型號CE-IT絕緣裝置測試儀是一種全自動(dòng),高敏感的設(shè)備,用于測試埋地管道絕緣和隔離管道過路套管,以確定其有效性。CE-IT有一個(gè)液晶讀數(shù)顯示被測絕緣體英語的條件。聽到聲音信號時(shí),CE-IT運(yùn)行,脈動(dòng)音測試周期完成時(shí)的速度增加。
工作原理:
The actual resistance of a buried insulator depends on many factors, such as the environment in which the joint is located. In a very low resistivity environment, the normal resistance measurement for an insulating joint may be as low as 0.5 ohm. 埋地絕緣裝置的真實(shí)電阻取決于許多因素,諸如絕緣裝置所處的環(huán)境。在一個(gè)非常低的電阻率的環(huán)境中,一個(gè)絕緣接頭的正常電阻測量值可能是低至0.5歐姆。
