bjelkeman-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.
