Te Tikanga o te Tauira
02
Te kaupapa hua me ngā tikanga mahi
1.E tutuki ana i ngā whakamātautau SPD o te Akomanga II (8/20μs)
2. I runga i te hangarau konutea waikura
3. Mā te whakamahi i te 34S MOV, ka eke te mōrahi ki te 8/20 μ s 40kA
4. Kāore he rere tonu o te auau mana
5. Ko te pāmahana o te taiao mahi he -40°C ~ +80°C
6. He mea whiriwhiri te mahi tohu mamao.
7. Ina taka te hua, ka huri te matapihi matomato ki te whero, ā, ka whakaratohia e te tohu mamao te mahi whakaoho mamao

Ngā whakaaro mō te tāutanga
1. Manatokohia te whakakorenga katoa o te hiko i mua i te tīmatanga o te tāutanga. Ka tino rāhuitia te mahi i ngā pūnaha hiko e ora ana.
2. Mō te tiakitanga tino pai, whakauruhia he parenga iahiko nui e hono-raupapa ana (fius, breaker rānei) i mua i te taputapu pehi ngaru.
3. Me tino tutuki te whakaurunga o ngā waea ki te hoahoa kua whakaratohia:
- DC+ = Pūrua pai
- DC- = Pūrua kino
- PE = Whenua tiaki whenua
Me whakarite kia tika te tautuhi i te pūrua hei ārai i ngā hapa waea. Whai muri i te tāutanga, whakakahangia te pūnaha mā te hono i te taputapu tiaki (te kaipahua/fius) me te whakaū i ngā tohu mahi tika.
4. Whakaotihia te tāutanga mā te whakau i te kōwae ki tōna wāhi kua tohua, me te whakamana i te mahi a te pūnaha tiaki ngaru.
5. Whakatinanahia ngā tirotiro tiaki kua whakaritea, tae atu ki:
- Te tirotiro ā-kanohi i te tohu tātaritanga
- Manatoko i te tūnga whakapā o te whakaoho
Me whakakapi tonu ina kitea:
- Te whakamārama tohu hapa whero
- Whakahohenga tohu whakaoho
6. Ko ngā whirihoranga tiaki ngaru whakarara e hiahia ana:
- Te whakatinanatanga o te ara iahiko whakarara pono
- Ngā hononga kua tika te whakapiko
- Ngā kaiārahi roa-iti rawa
- Ine waea e tika ana (AWG)
- Te ara tika me te kore he piko koretake
