    Buku Lotsogolera Kusankha Mndandanda wa Ma SPD a Makina Operekera Mphamvu

    Kukhazikitsa kwa SPD pamalo aliwonse oteteza mphezi, malinga ndi muyezo wa mawonekedwe amagetsi otsika, kugawa zida zamagetsi molingana ndi gulu lamagetsi opitilira muyeso, mulingo wake wamagetsi opirira kusinthasintha umatha kudziwa kusankhidwa kwa SPD. Malinga ndi muyezo wa mawonekedwe amagetsi otsika, kugawa zida zamagetsi molingana ndi gulu lamagetsi opitilira muyeso monga mulingo wa chizindikiro, mulingo wokweza, mulingo wogawa ndi wowongolera, mulingo wamagetsi. Mulingo wake wamagetsi opirira kusinthasintha ndi: 1500V, 2500V, 4000V, 6000V. Malinga ndi malo otetezedwa okhazikitsa zida ndi magetsi osiyanasiyana amagetsi osiyanasiyana, kuti mudziwe malo okhazikitsa a SPD amagetsi ndi mphamvu yogawa.
    Mtunda wokhazikitsa pakati pa SPD iliyonse ya mulingo usakhale woposa 10m, mtunda pakati pa SPD ndi zida zotetezedwa uyenera kukhala waufupi momwe zingathere, wosapitirira 10m. Ngati chifukwa cha malire a malo okhazikitsa, simungathe kutsimikizira mtunda wokhazikitsa, ndiye kuti muyenera kuyika gawo lolumikizira pakati pa SPD iliyonse ya mulingo, kuti SPD yotsatira itetezedwe ndi SPD ya kalasi yakale. Mu makina operekera magetsi otsika, kulumikiza inductor kumatha kukwaniritsa cholinga cholumikizira.
    SPD ya mfundo yosankha njira yoperekera magetsi
    Voliyumu yogwira ntchito yopitilira: yayikulu kuposa zida zotetezedwa, voliyumu yogwira ntchito yopitilira ya dongosololi.
    Dongosolo la TT: Uc≥1.55Uo (Uo ndi dongosolo la voltage yotsika mpaka voliyumu yopanda mzere)
    Dongosolo la TN: Uc≥1.15Uo
    Dongosolo la IT: Uc≥1.15Uo(Uo ndi dongosolo la voltage yotsika kupita ku voltage yolumikizira)
    Mlingo Woteteza Voltage: wocheperako kuposa kutchinjiriza kupirira mphamvu yamagetsi ya zida zotetezedwa
    Mphamvu yotulutsa mpweya yoyesedwa: imatsimikiziridwa malinga ndi momwe mphezi ilili pamalo omwe yayikidwa komanso malo otetezera mphezi.
