Impendulo: Izinto zinezici zokukhula nokuncipha kokushisa, futhi ubude bebha yebhasi buzoshintsha ngenxa yokushisa ngesikhathi sokusebenza. Ukuze kugwenywe ukucindezeleka okukhulu nomonakalo kubha yebhasi kanye nesivikelo esisekelayo ngenxa yezinguquko ekukhuleni nasekuncipheni kokushisa, amajoyinti okunweba kufanele afakwe kubha yebhasi eqinile.

49. Liyini izinga lokunciphisa ikhoyili yokucindezela i-arc futhi liyini i-residual current?

Impendulo: Isilinganiso somehluko phakathi komshini wokungenisa kanye nomshini wokukhipha wekhoyili yokucindezela i-arc kanye nomshini wokukhipha wegridi yamandla sibizwa ngokuthi izinga lokunciphisa. Ngemva kokuba umshini wokungenisa wekhoyili yokucindezela i-arc ubuyisela ugesi wokukhipha, umshini wokukhipha ohamba endaweni yokumisa ubizwa ngokuthi umshini wokukhipha ohlala njalo.

50. Uma uhlelo olunephuzu elingathathi hlangothi elisekelwe ku-coil yokucindezela i-arc lusebenza ngendlela evamile, ingabe i-coil yokucindezela i-arc ine-voltage?

Impendulo: Uma uhlelo lusebenza ngokujwayelekile, ngenxa yomthamo wesigaba sesithathu kuya phansi ongalingani womugqa, kuba ne-voltage ethile phakathi kwephuzu elingathathi hlangothi lenethiwekhi nomhlabathi, futhi inani le-voltage lihlobene ngqo nokungalingani kwe-capacitance. Ngaphansi kwezimo ezijwayelekile, i-voltage ekhiqizwa yiphuzu elingathathi hlangothi ayikwazi ukudlula u-1.5% we-voltage yesigaba esilinganisiwe.
