Zinc Oxide Surge Arresters ndiyo inodzivirira yakanyanya kurwisa over-voltage munyika. Sezvo ZOSA resistors inogadzirwa ne zinc oxide mafirimu. Zinc Oxide SurgeArresters ine yakanaka voltage-ampere maitiro kana ichienzaniswa neSiC arresters, iri pamusoro-voltage uye ikozvino kuyerera kuri mu creased zvikuru uye zvakakonzera kuchinja kwakakosha kweZOSA maitiro.Iyo microns ampere degree ikozvino inoyerera chete apo ZOSA iri kushanda pasi pemazuva ose, asi huwandu hwemazuva ano huchava zviuru zve-am-peres apo ZOSA inomira pamusoro pe-voltage, nekuda kweZOSA yakanaka! non-linear characterizatios. Panguva iyoyo inenge iri nyaya yekurerutsira nyika pamusoro pe-voltage simba, saka izvo zvinogadzirisa zvinobudirira kukuvadza kune equiplments yekutumira uye shanduko.
