110kV LEVEL Ekolu-PĀNA MA KA LOAD TAP-CHANGE

HANA UILA

Hōʻuluʻulu manaʻo

Ua apono mākou i nā ʻano hoʻololi koʻikoʻi ma ka pae 110kV pae ʻekolu manawa i hoʻokomo ʻia i ka mea hoʻololi hoʻololi hoʻololi i ka ʻaila,
kaʻina hana a me ka hoʻolālā.Loaʻa i ka transformer nā hiʻohiʻona o ka liʻiliʻi liʻiliʻi, ke kaumaha māmā, ka hana kiʻekiʻe, haʻahaʻa haʻahaʻa, haʻahaʻa haʻahaʻa, hana hilinaʻi etc.
hiki ke hoʻemi i ka nui o ka poho o ka pūnaewele mana a me nā lilo hana me nā pōmaikaʻi waiwai nui.He kūpono ia no ka mea kanu mana,
pauku kaumaha mea kanu oka hui etc.
