鉗(qian)形(xing)(xing)接(jie)(jie)(jie)地(di)電(dian)(dian)(dian)(dian)(dian)阻儀(yi)(yi)(yi)測量(liang)(liang)接(jie)(jie)(jie)地(di)電(dian)(dian)(dian)(dian)(dian)阻的(de)基本原理是(shi)測量(liang)(liang)回(hui)路電(dian)(dian)(dian)(dian)(dian)阻。鉗(qian)表(biao)的(de)鉗(qian)口部(bu)分由電(dian)(dian)(dian)(dian)(dian)壓線圈(quan)及電(dian)(dian)(dian)(dian)(dian)流線圈(quan)組成。電(dian)(dian)(dian)(dian)(dian)壓線圈(quan)提供激勵信(xin)號，并在(zai)被測回(hui)路上(shang)感應一個電(dian)(dian)(dian)(dian)(dian)勢(shi)E。在(zai)電(dian)(dian)(dian)(dian)(dian)勢(shi)E的(de)作用(yong)(yong)下將在(zai)被測回(hui)路產生電(dian)(dian)(dian)(dian)(dian)流I。鉗(qian)表(biao)對E及I進行測量(liang)(liang)，并通過下面的(de)公式即可得到(dao)被測電(dian)(dian)(dian)(dian)(dian)阻R。鉗(qian)形(xing)(xing)接(jie)(jie)(jie)地(di)電(dian)(dian)(dian)(dian)(dian)阻儀(yi)(yi)(yi)是(shi)廣泛應用(yong)(yong)于電(dian)(dian)(dian)(dian)(dian)力、電(dian)(dian)(dian)(dian)(dian)信(xin)、氣象、油田、建筑及工業電(dian)(dian)(dian)(dian)(dian)氣設備的(de)接(jie)(jie)(jie)地(di)電(dian)(dian)(dian)(dian)(dian)阻測量(liang)(liang)。鉗(qian)形(xing)(xing)接(jie)(jie)(jie)地(di)電(dian)(dian)(dian)(dian)(dian)阻儀(yi)(yi)(yi)在(zai)測量(liang)(liang)有回(hui)路的(de)接(jie)(jie)(jie)地(di)系(xi)統時，不(bu)需斷(duan)開(kai)接(jie)(jie)(jie)地(di)引下線，不(bu)需輔助電(dian)(dian)(dian)(dian)(dian)極，**快(kuai)速(su)、使(shi)用(yong)(yong)簡便。
