隨著現(xiàn)代化技術(shù)的不斷更新和拓展，對(duì)電力系統(tǒng)及高電壓設(shè)備的可靠性也提出更高的要求，電氣設(shè)備出現(xiàn)事故或是損壞，通常與絕緣的缺陷密切相關(guān)。電氣設(shè)備的大容量化、高電壓化、結(jié)構(gòu)多樣化及密封化，對(duì)電氣設(shè)備應(yīng)提出更新的、更高的要求。大容量設(shè)備的使用不斷增加，用普通的兆歐表無(wú)法檢測(cè)其絕緣性能。電力試驗(yàn)規(guī)程對(duì)眾多的電力設(shè)備如：電纜、電機(jī)、發(fā)電機(jī)、變壓器、互感器、高壓開(kāi)關(guān)、避雷器等要求做一系列的絕緣性能試驗(yàn)，首先是要做絕緣電阻測(cè)試。在測(cè)試大容量電力設(shè)備的絕緣電阻時(shí)，絕緣電阻值和加壓的時(shí)間有關(guān)，加壓時(shí)間越長(zhǎng)，絕緣阻值越高，這種現(xiàn)象叫絕緣的吸收現(xiàn)象。要了解被試品的絕緣性能必須首先對(duì)其做吸收比和極化指數(shù)試驗(yàn)，為下一步的泄漏、介質(zhì)損耗、局部放電等，絕緣性能試驗(yàn)提供安全保障。我公司依照電力標(biāo)準(zhǔn)化規(guī)程特推出大容量、高抗干擾、性能穩(wěn)定的絕緣電阻測(cè)試儀，對(duì)電力設(shè)備進(jìn)行絕緣、吸收比、極化指數(shù)試驗(yàn)，為系列絕緣試驗(yàn)提供前期準(zhǔn)確判斷。</p><p

校準(zhǔn)這些儀器時(shí)的一個(gè)主要問(wèn)題是找到合適的電阻器，當(dāng)然是首先要足夠精確；還需要電阻值足夠大，使其能夠承受高直流電壓。此外，對(duì)于應(yīng)該采用什么樣的電阻值來(lái)進(jìn)行校準(zhǔn)，兆歐表制造商并沒(méi)有統(tǒng)一的標(biāo)準(zhǔn)，所以就需要各種各樣的電阻值。通過(guò)了解各種不同的絕緣測(cè)試儀，可以知道它們需要不同的性能檢查點(diǎn)。例如，某個(gè)測(cè)試儀需要測(cè)試50kΩ，而另一款測(cè)試儀則需要測(cè)試60kΩ，再一款又需要測(cè)試100
