Shuruudaha waxqabadka korantada ee ilaaliya kor u kaca 1. Ka hortag xiriir toos ah Marka ugu badnaan tamarta joogtada ah ee Uc ee ilaaliyaha qalliinka la heli karo uu ka sarreeyo qiimaha ac rms ee 50V, kuwani waa inay buuxiyaan shuruudaha soo socda. Si looga hortago xiriir toos ah (qaybaha korantada ee aan la geli karin), ilaaliyaha qalliinka waa in loo qaabeeyaa si aan qaybihiisa nool loo taaban karin marka lagu rakibo xaaladaha caadiga ah ee isticmaalka. Marka lagu daro difaaca qalliinka oo lagu tilmaamay mid aan la heli karin, ilaaliyaha qalliinka waa in loo qaabeeyaa si, marka la rakibo oo loo xiro isticmaalka caadiga ah, qaybaha nool waa inaan la heli karin, xitaa ka dib marka la kala diro qaybaha laga saari karo qalab la'aan. Xidhiidhka u dhexeeya terminalka dhulka iyo dhammaan qaybaha la heli karo ee ku xiran waa inay ahaataa mid aan yarayn. U hoggaansanaanta waxaa lagu hubiyaa imtixaanno. 2. Hadhaaga hadda (hadda hadhay) I_PE Dhammaan ilaaliyayaasha qalliinka leh ee leh terminaalka PE, I_PE waa in lagu cabbiraa dhammaan marinnada ilaaliyaha qalliinka ee ku xiran tamarta korantada tijaabada tixraaca (UREF) iyadoo la raacayo tilmaamaha soo saaraha. U hoggaansanaanta waxaa lagu hubiyaa imtixaan, kaasoo aan khuseyn SPD-yada ku xiran N-PE oo keliya. 3. Heerka ilaalinta korantada Kor Korontada xaddidan ee ilaaliyaha qalliinka 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 ilaaliyaha qalliinka shall be able to withstand the specified discharge current without unacceptable changes in its characteristics. In addition, the voltage switch-type ilaaliyaha qalliinka or combined ilaaliyaha qalliinka shall at least be able to cut off the freewheeling current of the dry rated short-circuit current I_SCCR. U hoggaansanaanta waxaa lagu hubiyaa imtixaanno.
