HE AHA NGĀ MAHI A TE PĀNUI UTA NGAOHI TEITEI?

Ko te pana kawenga ngaohiko-tiketike he taputapu hiko ngaohiko-tiketike kua whakakotahihia, kei roto ko te pana wehe, he fiusi, he whakawhiti wera, he tuku whakawhiti me te taputapu tinei pewa.

He taputapu tinei pewa ngāwari tō te pana kawenga ngaohiko-tiketike, ka taea anake te whakamahi hei hanga me te wawahi i te ia kawenga noa, ā, kāore e taea te whakamahi hei wawahi i te ia ara-poto. Nō reira, he maha ngā wā ka honoa te pana kawenga ngaohiko-tiketike ki te fiusi ngaohiko-tiketike me te tuku wera, ā, ka whakamahia te fiusi hei tapahi i te ia ara-poto i te wā ara-poto. Mēnā ka nui rawa te uta, ka mahi te tuku wera ki te whakaweto aunoa i te pana kawenga. Nā te mea he āputa mārama kei te momotuhia te pana kawenga, he mahi anō hoki tāna ki te wehe i te pūtake hiko hei whakarite i te tiaki haumaru.

He pai ngā pana kawenga ngaohiko teitei me ngā taputapu hiko whakakotahi mō ngā pūnaha hiko AC-wāhanga-toru 10 kV, 50 Hz, e whakamahia ana rānei me ngā huinga taputapu tohatoha hiko katoa, ngā kāpata pana whatunga mowhiti, ngā teihana whakauru, me ētahi atu, ā, e whakamahia whānuitia ana i roto i ngā kaupapa hanga me te whakahou whatunga rohe, ngā umanga ahumahi me te keri, ngā whare teitei me ngā whare tūmatanui, me ētahi atu, ka taea te whakamahi hei puna hiko whatunga mowhiti, hei pūrua rānei, ā, ka takaro i te tūranga tohatoha hiko, whakahaere me te tiaki. He painga ōna ko te kaha pakaru nui, te haumaru me te pono, te roa o te ora hiko, te mahi auau, te hanganga kiato, te rahi iti, te mama, me te kore tiaki. Me te pakaru o te iahiko whakatauranga, te iahiko taumaha. Ka taea e ia te pakaru i te iahiko poto-porowhita me te aukati i te mahi a ngā taputapu mai i te kore o te āputa. He whati wehewehe te pana. He pūnaha puna hiko o te pana whenua me te kaha kati, ka taea te whakahaere mamao.

Ko te pana uta (QL) he taputapu pana e hāngai ana ki te hanga me te wawahi i ngā iahiko uta. He taputapu tinei pewa ngāwari tō te pana uta ngaohiko-tiketike me te pūwāhi momotu mārama, ka taea te tahuri me te whakaweto i te iahiko uta me te iahiko taumaha, ā, he mahi anō hoki hei pana wehe, engari kāore e taea te momotu i te iahiko poto-ara iahiko. I te nuinga o te wā, ka whakamahia te wheketere pana uta me ngā fiusi hei tapahi i te iahiko hapa mā te āwhina o ngā fiusi, ka taea te whakamahi whānui i roto i te hanga anō i te whatunga hiko tāone me te taiwhenua. Ko te nuinga e whakamahia ana mō te whatunga hiko 6~10kV.

E ai ki te momo tinei pewa, ka wehea te pana kawenga ngaohiko-tiketike ki te momo whakaputa hau, te momo hau kōpeke, te momo korehau me te momo SF6. E ai ki te wāhi tāutanga, ka wehea ki ngā wāhanga e rua: te momo o roto me te momo o waho.

He māmā te hanganga o te pana kawenga, he iti te rahi, he iti hoki te utu, ā, he pai mō ngā wā kāore e hiahiatia he hinu, kāore he tiaki, me ngā mahi auau. Mēnā ka honoa ki ngā fiusi, ka taea te whakamahi hei pana hiko mō ngā kaiwhakamahi he iti, he iti rānei te kaha ki te whakakapi i ngā kaiwawao ara iahiko. Ka tīpakohia te pana kawenga i runga i te ngaohiko whakatauranga me te iahiko whakatauranga, ā, ka tirohia mō te pēhi me te pumau o te wera. Mēnā he fiusi kei a ia, me manatoko te kaha pakaru o te fiusi, ā, kāore pea e manatokohia tōna pumau hihiri me te pumau o te wera.
