验电压的k因子函数的介电原理

IEC 60060-1（2010）和IEEE 4（2013）标准建立了k因子函数来确定叠加振荡雷击脉冲（LI）的测试电压值。测试电压功能包含在本标准中，以便能够更准确和一致地确定具有任何频率内容的叠加振荡的LI的测试电压和时间参数。实验k因子函数由欧洲五家研究机构确定，但没有给出介电原理来证明k因子函数的合理性。本文提出了一项具体的研究，通过检查其与破坏性物理现象的兼容性来验证k因子方法。用于确定空气介质k因子函数的测试数据与1958年Kind提出的破坏效应面积模型相同。所得结果证实了k因子函数与破坏效应区模型的相容性。本文的研究结果可为今后有关测试电压k因子函数的研究提供有价值的信息，以完善现行的国际标准。
