GPAS for LV Ground Potential Overvoltage Attack

I-GPAS sisixhobo sokukhusela umbane esisebenza ngeendlela ezininzi nesisebenzayo esidibanisa umhlaba onokubakho wokucinezela uhlaselo kunye nokukhusela i-arc ye-fault. Inokunciphisa kakhulu umonakalo kunye neempembelelo zokuhlaselwa komhlaba okunokubakho kunye neempazamo ze-arc kwisixhobo xa zibonakaliswe kwiingozi zombane.

Xa umbane othe ngqo wenzeke, intonga yombane okanye inethiwekhi yokukhusela umbane idibaniswe, kwaye umbane onamandla okhoyo ugeleza kwigridi yomhlaba. Xa imigca yevoltage ephezulu ifumana i-overvoltage yombane, umbane wangoku uqukuqela kwigridi yomhlaba ngokubamba umbane. Xa izixhobo eziphazamisayo ezinamandla ezifana noomatshini be-welding zisebenza, ukuphazamiseka okunamandla okukhoyo okwenziwa ngabo kuya kuphinda kugeleze kwigridi yomhlaba. Isiseko esinamandla sangoku sinokubangela ukulahleka kwedatha, ukusetyenziswa kakubi kwezixhobo, ukukhubeka kwezixhobo, ukonakala kwe-insulation okanye ukutshisa kwiinkqubo zokubonelela umbane ophantsi.

I-GPAS inokuthembeka okuphezulu kunye nexesha elifutshane lesenzo, elinokuthi likwazi ukwahlula ngokufanelekileyo imisinga yombane ye-frequency high-frequency, ukuthintela imisinga yombane ekuhlaseleni inethiwekhi ekhuselayo ekhuselayo ukusuka kumnatha wokukhusela umbane wokumisa umbane, kwaye uphephe ngokufanelekileyo ukwenzeka kweengozi zemveliso yokhuseleko ezifana nemililo kunye nokudubula.
