Voltage zero-kuyambuka kudzivirira tekinoroji, yekudzivirira relay muchigadzirwa.
Iyo nzira yekuchengetedzwa kwekuchengetedza ndeye: simba rekupa kune relay coil rinodzorwa ne-single-chip microcomputer, nekudaro ichidzora kuvharwa kweiyo relay contacts.Panguva imwecheteyo, iyo trigger point inoitika kuve zero voltage chinzvimbo che AC sine wave.Iyo relay contacts yakavharwa padhuze ne zero voltage chinzvimbo, iyo inogona kudzikisa arcing yevanobatika, nekudaro ichidzivirira relay kubva pakukanganisa kwemafungu makuru.

Bhuruu mutsetse- iyo sine wave yealternating current
Yellow line -icho chinokonzeresa kuti relay contact ivhare
1-1 The trigger point iri munharaunda ye zero-voltage
1-2 Trigger point inotsauka kubva ku zero voltage
Mhedziso
1-1 Pedyo nenzvimbo inokonzeresa uye zero voltage chinzvimbo, kana kubata kwavharwa, kurasikirwa kwemuviri kweiyo relay's pakarepo yakawandisa ikozvino inogona kudzivirirwa.
1-2 Kana kusangana kwavharwa, kune arc kubva kune zero voltage, ipapo kana iyo yekusangana yakavharwa, hapana relay kudzivirira.
Yedu ine hukama Voltage zero-muchinjika kudzivirira chigadzirwa chinyorwa:207C, 207HP, 207E,207F, 205C, 215C, 243C,217C, 251C, nezvimwewo.
