I am aware that in the US normal low voltage power distribution is one of the following: - 120V/240V two phase split voltage - 120V/208V three phase - 277V/480V three phase - 120V/208V/240V high ...

I came across a nice article about power factor correction for three phase systems. It is written with mil-standards in minds, as I do not even know if the European harmonic requirement applies to ...
