siguro kasi mahirap lang tayo, mas makakatipid tayo kung 220V kasi mas maliit current(meaning mas maliit na conductor, required) na expected na dadaloy to transmit same amount of power na kayang intransmit kung 110V.
Opinyon ko lang yun,hehehehe, sa US naman mas concern sila sa safety kaya 110V.

most of the 3rd world country ay 220V/60hz. ang gnagamit mas mura kc ang production ng power at maintenance na rin,pag kaya na ng pinas bungkalin ang ilalim ng mga kalsada at dun magladlad ng mga electrical cables ayun 1st world na tau aheheheheh...

ewan ko nga ba 50 years ago firstworld country naman tayo.. we were even believed to be one of the super powers in asia next to japan.. kung naalala nyo NAIA was the largest most advanced Airport in ASIA noon.. bat nga ba nagkaganito ang Pilipinas...
Ewan ko rin kung bakit 220v ang pinas.. marami namang standards di lang 110 at 220.. hmmn ano kaya iniisip nila noon.. basta nandyan na eh di na mapapalitan yan.. hehehe
pero palagay ko parang tulad lang ngayun yan eh.. Politics..
Like yung panggagaya natin ng Gobyerno.. gusto natin tulad nito at noon.. parliamentary or presidential.. haaayyysss

oo nga no napansin ko din sa mga 1st world cities nasa ilalim ng lupa yung mga electric cables  |

wala pa rin kasi akong makuhang magadang sagot dito tRY ko ko lang ha.....ang grid kasi natin nagsimula sa voltage triangle na 138kv ang kalahati ng leg 69kv ito primary voltage ng mga substation natin, tapos pag nag Y ka don sa 69kv voltage triangle leg makukuha mo ang line to ground ng 69kv (40kv)tapos mag Y ka sa 40kv leg triangle makuha mo 24kv tapos mag y ka uli sa 24kv leg triangle makuha ang 13.2kv which is primary nang ating distribution sa mga bahay. Same process triangle o Y (delta o Y) dun sa triangle makukuha mo ang 220volts natin which is suppose to be a line to ground voltage. Taka ko lang may mga distribution na 220v line to line. Ang problema ko lang ay... before the grid, siguro marami narin ang mga GenSet sa mga Ibat ibang lugar dito sa atin di ba? Sinong Kuneho este... konseho ang nag decide na 138kv tayo at 220v sa mga bahay!!! Ang pikawild guess ko,... siguro ng e lay-out ang plan ng grid.... 500kv pa ang pikamataas na praktikal voltage kaya 138kv tayo, Kung e incircle mo 138kv voltage triangle ang perimeter nun ay 500kv yun ang limit voltage ng system natin...... Hope gets mo ko....bbbrrrbrrrrrrrr ewan ko...  yon lang po ang alam ko sa voltahe.... Ang Quest...... ko sino kaya ang nag decide? Sino kaya siya? o sila? na father(s) of our grid voltage!!!!!! |

Mas ok na siguro ang 220V. Sa mga 110V countries, mapapansin ninyo na kapag mga high power aircon, dryers, and heaters na ang gamit, puros mga dedicated 220V line na gamit.

oo nga no napansin ko din sa mga 1st world cities nasa ilalim ng lupa yung mga electric cables Napakaraming kailangang iconsider para makapaglagay ng kable sa ilalim ng lupa. Matindi din ang gastos dun dahil sisiguraduhin na ayos ang insulation dahil mahirap na bungkalin at magiinit sa ilalim yun na pwede magdahilan sa kung ano-anong aksidente... |

sa akin dapat dc, kasi halos lahat naman ng gamit ngayon dc na...... pati motors maganda kung e dadaan sa kontrollers diba?..........

oo nga ano....I think we are the only country that uses 220VAC with ungrounded two prong plugs na pang 110V and design and normally 220VAC is 50Hz in most countries.

normally it's 115V/60Hz and 230V/50Hz...
nakalimutan ko na kung anong bansa yung DC ang gamit...
ang mahirap sa DC is yung step-up / step-down...
pero karamihan ng electronic equipment natin kahit saksak mo sa DC ok lang...
ang mga hindi pwede normally nasa HVAC, like Airconditioners, Refrigerators, etc...mas mahal kung gagamit pa ng inverter...kung DC motor, may brushes, or kung Brushless DC, mas mahal...

Kung step-up siguro mahirap, kung step-down kailangan lang ng malaking resistors hehehehe |

sir, taga-leyte ako pero i don't know na meron DC ang transmission dito.. mahirap isipin e kasi dito din sa leyte(sa tongonan geothermal plant) galing ung kuryente sinusupply sa buong visayas.. |

hindi rin, basta mataas ang voltage,
sabi nila, naeliminate na "skin effect"(significant ba un sa 60hz? hehehe) and wala na ring issue sa power factor kaya less current ang dadaloy sa transmission lines.
