Surge Protective Devices(Direct Current SPD)

Hmannak Kauhning

SPD cu 1000 volts tang grid voltage le 50/60HZ frequency a ngeimi low-voltage phawtzamhnak system phunkip caah aa tlak, cu hna cu cakuat le pehtlaihnak, tlanglawng lam, phaisa lei system, chiti chuahnak hmun, inn sangpi, inn le zung inn hna an si. Hi mei thazaang hmangtu hna i electric thilri (computer, thilri le thilri, innchung thilri, tbk.) hna kha meikhu nih a den hna, caan tawite chung mei a lin tukmi le a dang mei a lin tukmi rawhralnak in huhphenh awkah. Thilri le pumpak himnak kha zohkhenh. A ttha tukmi overvoltage kilvennak thilri a si.

A hrampi dirhmun le riantuan ning phunglam

Three-phase pali-wire system ah, huhphenhtu hna cu phase pathum wire le vawlei hri he aa pehtlaimi neutral wire karlak ah an i pehtlaih (a tanglei hmanthlak zoh). A tlangpi in thil sining ahcun, kilvengtu cu Levin dirhmun ah a um, cun mei vannak hri cu meikhu asiloah a dang a ruang ruangah a tthawng tukmi a si tikah. A huhphenhtu cu nanosecond caan chungah rang tein a on lai, vawlei ah a tthawnnak a luhter lai, cucaah mei hri cung i electric thilri pawl kha a huhphenh hna lai. Surge overvoltage nih huhphenhnak chungin a kal i a tlau tikah, huhphenhnak cu a sangmi ralchanhnak dirhmun ah a kir tthan. Power grid riantuan ning ttha tein a hnorsuan lonak hnga.
