He wāhanga haumaru te waea whenua o tehua motuka, ā, ko tana mahi matua he hono i te anga o te motuka ki te whenua hei tiaki i te haumaru whaiaro me te ārai i te pakaru o te motuka i puta mai i te hiko pateko.
He whakaritenga motuhake ā GB/T 755 me GB/T 14711 mō te whakapūmau i te motuka, engari he ārai wera tāpiri kei te motuka, kua tāutahia rānei ki tētahi tāutanga me te ārai wera tāpiri, he ārai wera kua whakatauria rānei.Ngaohiko ACmēnā he iti iho i te 50V, he iti iho i te 120V te ngaohiko DC, e whakamahia ana rānei mō ngā ara iahiko SELV, me whai taputapu tiaki whenua motuhake katoa.
Te tae, te whānui, te whakapiri o te waea whenua o te motuka, te aukati i te waikura hiko, te aukati i te waikura me te hototahitanga o te kaiwhakahaere me ngā wāhanga whakapiri; Mō te motuka he iti iho i te 100kW te mana whakatauranga, he pūwāhi whenua, ina neke atu i te 100kW te mana whakatauranga o te motuka, me tāpiri e te motuka he taputapu whenua i runga i te pūtake o te taketake, ka whakatakotoria tika he pūwāhi whenua ki roto i te pouaka hononga motuka, ā, ko te pūwāhi whenua tāpiri ka whakatakotoria ki runga i te papa waewae o te anga motuka.
He mea nui te ātete whenua hei whakarite i te pono o te whenua o te motuka, kaua e neke atu i te 0.1 ohms te mea tika, mōwhenua motuka itiā, ka taea te hono tika i te whenua, ā, mō te tāutanga o ngā motuka nui, o ngā taputapu nui rānei, ka whai pūnaha whenua motuhake hei whakarite i te pono o tōna whenua.
Tuatahi, me whai paparanga ārai anō hoki te waea whenua hei ārai i te hē o te ia whenua; Tuarua, me kaha te waea whenua ki te tu atu i te rumaki o ngā wai tuku iho pērā i te wai me te kore e pirau, koinei hoki tētahi o ngā whakaritenga matua mō te arataki waea whenua; Tuatoru, i raro i te tikanga me hono pono te waea whenua ki te whenua, ki te pūnaha whenua rānei, ka taea te whakapai ake i te mahi whenua o te motuka mā te rumaki wai, inā koa, ki te rumaki tika te waea whenua ki te wai hei utu mō te whenua, he mārama kāore e taea.
Mō te tiaki whenua o te motuka, ka whakatutukihia ngā tohutohu me ngā whakaritenga taipitopito i roto i ngā paerewa ngaio, engari i roto i te tukanga tirotiro kounga me te tauira o te motuka, ka kitea tonutia ētahi take whakakorenga kāore i te tika, inā koa te hononga me te whakapiri i te waea whenua me te motuka, ā, ko te diameter o te waea whenua kāore e tutuki i ngā whakaritenga.
