Iimpawu zesi sixhobo sokulinganisa i-Insulation Resistance Measuring
1. Uluhlu lokumelana ne-Insulation 2TΩ@5kV
2. I-short-circuit current inokulungiswa ukuya kwi-3mA.
3. Ukubonisa ngokuzenzekelayo amaxabiso ovavanyo lwe-polarization index (PI) kunye ne-dielectric absorption ratio (DAR), enokuvavanya ukuvuza kwangoku kunye ne-capacitance.
4. Ukusebenza okugqwesileyo kokuchasana nokuphazanyiswa, ukuchaneka kovavanyo kunokuqinisekiswa nangona ukuphazamisa okwangoku kufikelela kwi-2mA.
5. Isampuli yokuvavanya i-capacitive ikhupha ngokukhawuleza ukuphepha ingozi yeentlantsi ezibangelwa ukukhutshwa okwenziwe ngexesha lokuvavanya ikhebula.
6. Isixhobo sinomsebenzi wokukhutshwa ngokuzenzekelayo, kwaye sinokubonisa i-voltage yokukhupha ngexesha langempela (kukho kwakhona imveliso ephuculweyo kunye nokukhutshwa ngokukhawuleza okuzimeleyo).
7. Iindidi ezi-2 zeendlela zokubonelela ngombane: xa usebenzisa ibhetri ye-lithium-ion, ubomi bebhetri ukuya kwiiyure ze-5 (2500V@100M test resistance).
8. Inokubizwa ngokusetyenziswa. Kwimeko yokusilela kwamandla, inokutshintsha ngokuzenzekelayo ukusuka kumbane we-AC ukuya kunikezelo lwamandla ebhetri.
