Hauv kev ntsuas qhov ntsuas, qhov ntsuas qhov tsim nyog yuav tsum raug xaiv raws li qhov teeb meem tshwj xeeb. Lub hauv paus ntsiab lus ntawm qhov ntsuas hluav taws xob yog:
1 Qhov ntau ntawm cov ntsuas voltage yog ib qho tseem ceeb rau kev xaiv qhov ntsuas qhov hluav taws xob, yog li yuav tsum muaj ntau yam txaus ntsuas ntawm qhov ntsuas ntsuas;
2 yuav tsum muaj ntau yam khoom txaus thiab muaj txaus ntsuas kev ntsuas;
3 muaj peev xwm nkag siab txaus impedance, lub tswv yim tsis kam ntawm qhov voltage sensor yog qhov kev thauj khoom ntxiv ntawm Circuit Court nyob rau hauv kev xeem, kom txo tus cawv ntawm kev nkag ntawm Circuit Court hauv Circuit Court nyob rau hauv kev xeem, nws yuav tsum muaj ib siab dua tswv yim impedance;
4 yuav tsum muaj peev xwm tiv thaiv tsis tau; tus ntsuas voltage feem ntau muaj qee cov suab nrov nrov thiab lwm yam khoom uas tsis tas yuav tsum ntsuas.
