Zofunikira pakuchita ntchito kwamagetsi kwachitetezo cha Surge 1. Pewani kukhudzana mwachindunji Pamene mphamvu yayikulu yopitilirabe yogwira ntchito ya Uc yachitetezo chopezeka ndi ma 50V ac rms, izi zikwaniritsa zofunika izi. Kuti mupewe kukhudzana mwachindunji (zigawo zosafikirika), chitetezo chachitetezo chidzapangidwa kuti magawo ake amoyo asakhudzidwe akayikidwa pansi pamikhalidwe yogwiritsiridwa ntchito. Kuphatikiza pa chitetezo cha opaleshoni chomwe chimatchedwa kuti sichingafikike, chitetezo cha opaleshoni chidzapangidwa kuti, chikaikidwa ndi waya kuti chigwiritsidwe ntchito bwino, ziwalo zamoyo sizidzakhala zotheka, ngakhale zitatha kuchotsa mbali zomwe zingathe kuchotsedwa popanda zida. Kulumikizana pakati pa malo oyambira pansi ndi magawo onse ofikirika olumikizidwa nawo kuzikhala kocheperako. Kutsatira kumawunikiridwa ndi mayeso. 2. Mphamvu yotsalira (yotsalira) I_PE Kwa onse oteteza maopaleshoni okhala ndi ma PE terminals, I_PE idzayezedwa ndi ma terminals onse achitetezo opangira opaleshoni olumikizidwa ndi magetsi a test voltage test (UREF) molingana ndi malangizo a wopanga. Kutsatira kumawunikiridwa ndi mayeso, omwe sagwira ntchito kwa ma SPD olumikizidwa ku N-PE yokha. 3. Voltage chitetezo mlingo Up Kuchepetsa mphamvu yamagetsi ya chitetezo champhamvu should not exceed the voltage protection level specified by the manufacturer. Compliance is checked by tests. 4. Action load test When the maximum continuous working voltage Uc is applied, the chitetezo champhamvu shall be able to withstand the specified discharge current without unacceptable changes in its characteristics. In addition, the voltage switch-type chitetezo champhamvu or combined chitetezo champhamvu shall at least be able to cut off the freewheeling current of the dry rated short-circuit current I_{Mtengo wa SCCR}. Kutsatira kumawunikiridwa ndi mayeso.
