Please could someone clear this up for me as I keep getting differing information. As far as I know electrical utility companies charge residential consumers in W so power factor does not count. I am looking to convert a house to LED and energy saver lamps and these lamps have very bad power factors. I need to size the transformers for VA not W correct? As the actual power drawn from the transformer will be in VA.
Secondly if I know the power factor is 0.7 is it correct to say VA=W/pf? This makes the actual consumption huge!
