KEMA试验室与国内试验室互感器试验方法的差别分析

Analysis on Test Method of Instrument Transformer Between KEMA and National Laboratories

文章介绍了KEMA与国内试验室在CVT铁磁谐振及CT短时电流项目上的试验方法,通过对比说明及计算较为深入地分析了两者的差异,同时,还列举了一些国内外试验室在细节上的不同之处。最后给国内的互感器厂家及国内试验室提出了一些建议。

In this paper, the test method in ferro- resonance of CVT and short time current of CT between the KEMA and domestic laboratory are introduced. The differences between them are analyzed deeply through comparison and calculation and, at the same time, the difference details between some domestic and foreign laboratories are listed. Finally, some suggestions are proposed for the Chinese instrument transformer manufacturers and test laboratories.
