Kugirango wirinde ikibazo cyo kumeneka, hiyongereyeho ishingiro ryaikirundo, guhitamo kurinda kumeneka nabyo ni ngombwa cyane.Dukurikije ibipimo ngenderwaho by’igihugu GB / T 187487.1, urinda kumeneka ikirundo cyumuriro ugomba gukoresha ubwoko B cyangwa ubwoko bwa A, butarinda gusa kumeneka kwa AC, ahubwo bukanarinda impanuka DC.Itandukaniro rinini hagati yubwoko B nubwoko A nuko Ubwoko B bwongeyeho uburinzi bwo kwirinda DC.Nyamara, kubera ingorane nimbogamizi zubwoko bwa B gutahura, abayikora benshi bahitamo ubwoko bwa A. Ingaruka nini yo kumeneka kwa DC ntabwo ari imvune yumuntu ku giti cye, ahubwo ni akaga kihishe katewe no kunanirwa kwicyuma cyambere cyo gukingira.Birashobora kuvugwa ko kurinda imyanda kurubu birinda ibirundo byihishe kurwego rusanzwe.
Andika A yameneka yamashanyarazi
A-A yameneka yumuzunguruko hamwe na AC yo kumeneka ya AC yameneka cyane ni kimwe mubijyanye nihame ryakazi (agaciro kavunitse gipimwa kuri zeru zikurikirana zahinduwe), ariko ibintu bya magneti biranga transformateur biratera imbere.Iremeza gutembera mu bihe bikurikira:
(a) Kimwe n'ubwoko bwa AC.
(b) Ibisigisigi bisigaye DC.
(c) Umuyoboro wa DC woroshye wa 0.006A urengerwa hejuru yumuriro wa DC usigaye.
Andika B yameneka yamashanyarazi —— (UBUSHINWA irashobora gukora Ubwoko bwa RCD B)
Ubwoko B yameneka yumuzunguruko irashobora kurinda byimazeyo ibimenyetso bya sinusoidal AC, guhindagura ibimenyetso bya DC nibimenyetso byoroshye, kandi bifite ibyangombwa bisabwa kurenza ubwoko bwa A bwamashanyarazi.Iremeza gutembera mu bihe bikurikira:
a) Kimwe n'ubwoko A.
b) Sinusoidal isigaye isimburana kuri 1000 Hz.
c) Umuyoboro wa AC usigaye urengerwa numuyoboro wa DC woroshye wikubye inshuro 0.4
d) Ibisigisigi bya DC bisigara byikubye inshuro 0,4 byapimwe byateganijwe bisigaye cyangwa DC yoroshye ya 10mA (niyo yaba nini).
e) Imiyoboro ya DC isigaye ituruka kumirongo ikurikira yo gukosora:
- ibice bibiri byigice cyikiraro gihuza umurongo kumurongo wa 2-, 3- na 4-pole isi yameneka.
- Kubintu 3-pole na 4-pole isi yamenetse kumuzunguruko, guhuza inyenyeri 3 igice cyangwa guhuza ikiraro 6 igice.
