上面介紹了六種接地：供電系統(tǒng)地、保護地、邏輯地、屏蔽地安全柵地、信號回路地。對這六種接地，各家有各家的要求，雖然大都強調(diào)一點接地，接地電阻必須小于1歐姆等，但具體內(nèi)容上差別很大，下面給出幾個例子介紹常遇到的接地要求和方法。
①供電系統(tǒng)地：在很多企業(yè)，特別是電廠、冶煉廠等，其廠區(qū)內(nèi)有一個很大的地線網(wǎng)，而通常供電系統(tǒng)的地是與地線網(wǎng)連在一起的。有的廠家強調(diào)計算機系統(tǒng)的所有接地必須和供電系統(tǒng)地以及其它（如避雷地）嚴格分開，而且之間至少應保持15m以上的距離。為了*防止供電系統(tǒng)地的影響，建議供電線線路用隔離變壓器隔開。
