SPD no ke alakaʻi koho ʻana i nā ʻōnaehana lako mana
ʻO ka hoʻokomo ʻana o SPD i kēlā me kēia wahi palekana uila, e like me ke ʻano o ka hiʻohiʻona uila haʻahaʻa haʻahaʻa, e hana i ka hoʻohālikelike ʻana o nā mea uila e like me ke ʻano o ka over voltage, hiki i kona insulation ke kū i ke kiʻekiʻe o ka volta impulse ke hoʻoholo i ke koho ʻana o SPD.E like me ke ʻano o ka hiʻohiʻona uila haʻahaʻa haʻahaʻa, e hana i ka hoʻohālikelike ʻana i nā mea uila e like me ka ʻāpana over voltage e like me ke kiʻekiʻe o ka hōʻailona, ka pae hoʻouka, ka hāʻawi ʻana a me ka pae mana, ka pae mana.ʻO kona insulation e kū i ka pae uila impulse: 1500V, 2500V, 4000V, 6000V.E like me ka ʻokoʻa o ka hoʻonohonoho ʻana o nā lako uila a me ka ʻokoʻa o ka uila o nā wahi pale uila like ʻole, e hoʻoholo ai i ke kūlana hoʻonohonoho o SPD no ka lako mana a me ka hiki ke haʻihaʻi.
ʻAʻole ʻoi aku ka mamao o ka hoʻokomo ʻana ma waena o kēlā me kēia pae SPD ma mua o 10m, ʻo ka mamao ma waena o SPD a me nā mea i pale ʻia e like me ka pōkole, ʻaʻole i oi aku ma mua o 10m.Inā ma muli o ka palena o ke kūlana hoʻonohonoho, ʻaʻole hiki ke hōʻoia i ka mamao o ka hoʻonohonoho ʻana, a laila pono e hoʻokomo i ka ʻāpana decoupling ma waena o kēlā me kēia pae SPD, e pale ʻia ka SPD ma hope o ka papa mua.I ka haʻahaʻa haʻahaʻa haʻahaʻa mana lako ʻōnaehana, hoʻohui i kahi inductor hiki ke hoʻokō i ke kumu decoupling.
SPD no ke kumu koho kiko'ī kiko'ī o ka mana
Max.ka uila hana mau: ʻoi aku ka nui ma mua o nā lako pale, ka nui o ka ʻōnaehana.uila hana mau.

Kuhi ʻia ka hoʻokuʻu ʻana i kēia manawa: hoʻoholo ʻia e like me ke kūlana uila o ke kūlana i kau ʻia a me ka wahi pale uila.
