幾乎所有的絕緣測(cè)試儀都采用直流電壓作為激勵(lì)，所以兆歐表校準(zhǔn)器的交流要求很少。許多兆歐表為兩端設(shè)備，它提供一個(gè)電壓，并測(cè)量由被測(cè)設(shè)備所決定的電流。量程達(dá)到1TΩ 以及更高的兆歐表通常具有第三個(gè)端子，稱為保護(hù)端（Guard），對(duì)于消除泄漏通路以及被測(cè)未知電阻Rx的并聯(lián)元件非常有用。保護(hù)端的目的是消除可能會(huì)產(chǎn)生的泄漏電流來選擇性地將輸出寄生電阻性元件的影響減小為零。 </p> <p>

直流高壓的產(chǎn)生一般有三種方法。***種手搖發(fā)電機(jī)式。目前我國生產(chǎn)的兆歐表約80%是采用這種方法(搖表名稱來源)。第二種是通過市電變壓器升壓，整流得到直流高壓。一般市電式兆歐表采用的方法。第三種是利用晶體管振蕩式或**脈寬調(diào)制電路來產(chǎn)生直流高壓，一般電池式的絕緣電阻表采用的方法。 </p> <p> <br /> </p> <p> <br
