Sebenzisa inkinobho yokuxhumana engenakuthinta, engenazo izingxenye ezihambayo, engenakuguga, engenazo izinkinobho zokusondelana ze-elekthronikhi njengenkinobho yokusiza, ayikho inkinga yokuxhumana embi, isenzo esithembekile, ukusebenza akuthintwa yimvelo yangaphandle, impilo ende, ukuthembeka okuphezulu, ukuxazulula inkinga yokuxhumana engenakuthinta.

Sebenzisa ubuchwepheshe be-switch ye-zero ehambisanayo - ewelayo. Ukuxhumana okunamandla nokungaguquki kwe-circuit breaker ngaphansi kokulawulwa kohlelo lokulawula lwe-elekthronikhi, ingabe i-waveform ye-voltage yesistimu ingaguquka ezingeni ngalinye, ku-waveform yamanje kuya ku-zero lapho kuphuka, i-amplitude yamanje yokungena kanye ne-over voltage incane, ukunciphisa umthelela ekusebenzeni kwegridi kanye nemishini, futhi indlela yokusebenza kagesi kanye nokusebenza kwendlela yokusebenza kwentwasahlobo kungahlelelwe, kungakhiqiza i-amplitude ephezulu yamanje yokungena kanye ne-over voltage, Umthelela omkhulu kumagridi kagesi kanye nemishini.

Indlela yokusebenza kamazibuthe ehlala njalo ingasebenza ukuvula nokuvala kwendawo/kude, futhi ingasebenza ukuvala nokuvala isivikelo, ingavulwa ngesandla. Ngenxa yokuthi ukusebenza kwamandla adingekayo kuncane, ukusetshenziswa kwama-capacitor kokuphakelwa kwamandla okushintsha ngqo, isikhathi sokushaja i-capacitor sifushane, ugesi wokushaja uncane, ukumelana okunamandla komthelela, ngemuva kokunqanyulwa kwamandla kusengaba se-circuit breaker.

Izinkinga ezinkulu zendlela yokusebenza yamagnethi ehlala njalo yilezi:

Awukwazi ukuvala ngesandla, ekusebenzeni kokunikezwa kwamandla kunyamalale, amandla e-capacitor aphelile, uma i-capacitor ingashajwa, ayikwazi ukuvalwa ukusebenza;

Ukuvula ngesandla, isivinini sokuqala sokuvula kufanele sibe sikhulu ngokwanele, ngakho-ke sidinga amandla amaningi, ngaphandle kwalokho asikwazi ukusebenza;

Ikhwalithi yama-capacitor okugcina amandla ayilingani futhi kunzima ukuyiqinisekisa;

Kunzima ukuthola isici sesivinini sokuvula esifanele;

Kunzima ukwandisa amandla okuvula okukhiphayo kwendlela yokusebenza kamazibuthe ehlala njalo.
