摘　　要：近年来,随着GIS变电站的普及,590系列互感器校验仪越来越多地被使用。在用590系列互感器校验仪进行GIS现场试验中,屡屡出现了试验结果超差的问题。为分析其原因,在辽宁某GIS现场和非GIS现场提出比对试验。通过原理分析,得出试验结果超差的根本原因,最后得出590系列互感器校验仪在长母线管GIS现场慎用的结论。With the popularity of GIS substations, Model 590 transfornler testers are commonly used. However, the test resuh is of- ten out of range when experiment by Model 590 transformer testers in the GIS substation is done. In order to solve the proble,n, com- parison test in GIS substation and non-GIS substation is caaried out. Through the analysis of the principle the root cause is found that Model 590 transformer testers should be used with caution in the long-bus tube substation.
