I tēnei wā, ko ngā mahi matua hei whakaiti i te whakamahinga hiko ko:
Arotauhia ngā tawhā pūnaha tuku hiko. Ko ngā tawhā tuku hiko ngā mea matua e pā ana ki te whakamahinga hiko. Hei tauira, mō te oumu 60t, ina ko te ngaohiko taha tuarua ko te 410V, ā, ko te iahiko ko te 23kA, ka taea te whakaiti i te whakamahinga hiko o mua.
Kua whakamahia te hikohiko hiato wai-whakamatao. Ko te hikohiko hiato wai-whakamatao he momo hikohiko hou kua whakawhanakehia ki tāwāhi i ngā tau tata nei. Ko te hikohiko hiato wai-whakamatao he mea tito mai i te wāhanga ngongo maitai o runga-whakamatao wai-whakamatao me te wāhanga mahi karāhe o raro, ā, ko te wāhanga wai-whakamatao he tata ki te 1/3 o te roa o te hikohiko. Nā te mea kāore he waikura pāmahana teitei (waikura karāhe) i roto i te wāhanga ngongo maitai wai-whakamatao, ka whakaitihia te waikura o te hikohiko, ā, ka mau tonu te hononga pai o te wāhanga ngongo maitai wai-whakamatao ki te hopu. Nā te mea he momo wai-whakamatao te miro o te wāhanga wai-whakamatao me te wāhanga karāhe, he pumau tōna āhua, kāore he pakaru, ā, ka taea te tu atu i te taipana nui, ka whakapai ake i te kaha o te atanga hikohiko, ā, ka whakaitihia te whakamahinga hikohiko.
Kua whakamahia te tikanga ārai-waikura o te hiko rehu wai. Nā te whakamahinga o ngā hiko i roto i te tukanga whakarewa, kua whakamahia ngā tikanga hangarau o te rehu wai me te ārai i te waikura o te hiko rehu wai, arā, ka whakamahia te taputapu rehu wai mowhiti i raro i te kakau hiko hei rehu wai ki runga i te mata o te hiko, kia rere ai te wai i raro i te mata o te hiko, ā, ka whakamahia te paipa mowhiti hei pupuhi i te hau kōpeke ki te mata o te au i runga ake i te kōhao hiko o te taupoki oumu, kia whakakorikoria ai te rere o te wai. Mā te whakamahi i tēnei tikanga, kua tino heke te whakamahinga o te hiko maitai tana. Ko te hangarau hou tēnei e whakamahia tuatahitia ana i roto i te oumu hiko tino-teitei. He māmā, he ngāwari ki te whakahaere, ā, he haumaru hoki te tikanga rehu wai.
Hangarau paninga mata hiko. He tikanga māmā, he tikanga whai hua hoki te hangarau paninga hiko hei whakaiti i te whakapaunga hiko.
Ko ngā rauemi paninga hiko e whakamahia whānuitia ana ko te konumohe me ngā rauemi uku, he kaha te ātete ki te waikura i te pāmahana teitei, ā, ka taea te whakaiti i te whakapaunga waikura i te mata taha hiko.
Ka whakamahia te hiko tuku. Mā te hiko tuku ka tuku te hiko ki roto i te matū, ka taunekeneke te mata o te hiko ki te matū, kia pai ake ai te ātete o te hiko ki te waikura pāmahana teitei. Ka whakaitihia te whakamahinga hiko mā te 10% ~ 15% ki te whakataurite ki te hiko noa.
