Lenei MOV Stack / Durathan mo Lightning Arrester o le vaega autu o le uʻamea faʻamalosia oxide，o le durethan o vaega autu ia o tagata e puʻeina, o loʻo gaosia e mea faigata gaioiga ma sili atu ona lelei voltammetric uiga. Latou lautele faʻaaogaina i le puipuiga o eletise masini. Le aoga autu：e saoasaoa tali vave, lautele tafe ala i uiga, maualalo totoe totoe, ma itiiti leakage i lalo o masani tulaga faʻagaioiga. O le taimi nei o vaega taua i le arrester faʻaputuina ma faʻaaogaina i le eletise eletise lalolagi ma le agamalu. O le oloa e mafai ona faʻaaogaina mo le faia o uila tagata puʻeina mo le tufatufaina o le eletise, nofoaga eletise, ma uaea meatotino puʻeina ma isi
