Why 230v

Now, historically speaking, one of the main reasons why the US stuck with V as its standard power supply largely has to do with the fact that it was initially tied to carbon filament lighting. So V was made the standard.

The United Kingdom is one area of the world that did change things up after setting up its power grid. It was much smaller than the United States version, but could not be supported after World War II when the UK began running out copper to rebuild its infrastructure.

To fix the problem, it decided to instead build the fuse into their plugs; this, as opposed to having all outlets connected to a fuse box individually. This is why the outlets in the UK are different from those in mainland Europe.

Voltage selector switches or taps were provided to move from one range to the next for this reason. Having a range of to V in a recent sophistication of wide input range switch mode supplies.

During the interim years there were manually or automatically range switched inputs that would support V AND V but values in between would cause faulty operation of hazard. Add a comment. The Overflow Blog. Does ES6 make JavaScript frameworks obsolete?

Podcast Do polyglots have an edge when it comes to mastering programming A volt air conditioner purchase price costs less than a volt model with the equivalent BTU rating. However, electrical consumption remains equal because power companies bill by wattage used. For example, a volt unit that uses watts of power costs just as much to run as a volt model that also uses watts of power. Better still, an Energy Star unit has the highest efficiency rating in its class.

Use the wattage consumed as a guide. The less wattage used to obtain a stated BTU rating, the more efficient the unit is. All this with simple transformers which have a relatively high efficieny. The same was not possible with DC. Anyway, not that easily. In fact, since it is DC, the losses are lower, because even at 60Hz there are some losses in an AC system, due to capacitive loading.

This is the drive behind the efforts, by Siemens for instance, to make high-voltage DC systems. I didn't search it and I could be wrong but it is understandable noting that russia is a big country that many consumers are far apart from each other.

Though VVV rightfully noted the negative effect of AC magnetic field on human and also another negative effect of AC is noise which is the most prominent noise in different devices but having in mind ever increasing thirst for energy air conditioners, electrical heaters, ovens, PaulHolland Advanced Member level 2.

Re: why volts for AC shwoo said:. Re: why volts for AC Operating an audio amplifier rated 50Hz off 60Hz mains does not usually cause any problems. But the other way around may sometimes cause overheating due to higher magnetizing current. If the appliance does not involve something like induction motors, you are okay.
