Si'itaga puipuiga mana'omia fa'atinoga eletise 1. Taofi fesootaiga tuusao Afai e maualuga atu le maualuga o le malosi galue faifai pea Uc o le puipuiga o le si'isi'i avanoa e maualuga atu nai lo le tau ac rms o le 50V, o nei mea e tatau ona ausia manaoga nei. Ina ia puipuia le faʻafesoʻotaʻi tuusaʻo (vaega faʻatautaia e le mafai ona maua), e tatau ona mamanuina le puipuiga o le siʻitia ina ia le mafai ona paʻi i ona vaega ola pe a faʻapipiʻi i lalo o tulaga masani o le faʻaaogaina. I le faaopoopo atu i le puipuiga o le siʻitia o loʻo faʻavasegaina e le mafai ona maua, e tatau ona mamanuina le puipuiga o le siʻitia ina ia, pe a faʻapipiʻi ma faʻapipiʻi mo le faʻaoga masani, o vaega ola e le mafai ona maua, e tusa lava pe uma ona faʻaumatia vaega e mafai ona aveese e aunoa ma meafaigaluega. O le feso'ota'iga i le va o le 'ele'ele ma vaega uma e mafai ona fa'afeso'ota'i i ai e tatau ona maualalo le fa'alavelave. E siakiina le tausisia e suʻega. 2. A'ave totoe (residual current) I_PE Mo puipuiga uma o lo'o i ai fa'amau PE, o le I_PE e tatau ona fuaina i pito uma o le puipuiga o le si'itia o lo'o feso'ota'i atu i le paoa o le reference test voltage (UREF) e tusa ai ma fa'atonuga a le kamupani gaosi mea. E siakiina le tausisia e se suʻega, lea e le faʻaogaina i SPD e fesoʻotaʻi naʻo le N-PE. 3. Tulaga puipuiga malu i luga Ole voltage faatapulaaina ole puipuiga fa'aoso 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 puipuiga fa'aoso shall be able to withstand the specified discharge current without unacceptable changes in its characteristics. In addition, the voltage switch-type puipuiga fa'aoso or combined puipuiga fa'aoso shall at least be able to cut off the freewheeling current of the dry rated short-circuit current I_SCCR. E siakiina le tausisia e suʻega.
