Ko te taura ārai, e ai ki te ingoa, he taura ārai-aukati hikohiko o waho, he mea hanga hei taura tuku me te paparanga ārai. Ko te mea e kiia nei ko te "ārai" i runga i te hanganga taura he mahi anō hoki hei whakapai ake i te tohatoha o ngā mara hiko. Ko te arataki o te taura he mea hanga mai i ngā aho waea maha, he ngāwari ki te hanga i tētahi āputa hau i waenganui i a ia me te paparanga ārai, ā, kāore te mata o te arataki i te maeneene, ka hua ake te kukū o te mara hiko.
1. Paparanga ārai taura
(1). Tāpirihia he paparanga ārai o te rauemi haurua-arataki ki te mata o te arataki, he rite te kaha ki te arataki kua āraia, ā, he pai te hononga ki te paparanga ārai, kia kore ai e puta he rerenga hapa i waenga i te arataki me te paparanga ārai. E mōhiotia ana hoki tēnei paparanga ārai ko te paparanga ārai o roto. Tērā pea he āputa i te hononga i waenga i te mata ārai me te hipoki, ā, ina piko te taura, ka ngāwari te pakaru o te mata ārai taura pepa-hinu, arā, ngā āhuatanga e puta ai he rerenga hapa.
(2). Tāpirihia he paparanga ārai o te rauemi haurua-arahi ki te mata o te paparanga ārai, he pai te hononga ki te paparanga ārai kua āraia, ā, he ōrite te kaha ki te uhi whakarewa, kia kore ai e puta he rerenga haurua i waenga i te paparanga ārai me te uhi.
Hei kawe ōrite i te matua me te ārai i te papa hiko, ko ngā taura hiko ngaohiko reo-rahi me te ngaohiko teitei 6kV me runga ake he paparanga ārai arataki me he paparanga ārai ārai, ā, ko ētahi taura ngaohiko-iti kāore he paparanga ārai. E rua ngā momo paparanga ārai: te ārai haurua-arataki me te ārai whakarewa.
2. Taura ārai
Ko te paparanga ārai o tēnei taura he mea whiri ki roto i tētahi whatunga waea whakarewa, i tētahi kiriata whakarewa rānei, ā, he maha ngā momo huarahi mō te ārai kotahi me te ārai maha. Ko te ārai kotahi e pā ana ki tētahi kupenga ārai kotahi, ki tētahi kiriata ārai rānei, ka taea te takai i tētahi waea, neke atu rānei. Ko te aratau ārai maha he maha ngā whatunga ārai, ā, kei roto i te taura kotahi te kiriata ārai. Ko ētahi e whakamahia ana hei wehe i te pokanoa hikohiko i waenga i ngā waea, ko ētahi he ārai paparua e whakamahia ana hei whakapakari i te pānga ārai. Ko te tikanga o te ārai ko te whenua i te paparanga ārai hei wehe i te ngaohiko pokanoa i puta mai i te waea o waho.
(1). Parenga ā-haurua-arataki
Ko te paparanga ārai haurua-arataki he mea whakarite i runga i te mata o waho o te matua waea arataki me te mata o waho o te paparanga whakamarumaru, e kiia ana ko te paparanga ārai haurua-arataki o roto me te paparanga ārai haurua-arataki o waho. Ko te paparanga ārai haurua-arataki he mea hanga mai i tētahi rauemi haurua-arataki he iti rawa te ātete me te matotoru angiangi. Ko te paparanga ārai haurua-arataki o roto he mea hanga hei whakataurite i te papa hiko ki runga i te mata o waho o te matua arataki, hei karo i te tukunga wāhanga o te arataki me te whakamarumaru nā te mata koretake o te arataki me te āputa hau i puta mai i te matua kua taka. Kei te pai te pa o te ārai haurua-arataki o waho ki te mata o waho o te paparanga whakamarumaru, ā, he ōrite te kaha ki te uhi whakarewa hei karo i te tukunga wāhanga me te uhi whakarewa nā ngā hapa pēnei i te pakaru i runga i te mata whakamarumaru taura.
(2). Te whakangungu rakau whakarewa
Mō ngā taura hiko ngaohiko waenga me te iti, kāore he uhi whakarewa, hei tāpiri atu ki te whakatakoto i tētahi paparanga parepare haurua-arataki, tāpirihia hoki he paparanga parepare whakarewa. Ko te paparanga parepare whakarewa he mea takai noa iho erīpene parahihe waea parahi rānei, ko tāna mahi matua he tiaki i te papa hiko.
Nā te nui o te iahiko e puta ana i te taura hiko, ka puta te papa aukume huri noa i te iahiko, kia kore ai e pā ki ētahi atu wāhanga, nō reira ka taea e te paparanga ārai te ārai i tēnei papa aukume i roto i te taura. Hei tāpiri, ka taea e te paparanga ārai taura te whai wāhi ki te tiaki whenua. Mena ka pakaru te matua o te taura, ka taea e te iahiko turuturu te rere i te taha o te rere ārai laminar, pērā i te whatunga whenua, hei tiaki haumaru. Ka kitea he nui tonu te mahi a te paparanga ārai taura.
