Ko te pikinga ake o te hiahia mō te pūngao hiko hei tautoko i te whanaketanga o te ao e hiahia ana kia nui te haumitanga ki te whakaputa hiko. Heoi, hei tāpiri atu ki ngā mahere uaua mō te wā waenga me te wā roa, ka whakawhirinaki ēnei haumitanga ki ngā rauemi taiao, e
ka mimiti haere nā te pēhanga tonu ki te taiao. Nō reira, ko te rautaki pai rawa atu hei pupuri i te tuku pūngao mō te wā poto ko te karo i te moumou me te whakanui ake i te whai huatanga o te pūngao. He mahi nui tā ngā motuka hiko i roto i tēnei rautaki; nā te mea tata ki te 40%
e kiia ana ko te nui o te hiahia mō te pūngao o te ao e pā ana ki ngā tono mōtini hiko.
Nā te hiahia kia whakaitihia te whakapaunga pūngao me ngā tukunga hauhā waro, he maha ngā Kāwanatanga o te ao kua whakatakoto i ngā Ture ā-rohe, e mōhiotia ana ko te MEPS (Minimum Energy Performance Standards) ki ngā momo taputapu maha,
tae atu ki ngā motuka hiko.
Ahakoa he rerekē ngā whakaritenga motuhake o ēnei MEPS i waenga i ngā whenua, ko te whakatinanatanga o ngā paerewa ā-rohe pēnei i te ABNT,IEC,Mā te MG-1, e tautuhi ana i ngā taumata whai huatanga me ngā tikanga whakamātautau hei whakatau i ēnei whai huatanga, ka taea te whakapūmau i te whakamāramatanga, te ine me te hōputu whakaputanga mō ngā raraunga whai huatanga i waenga i ngā kaihanga motuka, kia māmā ake ai te kōwhiringa motuka tika.
te whai huatanga o te pūngao o ngā motuka toru-wāhanga ehara nei i te motuka parai, Ex eb ngā motuka haumaru kua whakanuia, ētahi atu rānei
ngā motuka e tiakina ana e te pahūtanga, me te putanga kua whakatauria he rite ki te 75 kW, neke atu rānei, ā, he rite ki te 200 kW, iti iho rānei, me
2, 4, 6 rānei ngā pou, me rite ki te iti rawaIE4taumata whai huatanga i whakatakotoria i roto i te Ripanga 3.
Hei whakatau i te iti rawa o te whai huatanga o ngā motuka 50 Hz me ngā putanga mana kua whakatauria PN i waenga i te 0,12 me te 200 kW kāore i whakaratohia i roto i ngā Ripanga 1, 2 me te 3, me whakamahi te tātai e whai ake nei:
ηn = A* [log1o(Pv/1kW)]3 + BX [log10(PN/1kW)]2 + C* log10(PN/1kW)+ D.
Ko A, B, C me D ngā taunga whakarara hei whakatau i runga anō i ngā Ripanga 4 me te 5.
