I-Lightning Arresters iyisivikeli esibalulekile ohlelweni lwamandla kagesi, oluzosetshenziselwa ukwenza sengathi amadivayisi amakhulu kagesi aphikisana ne-Over-Voltage.I-Zinc Oxide Arresters isebenzisa ama-zinc oxide varistors anezimpawu ezinhle ze-volt-ampere ezingezona izingqikithi zawo, ezibonisa ukumelana okuphezulu lapho uhlelo luphakeme i-boltage, eyamanje inezinga le-microamp kuphela; lapho i-voltage ingaphezu kwamandla, i-current ukuthi ngokusebenzisa i-zinc oxide varistors egijima phezulu, ingasheshe ikhulule amandla we-over-voltage, ngaleyo ndlela ibeke umkhawulo wamandla angaphezu kwamandla, okwamanje, i-zinc oxide varistor nayo inalezi zici zamandla amakhulu okuhamba, isivinini sokuphendula ngokushesha, isivinini sokuphendula okusheshayo, ukusebenza kahle kokuvikela nokunye. Amandla we-arresters ahlangabezana nezimfuneko ze-Standard IEC60099-4.
