Saving Energy: 110VAC vs. 220VAC ?
Saving Energy: 110VAC vs. 220VAC ?
(OP)
I'm sure anyone (but me) her on this forum can answer this basic question, which has bugged me for years
.
If a system is powered by 220VAC, are you saving money from usage of electricity over a similar system that runs on 110VAC ?
Similarly, will you be saving money if your system is 480VAC vs. 220VAC?

110I=Watts
220I=Watts
If watts is constant (same process) then you can see how the current changes. This is a simple explanation but will do for now.

120V systems like in the USA requires 480V to 208Y/120V stepdown transformers,as 480Y/277 is the norm for commercial/industrial facilities.
Where as 415Y/230V systems do not require step-down transformers. So you do save transformer losses, besides initial the costs.
Also higher voltages have lesser voltage drops and can trasmitt a given power over longer distance for a given size of wire or more power for the same distance, compared to low voltage systems.
Cost is a relative term, what is not a big deal in a relatively prosperous country like USA is a big deal for developing countires or even other developed countries.
