- bjelkeman-again 10y agohttp://electrical-engineering-portal.com/north-american-versus-european-distribution-systems http://electrical-engineering-portal.com/north-american-vers... > Most European transformers are three-phase and on the order of 300 to 1000 kVA, much larger than typical North American 25- or 50-kVA single-phase units.
- bonzini 10y agoThat's the network transformers. Homes usually get single-phase 230V, while larger users get three-phase 400V.
- the_mitsuhiko 10y agoThat is absolutely not the case where I live (Austria). You get multiple phases into your home, at the very least to garage and kitchen.
- MrBuddyCasino 10y agoElectric stoves in Germany are usually hooked up to a special 3 phase wire in the kitchen, but thats the only exception in can think of, at least for apartments.
- bonzini 10y agoOh, here in Italy we have only 3 kW power to each apartment, so gas stoves are prevalent.
- krzyk 10y agoNope, most electrical cookers need 3-phase connection and those are used all around Europe.
- ldp01 10y agobjelkeman-again is referring to kVA- a unit of power rather than voltage. Systems which run a higher consumer voltage (e.g. 230V) will tend to use higher kVA transformers compared to the American system (~110V). I believe this is because it is feasible to run longer cables when using higher voltage (higher voltage -> lower current -> lower thermal losses per metre of cable), hence it is economical to use fewer, larger transformers in a higher voltage system vs. a lower voltage system.
- bjelkeman-again 10y agoSorry, my intent was to show three phase electricity to the home in most European countries.
- bonzini 10y agoAnd I was confused by living in one of the (apparently) few countries without three-phase electricity. However, even here the network transformers do get three-phase.
