變壓器繞組的直流電阻測(cè)試是變壓器在交接、大修和改變分接開(kāi)關(guān)后,的試驗(yàn)項(xiàng)目。在通常情況下,用傳統(tǒng)的方法(電橋法和壓降法)測(cè)量變壓器繞組以及大功率電感設(shè)備的直流電阻是一項(xiàng)費(fèi)時(shí)費(fèi)工的工作。為了改變這種狀況,縮短測(cè)量時(shí)間以及減輕測(cè)試人員的工作負(fù)擔(dān),本公司開(kāi)發(fā)了直流電阻快速測(cè)試儀。它采用全新電源技術(shù),具有測(cè)量迅速、體積小巧、使用方便、測(cè)量精度高等特點(diǎn)。是測(cè)量變壓器繞組以及大功率電感設(shè)備直流電阻的理想設(shè)備。 產(chǎn)品別名:變壓器直流電阻測(cè)試儀、直流電阻快速測(cè)試儀、直流電阻測(cè)試等等。
