Māhele Puʻupuʻu Uila (LPZ)
Ma ka moʻomeheku'IEC,ʻo nā hua'ōlelo likeʻole me ka 1 / 2 / 3 a iʻole ka papa inoa 1 / 2 / 3 e piʻi nei i kahi mea palekana. Ma kēiaʻatikala, e hoʻomaka ana mākou e hoʻokomo i kahi manaʻo e pili ana i nā hua'ōlelo mua: ka'āpana pale uila a LPZ paha.
He aha ka lae hoʻomalu uila a no ke aha i kū ai?
Kuhi ʻia ka manaʻo uila uila e wehewehe i ke kumu IEC 62305-4, kahi kūhelu honua no ka palekana o ka uila. Hoʻokumu ʻia ka manaʻo LPZ ma ka manaʻo e hoʻolōʻihi i ka ikehu uila i kahi pae palekana i ʻole ka hoʻolau ʻole i ka hana hōʻino ma ka mīkini.
E ʻike i kahi moʻoʻōlelo maʻamau.
No laila he aha keʻano o ka palekana palekana?
LPZ 0A: He kahua paʻa ʻole ma waho o ka hale e hōʻike ʻia ana a na ke kiko uila. Ma LPZ 0A, ʻaʻohe pale e pale aku ai i ka pulehu o ka wawa o ka uila LEMP (Lightning Electromagnetic Pulse).
LPZ 0B: E like me LPZ 0A, aia ma waho o ka hale a aia ka LPZ 0B i ka palekana e ka papa hana uila i waho, ma loko o kahi pale o ke koʻokoʻo uila. Eia hou,ʻaʻohe pale pale kū'ē iā LEMP.
LPZ 1:ʻO kaʻaoʻao i loko o ka hale. Ma kēia āpana, hiki ke hiki keʻikeʻia he mau uila e nānā. Akā, uaʻano haʻahaʻa ka uila e like me ka hapa nui o ia mea i alakaʻiʻia i ka honua e ka'ōnaehana pale uila i waho. Ma waena o LPZ0B a me LPZ1, pono e hoʻokauʻia ka Class 1 / Type 1 SPD i mea e pale ai i nā pūnaewele lalo.
LPZ2:ʻO ia ka lālā hoʻonā i loko o ka hale kahi e hiki ai ke piʻi liʻiliʻi. Ma waena o LPZ2 a me LPZ1, pono ka Class 2 / Type2 Keʻena palekana pale.
LPZ3: E like me LPZ1 & 2, ʻo LPZ3 pū kekahi kahi i loko o ka hale kahi i loaʻa ʻole a i ʻole nā nalu nalu liʻiliʻi.
