He aha te Pūrere Utu? He aha ngā Mahi Tiaki kei a ia?

 Ko te waeine utu te waeine whirihoranga tino nui o te pūtake hiko. Ko ōna mahi tiaki e whakaatahia ana i roto i ngā āhuatanga o te tiaki i te ngaohiko tāuru ki runga/ki raro, te tiaki i te ngaohiko tāuru ki runga/ki raro, te whakaoho tiaki i te ngaohiko tāuru ki runga/ki raro, te whakahokinga ara iahiko poto, me ētahi atu.

1. He aha te waeine utu?

1) Ka whakamahia e te waeine utu he tikanga whakamarara wera e whakakotahi ana i te whakamatao-ā-roto me te whakamatao-hau, ā, ka whakahaere i te whakamatao-ā-roto i te kawenga māmā, e hangai ana ki te mahi tuturu o te pūnaha hiko.

2) Koinei te kōwae whirihoranga tino nui o te pūtake hiko, ā, e whakamahia whānuitia ana i roto i te pūtake hiko o ngā teihana hiko mai i te 35kV ki te 330kV.
2. Mahi tiaki o te waeine utu ahokore

1) Te tiaki i te ngaohiko tāuru ki runga/ki raro

Kei te kōwae te mahi tiaki ngaohiko tāuru ki runga/ki raro. Ina iti iho te ngaohiko tāuru i te 313±10Vac, ina nui ake rānei i te 485±10Vac, kua tiakina te kōwae, kāore he putanga DC, ā, kei te kā te tohu tiaki (kōwhai). Kia hoki te ngaohiko ki waenganui i te 335±10Vac～460±15Vac, ka tīmata aunoa te kōwae ki te mahi.

2) Whakaoho parenga ngaohiko nui/ngaohiko iti putanga

Kei te kōwae te mahi tiaki i te ngaohiko putanga me te whakaoho ngaohiko iti. Ina nui ake te ngaohiko putanga i te 293±6Vdc, kua tiakina te kōwae, kāore he putanga DC, ā, kei te kā te tohu tiaki (kōwhai). Kāore e taea e te kōwae te whakaora aunoa, ā, me whakaweto te kōwae, kātahi ka whakakā anō. Ina iti iho te ngaohiko putanga i te 198±1Vdc, ka whakaoho te kōwae, kei reira te putanga DC, ā, kei te kā te tohu tiaki (kōwhai). I muri i te whakahokinga mai o te ngaohiko, ka ngaro te whakaoho ngaohiko putanga kōwae.

3. Te whakahokinga poto-ara iahiko

He mahi whakahoki poto-ara iahiko kei te kōwae. Ina poto-ara iahiko te putanga o te kōwae, kāore te iahiko putanga e neke atu i te 40% o te iahiko whakatauranga. I muri i te whakakorenga o te tauwehenga poto-ara iahiko, ka whakahokia aunoatia e te kōwae te putanga noa.

4. Te tiaki i te ngaronga o te wāhanga

He mahi tiaki i te ngaronga ā-wāhanga kei roto i te kōwae. Mēnā kāore te ā-wāhanga whakauru, ka whakawhāitihia te mana o te kōwae, ā, ka taea te haurua te utaina o te putanga. Mēnā he 260V te ngaohiko putanga, ka puta he iahiko 5A.

5. Te tiaki i te pāmahana nui

Ina āraia te putanga hau o te kōwae, ina teitei rawa rānei te pāmahana o te taiao, ā, ka nui ake te pāmahana i roto i te kōwae i te uara kua whakaritea, ka tiakina te kōwae mai i te pāmahana nui rawa, ka kā te tohu tiaki (kōwhai) i runga i te panera kōwae, ā, kāore he putanga hiko o te kōwae. Ina whakakorea te āhua rerekē, ā, ka hoki te pāmahana i roto i te kōwae ki te āhua noa, ka hoki aunoa te kōwae ki te mahi noa.
6. Te parenga o te aukume taha tuatahi

I roto i te āhua rerekē, ka puta te iahiko nui rawa atu i te taha whakatikatika o te kōwae, ā, ka tiakina te kōwae. Kāore e taea e te kōwae te whakaora aunoa, ā, me whakaweto te kōwae, kātahi ka whakakā anō.
