Abstract：The application of the Kelvin bridge method and the DC four probe resistivity testing technology in alumi-numfoilcapacitors aremainlydiscussed.The testaccuracyoftheKelvinbridgemethodandtheDCfourprobemethod arecompared，andtheinfluenceofdifferent testconditionsonthetwo methodsiscompared.TheKelvinbridgemethod hascertainrequirementsonthespecificationsoftestsamples，andthetestresultsaremoreaccurateandsuitableforarbi-trationtest.TheDCfourprobemethodhasloweraccuracyandissuitablefortherough test，butthedemandis nothigh onthetestsamplespecifications，andthetestismoreconvenient.
