1.Kulangiza mwamphamvu ogwira ntchito kuti awone zigawo zowotcherera molingana ndi malangizo ogwiritsira ntchito.Pambuyo pokonza zigawo zonse za batch, ziyenera kutumizidwa kwa oyendera kuti akawunike ntchito isanayambe.Mtsogoleri woyendera ali ndi udindo wowunika komaliza ndikulemba zotsatira
2.Kuti awonetsetse kuti ali ndi khalidwe labwino, ma RCD onse ndi RCBO ayenera kuyesa nthawi yawo yodutsa komanso yopuma malinga ndi ICE61009-1 ndi ICE61008-1.
3.Timayesa mosamalitsa machitidwe ogwiritsira ntchito ophwanya dera.Ma breakers onse akuyenera kupitilira kuchedwa kwakanthawi kochepa komanso kuyesa kwanthawi yayitali.
Kuchedwa kwakanthawi kochepa kumapereka chitetezo ku zochitika zazifupi kapena zolakwika.
Kuchedwa kwanthawi yayitali kumapereka chitetezo chokwanira.
Kuchedwa kwanthawi yayitali (tr) kumakhazikitsa nthawi yayitali yomwe woyendetsa dera azinyamula katundu wambiri asanadutse.Magulu ochedwetsa amalembedwa mumasekondi a kupitilira apo nthawi zisanu ndi imodzi ndi mlingo wa ampere.Kuchedwa kwa nthawi yayitali ndi chikhalidwe chosiyana cha nthawi yomwe nthawi yodutsa imachepa pamene ikuwonjezeka.
4.High Voltage Test pa Circuit Breaker ndi Isolators cholinga chake ndikuwunika momwe ntchito yomanga ndi yogwirira ntchito imapangidwira, komanso mawonekedwe amagetsi ozungulira omwe chosinthira kapena chophwanya ayenera kusokoneza kapena kupanga.
Mayeso a 5.Aging adatchedwanso kuyesa kwa mphamvu ndi kuyesa kwa moyo, kuonetsetsa kuti zinthuzo zimatha kugwira ntchito bwino mumkhalidwe wapamwamba wamagetsi panthawi yovomerezeka.Ma RCBO athu onse amtundu wamagetsi amayenera kudutsa mayeso okalamba kuti atsimikizire kudalirika kwakugwiritsa ntchito.
