    I-SPD Yomhlahlandlela Wokukhetha Wochungechunge Lwesistimu Yokunikezela Amandla

    Ukufakwa kwe-SPD endaweni ngayinye yokuvikela umbani, ngokwezinga lokubukeka kukagesi wamandla aphansi, kwenza ukuhlukaniswa kwezinto zikagesi ngokuhambisana nesigaba samandla kagesi angaphezulu, ukwahlukanisa kwawo ukumelana nezinga lamandla kagesi kunganquma ukukhethwa kwe-SPD.Ngokwezinga lokubukeka kukagesi wama-voltage aphansi, hlukanisa izinto zikagesi ngokuhambisana nesigaba se-over voltage njengeleveli yesiginali, izinga lokulayisha, izinga lokusabalalisa kanye nokulawula, izinga lokuphakelwa kwamandla.I-insulation yayo imelana ne-impulse voltage level yile: 1500V, 2500V, 4000V, 6000V.Ngokwesikhundla sokufakwa kwemishini evikelekile ehlukile kanye nombani ohlukile wendawo yokuvikela umbani, ukunquma indawo yokufaka ye-SPD yokunikezwa kwamandla kanye nomthamo wokunqamuka.
    Ibanga lokufaka phakathi kwe-SPD yezinga ngalinye akufanele libe ngaphezu kuka-10m, ibanga phakathi kwe-SPD nezinto ezivikelwe kufanele libe lifushane ngangokunokwenzeka, lingabi ngaphezu kuka-10m.Uma ngenxa yomkhawulo wendawo yokufaka, ingakwazi ukuqinisekisa ibanga lokufaka, ngakho-ke udinga ukufaka ingxenye yokuhlukanisa phakathi kweleveli ngayinye ye-SPD, yenza i-SPD yekilasi yangemuva ivikelwe i-SPD yekilasi langaphambili.Kuhlelo lokunikezwa kwamandla kagesi ophansi, ukuxhuma i-inductor kungafeza injongo yokuhlukanisa.
    I-SPD yomgomo wokukhetha ukucaciswa kwesistimu yokunikezwa kwamandla
    Ubukhulu.I-voltage yokusebenza eqhubekayo: inkulu kunempahla evikelwe, ubuningi besistimu.i-voltage yokusebenza eqhubekayo.
    Isistimu ye-TT: Uc≥1.55Uo (I-Uo iyisistimu ye-voltage ephansi ukuya ku-null line voltage)
    Isistimu ye-TN: Uc≥1.15Uo
    Isistimu ye-IT: Uc≥1.15Uo(I-Uo iyisistimu ye-voltage ephansi ukuya kumugqa womugqa)
    I-Voltage Protection Level: ingaphansi kokufakwa kwe-insulation ukumelana nomfutho we-voltage wemishini evikelwe
    Isilinganiso sokukhishwa kwamanje: kunqunywa ngokwesimo sombani sendawo efakiwe nendawo yokuvikela umbani.
