Kereini Haereere Hiko Kotahi te Koki

Ko ngā kerēne kotahi-piko-runga e mahi ana i runga i ētahi mātāpono tino māmā engari he whai hua. Ko te tikanga matua he motuka hiko me te hiki matua, e hono ana ki te raro o te pou o te kerēne. Ka honoa te kurupae ki te motuka me te hiki mā roto i tana taraka neke. I runga i te momo kerēne kotahi-piko-runga, ka taea te whakauru ki te taura hiki waea, ki te mekameka hiki rānei. Ina whakaohohia te motuka, ka nekehia te hiki mā te whakamahi i te taraka, ā, ka huri te motuka, ka taea e te kaiwhakahaere te whakahaere tika i ngā nekehanga tika me te haumaru o te kerēne.

Ko ngā kerēne hiko kotahi-piko tetahi o ngā momo kerēne e whakamahia whānuitia ana mō ngā mahi ahumahi nā te mea he ngāwari ki te neke me te utu iti. He maha ngā wheketere, ngā whare putunga me ētahi atu wāhi whakaputa e kitea ana mō ngā mahi neke rauemi. I runga i ngā hiahia takitahi o ngā kaiwhakamahi me ngā whakaritenga hiki, ka taea e rātou te tuku penapena utu nui ake i roto i ngā āhuatanga maha. Ko ngā painga matua o ngā kerēne kotahi-piko ko:

Utu iti iho: Nā te mea he iti ake te maitai me ngā wāhanga e hiahiatia ana hei huihui me te whakahaere. Hei tāpiri, nā te ngāwari o te tikanga me te iti o te pokapū taumaha ka māmā ake ngā wāhanga o te motuka me te pūnaha whakahaere, ā, ka iti ake te utu whānui.
Te Āhuahira o te Nekeneke: He tino ngāwari te nekeneke o ngā kerēne kotahi-piko nā te mea he pai, he māmā hoki te hoahoa. He māmā ake te whakahaere me te nekeneke i ō rātou hoa takirua-piko, nō reira he iti ake te wā whakahaere.
Whānuitanga o ngā Whakamahinga: He kōwhiringa pai ngā kerēne kotahi-piko mō ngā mahi maha, mai i te kawe rauemi māmā ki ngā mahi uaua ake pērā i te whakarewa tika. Nā te maha o ngā whakamahinga ka pai mō ngā mahi maha e hiahia ana ki ngā otinga whai hua.

Mō te whakatau tere, tukuna mai ngā mōhiohio e whai ake nei:

1. Te kaha hiki o te kerēni
2. Te teitei o te hiki (mai i te papa ki te pokapū matau)
3. Te whānui (te tawhiti i waenganui i ngā ara e rua)
4. Ko te pūtake hiko i tō whenua. He 380V/50Hz/3P, he 415V/50Hz/3P rānei?
5. Te tauranga tata ki a koe
