Si looga hortago dhibaatada daadinta, marka lagu daro dhulka la dhigodallacsiinta raso, doorashada ilaaliyaha daadinta ayaa sidoo kale aad muhiim u ah.Marka loo eego heerka qaranka GB/T 187487.1, difaaca daadinta tuubada dallacadu waa inay isticmaashaa nooca B ama nooca A, kaas oo aan kaliya ka ilaalinaynin daadinta AC, laakiin sidoo kale ka ilaalinaysa garaaca DC.Farqiga ugu weyn ee u dhexeeya Nooca B iyo Nooca A waa in Nooca B uu ku daray ilaalinta ka hortagga daadinta DC.Si kastaba ha ahaatee, sababtoo ah caqabadaha adag iyo caqabadaha kharashka ee nooca B, soo saarayaasha intooda badani waxay hadda doortaan nooca A. Dhibaatada ugu weyn ee daadinta DC maaha dhaawaca shakhsi ahaaneed, laakiin khatarta qarsoon ee ay sababtay fashilka qalabka ilaalinta asalka ah.Waxaa la odhan karaa ilaalinta daadinta hadda ee xajmigu waxay leedahay khataro qarsoon heerka caadiga ah.
Nooca A wareegga wareegga dillaaca
A-nooca wareegga wareegga wareegga qulqulka iyo nooca AC-ga dareeraha wareegga wareegga asal ahaan waa isku mid marka la eego mabda'a shaqada (qiimaha daadinta waxaa lagu cabbiraa wareegga eber ee hadda jira), laakiin astaamaha magnetic ee beddelka ayaa la hagaajiyay.Waxay xaqiijisaa ku dhaca xaaladaha soo socda:
(a) La mid ah nooca AC.
(b) Hadhaaga garaaca wadnaha DC.
(c) Dhaqdhaqaaqa siman ee DC ee 0.006A ayaa lagu dulsaaray hadhaaga garaaca wadnaha DC hadda.
Nooca B ee wareegga wareegga dillaaca -- (CHINAEVSE wuxuu samayn karaa RCD Nooca B)
Nooca B ee wareegga wareegga wareegga wuxuu si kalsooni leh u ilaalin karaa calaamadaha sinusoidal AC, garaaca calaamadaha DC iyo calaamadaha siman, waxayna leeyihiin shuruudo naqshadeed oo ka sarreeya nooca A.Waxay xaqiijisaa ku dhaca xaaladaha soo socda:
a) La mid ah nooca A.
b) Haraaga sinusoidal beddelka hadda jira ilaa 1000 Hz.
c) Hadhaaga AC hadda waxa lagu dulsaaray koronto siman oo DC ah oo 0.4 jeer ka badan inta hadda la qiimeeyay
d) Hadhaaga garaaca wadnaha DC ee hadda waxa lagu sarraysiiyay 0.4 jeer inta hadda la qiimeeyay ama hadda siman oo DC ah oo ah 10mA (hadba ka weyn).
e) Hadhaaga qulqulka DC ee ay abuuraan wareegyada hagaajinta ee soo socda:
- laba buundada isku xirka mawjadda nus-mawjadaha xariiqda loogu talagalay 2-, 3- iyo 4- cirifka wareegga wareegga wareegga.
- Wixii 3-cirif ah iyo 4-cirif ah oo wareegyada wareegga wareegga ah ee daadinta dhulka, 3 isku xirka xiddigta-mawjadaha ama 6 isku xirka buundada badhka
