I-single-phase meter iyisidingo esikhethekile, efakwe ku-akhawunti yegesi kuhlelo lokuxhumana lwezintambo ezimbili nge-current alternating, lapho i-voltage evamile ingu-220 V.
Izinhlobo zama-single-phase meters
Amadivaysi ahlukaniswe ngo:
- I-single-phase single-rate meter - inani elilodwa lokulinganisa ugesi lisetshenziswe ngosuku;
- imitha eyodwa-yesilinganiso semitha - ngaphakathi kwezinsuku ezimbili izinkokhelo ezimbili zisetshenzisiwe ngokuya esikhathini sokuhamba - imini nobusuku.
Ixhuma imitha yesigaba esisodwa
Ngaphambi kokuxhuma imitha yesigaba esisodwa, kuzodingeka uzijwayele ngesifunda esivela emiyalweni yokusebenza, kanye nangemuva kwekhava lokugcina.
Ibhokisi lokugcina liqukethe oxhumana nabo abangu-4, okungukuthi:
- Isigaba sokufaka efulethini noma ekhaya kusuka kunethiwekhi yangaphandle;
- ukuphuma kwesigaba ngaphakathi kwendlu noma indlu;
- ukufaka okungenayo endlini noma ekhaya kusuka kunethiwekhi yangaphandle;
- phuma i-zero ngaphakathi kwendlu noma ekhaya.
Ngaphambi kwenqubo umshini onqanyuliwe, shintsha noma ama-plugs. Uma kwenzeka ikhebula lokufaka lifika kumitha, nqamula umugqa. Izintambo zixhunywe oxhumana nabo bemitha yesigaba esisodwa ngokulandelana okungenhla.
Isigaba esisodwa noma isigaba sesithathu sesiteji
I-meter yesigaba esithathu ihluke ngokuthi ifakwe emanenjini amathathu noma amathaya ane-current alternating, i-voltage ejwayelekile ngu-380 V.
Isigaba esisodwa nesigaba samamitha amathathu sinezicelo ezahlukene:
- Amamitha wesilinganiso esisodwa afakwe emafulethini, izindlu zokuhlala kanye nehhovisi, emakamelweni, emagaraji. Alula futhi alula ukusebenzisa, ungakwazi kalula ukuthatha ukufundwa kubo;
- Amamitha amathathu-amamitha afakwe emaqenjini ezimboni futhi
ezakhiweni lapho kulindeleke khona inani eliningi lamandla kagesi. Idivayisi yabo iyinkimbinkimbi kakhudlwana kunamadivaysi esigaba esisodwa, kodwa izilinganiso zabo zinembile kakhulu.
Amamitha amathathu wesigaba angaxhunyaniswa kwinethiwekhi eyodwa-yesigaba. Uma ucabangela umbuzo wokuthi iyiphi ibhethri engcono ukuxhuma indlu - isigaba esisodwa noma isigaba sesithathu, kunconywa ukuba uyeke ukukhetha kwakho okokuqala. Idivaysi yesigaba esithathu sinamandla kakhulu futhi idinga ukusabalalisa okuningi okwamanje. Ngaphezu kwalokho, ine-voltage ephakeme ngakho-ke iyingozi nakakhulu uma kwenzeka isigamu esifushane.
Ngakho-ke, uzokwazi ukukhetha uhlobo oludingekayo lwemitha yesigaba esisodwa efulethini lakho.
