❓ Help Ask ko lng po bakit iba yung kuryente sa city than province sa bansa natin?

[Vermouth the Gin]

Hi po mga ka phc
Ma tanong ko lng po bakit iba ang line to line volt sa city at province

Philippines has two different standards.
Rural is two wire L-N, at 230 VAC single phase.
Larger older cities are L1-L2 240VAC single phase with neutral center tap. (L1-N 120 VAC)

Dito po sa amin province L= 220 vac tapos neutral yung isa

Maraming salamat po sa pag sagot

Larger older cities are L1-L2 240VAC single phase with neutral center tap. (L1-N 120 VAC)

"...cities, residences are supplied with 240 volt, alternating current, 60 cycle power. Power from the utility transformer to the residence arrives through three wires, two 120 VAC load (“hot”) wires and a single neutral."

"It seems likely that the American-style 120 / 240 VAC 60 cycle used in Manila may have been the result of the fact that electrical systems in Philippine cities were expanded during the American occupation of the Philippines between 1899 and WWII."

Rural is two wire L-N, at 230 VAC single phase.

"Areas outside of the old established cities were electrified later and use a different and more economical system using a two wire service drop to the residence. This consists of one 230 VAC load wire and one neutral wire."

Isa pang kakaiba sa atin ay yung 60Hz sa halip na 50Hz
"Much of the rest of the world runs on 220-240 VAC but 50 cycle rather than 60 cycle found in the Philippines, creating a problem in importing some European appliances for use in the Philippines."

Thank you lods

Opo lods, pero ano kaya dahilan? Na curious lng po kasi ako
Iniisip ko kasi kaya 230 vac at neutral yung isa sa mga province ay baka dahil sa prone sa mga risk gaya ng falling trees , etc. Pag natabunan yung service drop wire sa puno ay yung ground or neutral lng ang mas napuruhan gaya ng na obserbahan
Ko d2 after typhoon odette, nadamage lng kasi yung hot wire o yung live unless pag may matulis o sharp object na nagdulot ng pagkasira.

Tapos sa cities nmn i think 120 to 120vac ay dahil incase pag na touch mo yung isa o na damage yung isang wire ay 120vac mababa compare dun sa 230vac na live mas masakit yun at i think mas safe yun sa cities dahil incase din pag may contact sa ground di malakas hatak sa kuryente. At i think dahil din sa sikip² mga buildingng sa cities yun po ang risk.

(caution lng po baka may makadaan dito na nag basa wla pang masyadong alam sa kuryente, wag na wag nyu pong subukan hawakan 230vac o 120vac pa yan pareho po yang dilikado.
Kung may i repair mn off the breaker)

I think lng po pa correct po anong tama.

Sa pagkaintindi ko sa article lods, nauna sa city yung 3 wire, kasi American Occupation, so US style ang nasunod
Tapos sa probinsya naman, na mas late nang nadevelop, 2 wire na, kasi mas economical

Pero siguro hintay taya ng Master Electrician, kasi na search ko lang din yan, hehe
