RE: Bi-Phase Power Supply

[nbashir786]

Hi All,

I am interesting in findanyone who has any pictures or experience of working on bi-phase power supplies. The site where I am involved needs to increase its demand and a bi-phase supply will be provided by the local DNO (Power Networks). Would I be correct to say this is two of the three phases of a three phase supply?



Any thoughts or assistance welcomed?



Regards

some places used to have 2 phase supplys ,if they wanted to run 3 phase equipment they had to use a phase converter to create a false 3rd phase

You can have two legs and neutral off a three phase transformer, or all three legs of a centre taped transformer. The centre being neutral.

BTW Bi-phase can be an American 90 degree phase shift system, search Scott transformer

Split phase is also a motor that runs off single phase. Hardly definitive is it?

Welding are quite often 2 phase.

It's about time we harmonised the word Phase to something no one understands.

i wired a 2 phase arc welder a few years ago, the colours in the flex were brown/blue/g/y!

I wired a 2 phase welder as a favour about 40 years ago.
Guy that owned it said it need 2 phases, that's what it got.

Pity it was set to 240v, went well for about 1/2 a rod..
