HD-86數字(zi)式跨(kua)步(bu)電(dian)壓定(ding)點(dian)儀是一臺(tai)集計算機技(ji)術、數字(zi)信(xin)號處理技(ji)術于(yu)一體(ti)的(de)具(ju)有(you)創新(xin)特色、高(gao)性能的(de)智能化儀表，主要用(yong)于(yu)地(di)下電(dian)力電(dian)纜(lan)（尤其(qi)是單芯高(gao)壓電(dian)纜(lan)）金屬護層接地(di)故障(zhang)的(de)定(ding)點(dian)，也可用(yong)于(yu)芯線接地(di)故障(zhang)的(de)輔助定(ding)點(dian)（在護層已經破壞的(de)情況(kuang)下）。CD-86數字(zi)式跨(kua)步(bu)電(dian)壓定(ding)點(dian)儀還可通過電(dian)流(liu)(liu)傳(chuan)感器在井孔中測量故障(zhang)電(dian)纜(lan)中的(de)阻性電(dian)流(liu)(liu)，對電(dian)纜(lan)故障(zhang)點(dian)進(jin)行分段定(ding)位。

HD-66超高(gao)壓電(dian)(dian)(dian)纜(lan)護層(ceng)故(gu)(gu)障(zhang)(zhang)(zhang)測距儀，能夠進行超高(gao)壓電(dian)(dian)(dian)纜(lan)護層(ceng)故(gu)(gu)障(zhang)(zhang)(zhang)測距，并為超高(gao)壓電(dian)(dian)(dian)纜(lan)護層(ceng)故(gu)(gu)障(zhang)(zhang)(zhang)定點(dian)提(ti)供高(gao)壓脈沖信號源，還可用于(yu)護層(ceng)直流(liu)耐壓試驗(yan)。HD-66與本公司生產的HD-86 電(dian)(dian)(dian)纜(lan)故(gu)(gu)障(zhang)(zhang)(zhang)跨步電(dian)(dian)(dian)壓定點(dian)儀配合使用，可以(yi)對電(dian)(dian)(dian)纜(lan)護層(ceng)故(gu)(gu)障(zhang)(zhang)(zhang)進行定點(dian)。
