Incazelo emfushane:
I-GDYZ-302W Metal Oxide Arrester Tester yakhiwe i-host, i-detector, kanye ne-insulating rod. I-host ne-detector zisebenzisa ukuxhumana okungenantambo, ibanga lokuxhumana lingamamitha angu-30, i-host ingavula noma ivale kude ikhanda le-clamp le-detector ukuqedela inqubo yokuhlola, futhi i-host ingabonisa inani lokuhlola lamanje kanye nesimo sekhanda le-clamp ngesikhathi sangempela. I-detector isebenzisa i-micro motor ukushayela ukuvulwa noma ukuvalwa kwekhanda le-clamp. Ikhanda le-clamp lenziwe nge-permalloy yokusebenza okuphezulu, enekhono elikhulu lokulwa nokuphazamiseka futhi ayithinteki kalula amandla kazibuthe angaphandle. Ukucaca kufinyelela ku-1uA. I-detector ingaxhunywa ku-insulating rod ukuze kuhlolwe ama-zinc oxide surge arrester emigqeni yamandla aphezulu. Imitha ingasetshenziswa futhi njenge-ultra-high-precision clamp-on leakage current meter.
